Ryutarou Sakagami (さかがみりゅうろう, Sakagami Ryutarō?) is a major character from the "Arifureta Shokugyō de Sekai Saikyō" series.

He is one of the students from Japan who got involved in the Summoning Incident, and ended up in Tortus along with his other classmates. He is the childhood friend of Kouki Amanogawa, Shizuku Yaegashi & Kaori Shirasaki; and was part of Kouki's party during the training in Orcus Dungeon. He is also the boyfriend of Suzu Taniguchi.


Ryutarou has a physique is like a bear and he stands tall at about 190 cm. He has short trimmed hair and a gaze that appears both cheerful and stern.


I wanna get strong enough to protect my friends at least. I don’t ever wanna be helplessly forced to watch my friends die ever again.

Ryutarou is your typical energetic muscle-brained person. He values hard work and tends be rash in his actions. While he's not as dense as Kouki, Ryutarou is still pretty slow when it comes to understanding women feelings.

He is extremely loyal to his friends, especially Kouki. He is always the first to stand by his best friend side whenever he decides to do something, no matter how crazy it was. This makes him the opposite of Shizuku, who always tries to get Kouki to think before he decides to do something reckless, but will still support him. He will also be the first to defend his friends, both verbally and physically. After the demon invasion on the Heiligh Kingdom, Ryutarou resolves to get stronger so he wouldn't have to see another friend get killed before his eyes. After Hajime murdered Hiyama and saved Kaori, he is even willing to beg Hajime to help them conquer a labyrinth, something Hajime had never seen him do, showing he values his friends over his pride as he doesn't condemned Hajime as he will never forgive the traitor, Hiyama for his betrayal unlike Kouki. Following Hiyama's death and Eri's defection, He developed great respects for Hajime for saving his life twice and was impressed with him being able to survive his fall into the depths of the Orcus Dungeon. He shown his gratitude as he thanked Hajime after reviving Kaori. Unlike Kouki who is dense, Ryutarou has no qualms of letting Shizuku and Kaori be in romance with Hajime as his blessing for him due to Ryutarou already relationship with Suzu. When tested his newly enhanced gauntlets, Ryutarou's respects for Hajime had suddenly increased even further when witnessing his gauntlets' new powers. Unlike Kouki, he doesn't has a lust for his childhoods friends (Kaori and Shizuku) or Hajime's harems (Yue, Tio and Shea) when he is already in a romance with Suzu.

Ryutarou admires military soldiers and views "Gunnery Sgt. Hartman" from "Full Metal Jacket" as his idol. When seeing Hajime training the Haulia Tribe, he considers Hajime as a pupil of Sergeant Hartman. He hold in great amazement of Hajime's Artifacts are similar to the military army's firearms, weapons, vehicles and technologies which are similar from Ryutarou's favorite action movies. He loves military training and begged Hajime to train him and has a touching momentum strong enough to allow Hajime to train him.

As revealed in the Frost Cavern of Schnee, Ryutarou has always felt bothered that he's always been something of a side character compared to Kouki and Hajime. While he never showed it, he's always been jealous that all the girls once liked Kouki, and later Hajime, even though he also helped them as well.  Ryutarou has no jealousy toward Hajime for earning the love of beautiful girls including his childhood friends (Kaori and Shizuku) whom Ryutarou readily gave them as his blessings due to his already relationship with Suzu unlike Kouki. Ryuutarou is extremely selfless as he refused to allow his own desires to control him and hurt others for self satisfication, despite his jealousy towards Kouki, he did not bear any resentment and ill will towards the latter and had even originally intended to remain behind in Tortus to support Kouki to help him defeat Ehit despite Hajime offering him and his other classmates to return back home early.  even the Schnee Labyrinth doppleganger trial could not detect enough negative qualities in Ryuutarou to used against him. Despite his muscle brained personality, Ryutarou is also smart and wise enough to completely resist the temptation of his doppleganger trial allowing him to defeat it unlike Kouki.

In the Haltina Labyrinth, while transformed into an Ogre and deprived of his gauntlets, Ryutaro was able to fight on pair with another Ogre using a Karate based Martial Arts for a certain period of time, a considerable feat as the monsters of the Haltina Labyrinth are far more powerful and dangerous than the ones he had fought before despite suffering serious injuries in the process.
