Ryutarou Sakagami (さかがみりゅうろう, Sakagami Ryutarō?) is a major character from the Arifureta: From Commonplace to World's Strongest 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.


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.

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 very 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. 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. He shown respects for Hajime but fear his strength after survived and changed his appearance. He have his gratitude for Hajime after reviving Kaori. When tested his newly enhanced gauntlets, Ryutarou's respects for Hajime had suddenly increased even further when witnessing his gauntlet's new powers.

Ryutarou admires military soldiers and viewed "Gunnery Sgt. Hartman" from "Full Metal Jacket" as his idol. When seeing Hajime training the Haulia Tribe, he considers Hajime as a pupil of "Sgt. Hartman". 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 liked Kouki, even through he also helped them as well. At the same time, he's always been scared that he tried to challenge Kouki or Hajime, knowing he would just lose thus proving that he's really is a worthless sidekick.
