Once the kingdom was invaded, Daisuke killed Kaori so that Eri could turn her into his undead servant.

Personality
"I’ll kill you! No matter what it takes, I swear I'll kill you!"

- Daisuke to Hajime

Daisuke acted as a typical bully and enjoyed taunting others. He especially enjoyed bullying Hajime due to the constant attention that Kaori was giving him. After being transported to Tortus with his class bestowed with Magic, his bullying rose to a greater extent where he used violence and justified it as a way to train.

Despite his enhanced stats and affinity with magic, Daisuke is not the best of warriors, he is shown to be a reckless individual, falling for a very obvious trap which nearly resulted in the annihilation of the entire party during his first exploration of the Great Orcus Labyrinth. Daisuke was shown to be a disloyal and cowardly individual, as he was willing to abandon others if necessary. He was even willing join the enemies' side if it stood to benefit him. When Eri first discovered Daisuke's treachery in attempting to kill Hajime and blackmailed him into serving her, he ultimately choose to do so in order to save himself.

Daisuke was obsessed with Kaori and did everything in his power to make her his woman. This served as primary factor for Daisuke's bullying towards Hajime. This is mainly due to how he sees Hajime as inferior, and it's unfair that Kaori shows more affection towards Hajime instead of his clearly superior self.

After his attempted murder on Hajime, Daisuke became paranoid and feared of being caught, while also trying to rationalize his actions. Later, upon learning of Hajime's survival and seeing his newfound strength in person, his fear grew even more due to believing that Hajime would seek vengeance on him, as well as having lost his opportunity to win over Kaori when she decided to travel with Hajime.

Overtime, Daisuke became more devious and had gotten to a point where he had no longer had any qualms of killing others in order to achieve his goals, and managed to ease his copious by telling himself that he was doing it for his and Kaori's sake. Even so, he was disturbed at the lengths his co-conspirator Eri went to in order to achieve her goals.

Biography
One Monday morning during his second year of high school, Daisuke and his three friends Yoshiki, Reichi and Shinji were verbally harassing Hajime after he barely arrived in time before class began.

When it became lunchtime, Daisuke and his class were suddenly engulfed in a large glowing circle that transported. Once it was over, everyone saw that they were suddenly inside a large cathedral. Soon after, they were approach by Pope Ishtar Langbard of the Holy Church, and explained to them that they had been summoned the alternate world of Tortus by humanity's god Ehit, in order to aid in their war against the Demons. When Ishtar revealed that Ehit was the only one with the power to send them home, the students agreed to fight alongside the Humans of Tortus, against the protests of their teacher Aiko Hatayama. The next morning, Daisuke and the rest of his classmates gathered at the palace courtyard to begin their training. They were greeted by the kingdom's Knight Commander Meld Loggins, and were each given a Status Plate artifact before he explained how it worked to everyone. As the students began to activate their plates, Daisuke and his friends were making fun of Hajime after it was revealed that he had the common Job of "Synergist", as well as possessing average Stats. Over the next two weeks, the students trained in the kingdom in order to prepare for the war against the Demons. During that time, Daisuke and his friends continuously harassed Hajime by attacking him with their magic, but would stop whenever they were confronted by their classmates Kaori, Shizuku, Kouki and Ryutarou.

Once the students' initial training complete, they traveled to the Outpost Town of Horaud, in order to explore the Great Orcus Labyrinth and battle the Monsters that resided there as a way to gain more combat experience. The night before the students beginning their exploration, Daisuke had been too nervous to sleep in the room of the in. the students were staying in. He stepped out to go to the bathroom and feel the night breeze. As he was about to return to his room, he spotted Kaori in a negligee. He had been so surprised by her sudden appearance that he had reflexively hid himself from her sight. Kaori hadn’t even noticed he was there as she passed by. His curiosity piqued, he’d followed Kaori and watched as she Hajime’s room. This immediately angered Daisuke at the fact that Kaori was willing to spend time with someone like Hajime, rather than him, and began to think of a way to get her to notice him.

During the their exploration into the Great Orcus Labyrinth, Daisuke tried to take a giant Glanz Crystal on he 20th floor, in an attempt to impress Kaori, but it turned out to be a trap and transported everyone to the 65th floor. They soon found themselves at a stone bridge and was trapped between a Behemoth and and army of skeletal Traum Soldiers numbering in the hundreds. Hajime managed to hold the Behemoth back his transmutation magic while the others managed to create an escape path through the skeletons. As Hajime rushed his way towards his classmates, Daisuke attacked Hajime with a fireball spell while everyone was busy bombarding the behemoth with their magic, and caused him to fall off the bridge.

After everyone else escaped from the Labyrinth and returned to the inn, Daisuke left that night to an isolated spot in Horaud. He squatted down and continuously spoke to himself about having killed Hajime without anyone being able to trace it back to him. It was then that he was approached by one of his classmates who overheard what he said. After gleefully calling Daisuke a murderer, this individual threatened to expose Daisuke's secret unless he agreed to become a slave. Feeling corned by this choice, Daisuke was thinking of a way to kill his blackmailer, but his classmate managed convince him to accept the offer of becoming a slave by promising to make Kaori his woman. Daisuke asked what his classmate wanted from all of this, but simply answered that it was something that didn't concern him. After Daisuke accepted the offer, the two of them headed back to the inn.

A few days after the students returned to the kingdom, Hiyama began to be shunned by the other students. As Hajime's apparent death began to sink with them, they took out their anger on Daisuke, due to him having activated the Labyrinth's trap that transported them to the room where it happened. In an effort earn their forgiveness, he got down on his knees and publicly begged them for it, in the hopes that doing it in front of Kouki, the class' hero, would help smooth things out with the rest of his classmates. Ultimately, his plan succeeded, and mosts of the students quickly stopped directing their scorn at him. However, Shizuku was still vaguely suspicious of him. Meanwhile, Daisuke began surreptitiously carrying out the orders he’d received from his blackmailer. Despite the dark nature of these orders, he had agreed to carry them out.

Daisuke was among the students that resumed their training in the Great Orcus Labyrinth, in spite of the dangers they knew it contained. As they managed to become stronger and advance deep into the Labyrinth, Daisuke and his friends grew more arrogant and expressed their belief that they were invincible (though they remained humble while in the presence of Kouki and his friends). As they reached the 65th floor once more, they once again encountered the Behemoth and traum soldiers. Despite the lingering trauma from their previous encounter, as well as the fact that there were less people of fight it than before, the students managed to defeat the Behemoth and continued their journey down the Labyrinth.

Daisuke and the other students continued their training in the Labyrinth until they eventually reached the 90th floor. However, they soon realized that they were not being attacked by any Monsters. It was soon discovered that they had all been wiped out by other Monsters that were under the command of a Demon named Cattleya. She approached the students and offered them to join the Demons in the war against the humans, but Kouki immediately refused on their behalf and a battle ensued that forced the suddens to retreat to the 89th floor. However, Cattleya discovered their location and proceeded to attack them once more. In the end, she managed to defeat them after having incapacitated Kouki, and offered the students another chance to join the Demons. Daisuke voiced his desire to accept the offer, which immediately angered Ryutarou and proceed to call him a coward, but Daisuke argued that hey had no choice, given the overwhelming straight of Cattleya's Monsters. Kouki tried to convince them to reject the offer, but Daisuke argued that they should focus on getting out alive no mater what. As Dashiki was about to accept Cattleya's offer, Kouki managed himself from the Monsters that were retraining him, and proceeded to attack the Demon, but stop upon realized that he was about to kill an actual person. As the Monsters resumed attacking the students and were on the verge of victory, they were stopped by the sudden arrival of a mysterious boy that had accompanied Kousuke Endou (who managed to escape the Labyrinth after Cattleya's first attack in order to find help for his classmates). When Kousuke revealed that was actually Hajime Nagumo who had come to their rescue, Daisuke was utterly shocked and immediately accused him of lying. Kousuke vouched for Hajime and even claimed that he saw his Status Plate earlier to confirm his identity, but Daisuke insisted that it had to have been a forgery. Hajime's companion and lover Yue magically doused Daisuke with water and demanded him to be quiet. Daisuke was unable to argue after seeing Yue intensely glare at him. Once Hajime eliminated all of the Monsters and killed Cattleya, Daisuke joined Kouki in criticizing Hajime for having killed a defenseless opponent, in a bid to discredit him in front of Kaori, but this proved unsuccessful.

As everyone was making their way out of the Labyrinth, Daisuke and Reichi attempted to get closer to Hajime's companions Yue and Shea, but the two girls ignored them completely. This annoyed Daisuke, and tried to grab Shea’s ears, but was hit by a rubber bullet from Hajime.

When Kaori decided to accompany Hajime on his journey after they returned to Horaud, Daisuke begged Hajime to rejoin their party, in order to keep Kaori close by, and even apologized for his previous bullying. However, Hajime refused his offer by subtly dropping hints that he knew that Daisuke was the culprit behind his fall into the Labyrinth's Abyss. Daisuke became nervous at Hajime's words, to which Hajime followed by by calling him and his friends worthless and threatened to kill him if he got in his way. While his friends were outraged by Hajime’s attitude, Daisuke instead complied with Hajime before telling his friends to back down. At first, they were surprised by Daisuke’s uncharacteristic obedience, but his serious tone brooked no argument, so they too gave up on persuading Hajime. As Kaori was getting her thing from Horaud's inn before setting off, Daisuke and his friends offered to go with her, but Hajime prevented them from going.

The light after Hajime's departure with Kaori, Daisuke travelled to one of Horaud’s public parks, and vented out is frustration over having lost his love interest, by punching the surrounding tress while cursing. Just then, his accomplice appeared from behind the bushes and openly mocked him for having lost the women he desired. This only served to further anger Daisuke, and threatened to no longer be treated as a slave since Hajime was alive, but his partner assured him that Kaori would still become his once she returned to the kingdom by incentivizing her to protect her friends. Daisuke decided to continue aiding his co-conspirator, despite knowing that meant betraying the rest of his classmates.

Betrayal and Death
Daisuke participated on killing the kingdom's knights at the behest of his partner. One evening, Daisuke approached Meld in his room and asked for his help with something. When Meld invited him in, Daisuke was hesitant to talk about what was wrong, but Meld assured them that they could work it out together. However, their conversation was cut short when Knight Vice-Commander Jose Rancaid approached Meld's room as well. Daisuke offered to wait in the hall until Meld and Jose were done talking. As Meld opened the door, Jose suddenly attacked him with his sword, but Meld dodged him before grabbing his own sword. As the two knights fought, Meld was about to unleash a wind spell on Jose, but was interrupted when Daisuke suddenly stabbed him from behind. Meld, however, instinctively dodged it fast enough to avoid it hitting his heart, much to Daisuke's annoyance. Meld attempted to ask Daisuke for his sudden attack, but he ignored Meld’s question, and once again tried to stab Meld’s heart. Meld then cast his spell by and unleashed a compressed ball of wind that slammed into the floor and sent all three of them away in different directions in the room. Meld then regained his bearing and was about to attack Daisuke, but was intercepted by more knights that suddenly appeared. Despite Daisuke and the knights attacks, Meld managed to counter them before managed to severely tackle Daisuke. After Meld managed to subdue the remaining knights, Daisuke expressed his frustration at his inability to kill Meld, and even called him a monster due to his skill. Mel, however, claimed that his simply had much more experience when it came to fighting people and hoped that his recent display of fighting prowess would be enough to get Daisuke to surrender. Instead, Daisuke mocked Meld for his confidence before even more knights came to his aid. As Meld was suddenly surrounded, Daisuke demanded that Meld let himself be killed, but Meld decided to flee and jumped out of a window and landed safely outside by using his wind magic. Unfortunately, Meld was killed moments later by a mysterious woman. Afterwords, Daisuke was approached by his accomplice and the two of the discussed how despite they needed the aid of that woman to kill Meld, their plans were proceeding smoothly after having gotten rid of the last obstacle in their way.

Several days later, when the demons invaded the Heiligh Kingdom, all of the students discovered that Eri was a traitor after she commanded her army of undead knights to injure and subdue her classmates within the palace courtyard. When Eri attempted to kill Shizuku, she was stopped by Kaori, while being guarded the barrier magic of Princess Liliana. Eri ordered her knights to attack the barrier, and one eventually managed to break through, but Daisuke suddenly appeared and beheaded the soldier. At first, he appeared to have come to resume Kaori and Liliana, but Shizuku suspected it to be a trap and attempted to warn them. However, Daisuke stabbed Kaori from behind as soon as she let her guard down. As she lay dying, Kaori used the last of her strength to cast a healing spell on her classmates in order to help free them from Eri's knights. Daisuke attempted to stop Kaori by continuously ramming his sword through her, but she succeeded in unleashing her spell, though she was unable to heal herself due to the severity of the wound. As Kaori's classmates attempted to rescue her, Eri began to cast her "Spirit Binding" spell on Kaori's body in order to turn her into an undead minion for Daisuke. However, before she could complete her spell, Hajime suddenly arrived and caused everyone to freeze in fear. He took advantage of this brief pause and immediately approached Daisuke with such incredible speed. Hajime knocked him straight to the courtyard wall, which left him half-buried in the rubble. Daisuke spasmed and coughed out blood. His internal organs had been pulverized, and most of the bones in his upper body shattered. The pain was so great that it knocked him unconscious, and then woke him up again, but rendered him unable to move.

When Hajime was about to kill Eri after having quickly dispensed with her undead knights, Daisuke foolishly attacked Hajime with a fireball before charging towards Hajime with his sword. Hajime easily neutralized Daisuke's spell by shooting at its core with his handgun, then quickly stopped him by kicking him in the chin before slamming him to the ground with an axe kick to his skull. As Daisuke’s head bounced back up, Hajime kicked it again, sending him flying into the air. He held back so that Daisuke would regain consciousness instead of die. As he fell back down, Hajime grabbed the back of his collar and held him up. Daisuke struggled against Hajime’s grip, but to no avail. Daisuke then screamed a Hajime by blaming him for Kaori not being his. Hajime, however, was unfazed by Daisuke's rants, and instead stated that that it was Daisuke's own fault for how things turned out for him. Rather than repent for his actions, Daisuke vowed to kill Hajime. After sparing one final look of pity, Hajime threw him up and punched his face before sending him away with a kick to the abdomen. Daisuke landed outside the courtyard, where he was quickly assaulted by the monster army. His left arm had been eaten off before he attempted to crawl away to safety, but he was quickly caught and eaten from the feet up, thus killing him and bringing an end to Hiyama's delusions of Kaori.

Legacy
After the war in the Heiligh Kingdom, Daisuke's remains were discovered and buried in an unmarked grave by the kingdom's monument known as the "Cenotaph of Brave Souls". His longsword, as well as Reichi's spear, were adorned there as offerings.

After the remaining students returned to Earth, Daisuke's family learned of his death through Hajime and Aiko. They attempted to get revenge on Hajime for killing him, but suffered a complete breakdown by mysterious means from Hajime in retaliation for their efforts.

Relationships

 * Hajime Nagumo - Daisuke's former bully victim from the past, but now his direct murderer. Daisuke hated the fact that Kaori was interested in Hajime and not him so he decided to make Hajime's life as miserable as possible. This would later escalate to physical violence after they were transferred to Tortus and Daisuke obtained a strong combat job compared to Hajime's non-combat job. It would escalate to attempted murder after he saw Kaori coming out of Hajime's room one night. Later, after finding out Hajime had survived the fall into the abyss, he begins to feel scared and intimidated that his plan will be exposed and witnessing Hajime's monstrous strength. After Hajime murdered Cattleya, Daisuke became terrified of Hajime's demonic powers and ruthlessness. When witnessing Hajime tell Kouki that he will kill him even if they were classmates, Daisuke became even more afraid. When Kaori declared she is leaving with Hajime, Daisuke's fears became even worse when he witnessed Hajime easily defeat Kouki in an unarmed duel of which Kouki attempted to take Hajime's party (harem). When Hajime and his party prepared to leave for their journey with Kaori, he became desperate along with his gang and pleaded with Hajime to rejoin the Hero party (just so he would be closer to Kaori) while feigning an apology for the treatment they gave him in the past, but in response Hajime told Daisuke that he doesn't care for his early mistreatment anymore and gave him some hints that he knows what happened by calling him and his gang worthless and weak, subtly warning Daisuke to stay out of his way if Daisuke wished to stay alive. This caused Daisuke to fall into insanity as not only has Hajime obtained strength far superior than him, but lost his chance getting Kaori to become his girlfriend. Even in his insanity, he feared if he harmed Hajime's harem (including Kaori), he will be killed by Hajime in cold blood. Later on, after he killed Kaori and Eri's attempted "Bind Soul" failed, because of Hajime's arrival, the wounded Daisuke became mad and attacked Hajime with a fireball (but has no effect on him) while badmouthing Hajime for his own failure to make Kaori his girlfriend, but that only enraged Hajime even more as he brutally thrashed Daisuke as he breaks almost all of Daisuke's bones and damaged his internal organs. While Hajime gripped the severely wounded Daisuke at his neck, he blamed Hajime for getting Kaori's attractions but Hajime responded as he told Daisuke to stop blaming others and sadistically tormented him as the latter considered his level to be a stoop while back at school and on Tortus due to his lack of responsibilities, citing him as a man who sat around insulting people as like and calling him a weak, selfish and pathetic bully, the main reason of which Kaori will never fall in love with him and will never become his girlfriend for the rest of his worthless life. When Hajime was willing to offer him to repent his actions and realize his wrongdoings in order to spare him, the dimwitted Daisuke persistently bragged his final words that he will kill Hajime and make Kaori his girlfriend one day, which Hajime saw as only an empty threat. With this insolence, Hajime has no choice but to put Daisuke out of his misery, by kicking him out of the courtyard and into a group of Freid Bagwa's monsters where he was left to be eaten alive, thus putting an end to Hiyama's delusions of Kaori forever. Hajime then ruined Daisuke's already tarnished reputation when he enlightened his classmates the truth of his "fall" incident, particularly how it was never an accident, which caused the so-called "heroes" to lose the slightest sympathy they originally had for Daisuke and completely write him off as a self-deluded traitor as payback for his sins and deception.
 * Kaori Shirasaki - Daisuke was obsessed Kaori to the point where he would do anything just to obtain her. At first, he did not feel that he was worthy to be with her due to her constantly hanging around Kouki, and was content to simply admire her from a distance, but decided to make a bid to make her is his woman after seeing how close she was with Hajime. He was even willing kill her so that Eri could turn her body into an undead puppet who would listen to his every command, only to be foiled by Hajime, who eventually killed him for what he has done. Hiyama's death at Hajime's hands has brought an end to his delusions of Kaori forever. When she was revived by Hajime, Kaori lost all of her sympathies for Daisuke and replaced it with a complete hatred toward him as well like everyone else, to remember Daisuke Hiyama as a traitor after what he did not only to both her and Hajime, but also the innocent lives for Eri's schemes.
 * Eri Nakamura - One of his fellow classmates. After she discovers that Daisuke was the one who attacked Hajime in Orcus Labyrinth, he was blackmailed by her and forced to work with her. Daisuke respected and feared Eri's devious nature, but despised having to be subservient to her, and only went along with her plans in order for her to make Kaori his woman. However, when Hajime arrived and foiled her plans, Eri revealed she only viewed Hiyama as a pawn and left him to die without a second thought in order for her to escape from Nagumo as well renegading their deal. Eri, like everyone else, considered Daisuke Hiyama as worthless.
