Suzu Taniguchi/Relationships

Ryutarou Sakagami
Ryutarou is Suzu's boyfriend one year after she and the other students return to Japan. She is asked by him to return to Tortus to be an adventurer and spend their days together helping Kouki and the people, to which she accepts.

Kouki Amanogawa
Kouki is one of her friends from Earth and fellow adventurer.

Kaori Shirasaki
Kaori is one of her closest friends. Suzu tends to act perverted around her, but will always stand by her.

Hajime Nagumo
It is unknown how she felt towards Hajime prior to his fall into the abyss, but she felt sympathy for his supposed death as she hoped that he was still alive so Kaori could reunite with him. After seeing that Hajime is still alive and having obtained monstrous powers, Suzu became shocked that the once weak Hajime now turned into an ruthlessly indestructible monster and became terrified of him when he killed Cattleya without hesitation and threatened to kill them as well should they stand in his way. It's because of this newfound fear that she had no problems letting Kaori go to join him so as to not get on his bad side. Like the rest of her classmates, Suzu became even more terrified of Hajime when he brutally killed Hiyama for the latter's betrayal and threatened do the same to the rest of them when Kouki began to annoy him with his persistent delusions. However, Suzu (along with Shizuku and Ryutarou) managed to convince Hajime to give her and their former classmates another chance to join him as she wanted him to help her and the rest of the "Hero party" clear the Great Labyrinths in order to destroy Ehit so she could become stronger and see Eri again, hoping to return her to their fellow classmates. In her proper respect for Hajime, she addressed him as "Hajihaji". When Hajime began to enhance his classmates armors and weapons, Suzu handed her bracelets to him to be enhanced until they were destroyed as a failure which saddened her. However, Hajime gives Suzu a pair of twin iron fans (one of Hajime's greatest masterpieces) as a gift to compensate and she appreciated his gift. When she begged Hajime to give Eri a chance at redemption, Hajime obliged her pleas but stated that he will kill Eri if the latter doesn't redeem herself. After returning to Japan and Ehit's death, Suzu was the one who nicknamed Hajime as the "God Slaying Demon King" when she and all the other classmates appreciated him for his efforts of helping them to return back to Japan.

Tio Klarus
Tio feels a sense of comradery with Suzu since they both have perverted qualities. Tio liked Suzu when helping mastering the "metamorphosis magic" and later become close friends.

Eri Nakamura (deceased)
Suzu considers Eri her best friend and always will be. She is devastated by Eri's betrayal and it has an everlasting effect on her after revealed that Eri has never considered Suzu as a true friend from the start and wanted to kill Suzu and the rest of their classmates due to her and the others being in the way of making Kouki hers. In order to talk with her again, she begs Hajime to help them complete a labyrinth so she would be strong enough to do so. Suzu confronts Eri one more time but shown displeasure when Eri was transformed into an apostle hybrid as Ehit's servant. After Suzu fought and managed to defeat Eri, she begged Eri to find redemption but instead Eri used a self-destruction spell in attempt to kill Suzu but died in the process.

Ehit (deceased)
Suzu once respected the so-called "god" Ehit. However, after learning the truth from her teacher, Aiko, she lost all respect for the false god. She wanted to destroy Ehit and take back Eri. After Ehit transformed Eri into an apostle hybrid, Suzu swore that she'll will make the false god pay.

Daisuke Hiyama (deceased)
Like Ryutarou, Suzu holds hatred toward Hiyama for bullying people in school including Hajime and his selfish lust for Kaori. When Hiyama temporarily murdered Kaori, her hatred toward the latter increased. Though she has shown to be fearful when Hajime brutally murdered Hiyama and like most of her classmates, she hold no ill will towards Hajime for killing Hiyama as she will never forgive him for what he's done.
