Kouki Amanogawa (あまがわこう, Amanogawa Kōki?) is a main 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 somewhat like the leader of the whole class, as students look up to him.


It is said in the story he is a perfect man. With Good looks, Athletic, Smart, and a good personality. He has silky brown hair and gentle eyes. His body was toned and slender at about 180cm. 


Kouki is a kind, fair, and overflowing with sense of justice. However since he never thinks he's wrong, he has a bad habit of interpreting adverse situations to his own convenience. This stems from his childhood. During his childhood he greatly admired his grandfather that would teach him his ideals of righteousness and justice. After his grandfathers death, Kouki held to his grandfathers teaching of ideal righteousness. Even so, the righteousness that his grandfather taught didn’t recognize good and evil at all. To further say it, Kouki came to think that what the majority of people thought as right was the absolute right. As he grows, he is capable of overcoming many problems while holding to his ideal. As a result, without realizing it, Kouki came to not doubt his own righteousness. Despite being cautioned by several people close to him, especially by his parents and Shizuku, he ignore it and simply believe in his righteousness.

Because of this, Kouki can't accept things when it doesn't go the way he wants. Such as when Kaori decide to follow Hajime on her on will, he cannot accept it as he always believe that they should be together forever and would rather believe that Hajime is the one that took her away.

He has a large amount of charisma but always charges straight forward without thinking of the consequences. He also has a naive, childish outlook on the topic of love and the topic of killing.


Kouki is your typical ikemen (handsome boy). On earth he is very popular but he doesn't notice it, even when he was summoned he was still dense. He first met Shizuku when he came to learn kendo in the Yaegashi dojo as a child. Kouki was very popular in school and thought to be attractive by many of the female students, but none of them approached him due to him always hanging around Shizuku. The two of them later met Kaori and she would hang out with them as well.

Kouki's skills in kendo earned him several interviews and magazine photoshoots.

When he first saw Hajime after he fell into the abyss he couldn't believe it was him.
