Ryutarou Sakagami is one of the major characters of Arifureta: From Commonplace to World's Strongest. He is the best friend of Kouki Amanogawa and childhood friend of both Shizuku Yaegashi and Kaori Shirasaki.

Personality
He 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 loyal to his friends and doesn't look down on Hajime before he fall. He feared and shown respects the mutated Hajime after he murdered Cattleya. He admired military soldiers and idolized Gunnery Sergeant Hartman as he considered Hajime to be a pupil of his idol. He loves military training methods as he dream is to become a police officer. He has a strong touching momentum of begging Hajime to train him as he considered him a friend. Unlike Kouki, Ryutarou doesn't condemned Hajime as he murdered the traitorous creep, Daisuke Hiyama as Ryutarou has such terrible memories of how his absolute hatred toward Hiyama even worse when he temporarily murdered Kaori as he will never forgive Hiyama for what he have done even in school and Tortus. He take Hajime's warning seriously as he let Hajime to have his childhood friends (Kaori and Shizuku) to be him to ensure not to get involved on Hajime's bad side. After Hajime revived Kaori, Ryutarou given Hajime his gratitude. His touching momentum has also allowed Hajime to spare Kouki's life and give him chances. Seeing conflicted between Hajime and Kouki, Ryutarou viewed himself to be weaker than Kouki but more weaker than Hajime as he deemed himself to be a worthless sidekick.

Unlike Kouki, Ryutarou wish to get him a girlfriend who loves him not to eager to get one for himself as he got Suzu Taniguchi as his girlfriend. He has no romance feelings for Kaori and Shizuku as he only considered them as friends not lovers and allowed them to be in romance with Hajime.
