	~ Kouki's delusions before his defeat by Hajime

Kouki Amanogawa is one of the main characters of Arifureta: From Commonplace to World's Strongest. He is one of Hajime Nagumo's classmates (but not friends) as well as the self-proclaimed rival of Hajime.

After the demons invasion the Heiligh Kingdom and facing an undeniable reality of due to his native expectation of his classmates' possibilities for betrayals (such as Eri and the now deceased Hiyama), Kouki (along Ryutarou Sakagami, Suzu Taniguchi and Shizuku Yaegashi) travels with Hajime and his party to clear the remaining labyrinths and kill Ehit. While corrupt by his doppelganger's temptation, he foolishly attempt to kill Hajime and take his lovers to "save the world" in Ehit's behalf but only to be easily defeated by Hajime once more and failed his trial for "Age of Gods" Magic leaving Kouki as the weakest due to him unable to obtain ancient magic.

He is voiced by Tetsuya Kakihara in the Japanese version of the anime, and by Ricco Fajardo in the English version of the anime.

Personality

As a child, Kouki admires his paternal grandfather's righteousness. When believe he will grow up to make his own righteousness.

He is a completely arrogant, delusional, idiotic, persistent, and annoying boy even toward his childhood friends and classmates as well to Hajime and his lovers due to his low intelligence and his lack of resolves. He is considered to be an immature and a loudmouthed moron when annoying others. Kouki believes of his righteousness of always oblige and helping each other. Unfortunately, this oblige has tremendous weaknesses which does allow the intelligent, Eri Nakamura and the treacherous idiot, Daisuke Hiyama to betray him and the party without even noticing. Worst of all, he enforced his justice which is his greatest weakness by spare his enemies only for them to defeat Kouki due to enemies has no feelings for him or anyone. Even worse that his weaknesses has made a fool of himself due to Kouki's lacks of resolves and low-intelligence. He believes he will give Hajime's harem better treatment if they leave Hajime but only for them to getting extremely annoyed by his ignorance and caused Hajime's step-daughter, Myu to cry by Kouki. After Hajime's lover rejected him for his ignorance, Kouki foolishly challenge Hajime into an unarmed duel to claim his lovers by force only to be easily defeated by him and ended such a worthless duel. Reason of Hajime didn't tell Kouki that Ehit's true nature to be an evil manipulator is due to Kouki's naivety and ridiculous habits of "justice".

Kouki dislikes Hajime when he got a lot attractions from Kouki's childhood friends, Kaori Shirasaki, Shizuku Yaegashi and later women who has an exceptionally and capacity of beauty which par both Kaori and Shizuku (such as Yue, Shea Haulia and Tio Klarus) but for Kouki losing all of his attractions from girls even in Tortus and returned back to Japan. When Kouki was corrupted by his trial doppelganger, he stubbornly believed that they were "brainwashing" by Hajime (which he doesn't have that ability). Kouki is insane of challenging Hajime to think he can defeat him to his failed attempted to take Hajime's lovers but only to be humiliated by Hajime by tossed Kouki into a pitfall with non-lethal bombs during his first defeat in an unarmed duel by Hajime without efforts. According to Shizuku, Kouki is more delusional as he doesn't know anything about Hajime or rather refused to known about Hajime of what he is or was even his lovers who are happy for Hajime. He doesn't take Hajime's absolute warning seriously in spite of his monstrous strength and ruthlessness. While his attempted to prove himself to be better than Hajime, things gotten worse for Kouki as he failed to clear every single labyrinths and Hajime cleared many labyrinths with ease as a result of Kouki losing to Hajime in both strength and willpower. Kouki is completely gutless when Hajime killed the traitor, Daisuke Hiyama. After learned of Ehit's evil nature, Kouki furiously asked Hajime why didn't he telling him and the party of Ehit's cruelty early only for Hajime claimed he won't believe him and get mad at him. It was Kouki's delusional idealism is at fault of always of his classmates help and protect each other which are the very weaknesses to enable other classmates' possibilities for betrayals such as both the intelligent, Eri Nakamura and the traitorous idiot, Daisuke Hiyama to betrayed him without even noticing. He became silent and disappointed when Hajime gives him chances but kept his warning of Kouki will meet the same fate as Hiyama did. When Kouki's corrupted by his doppelganger, he weakly attempted to kill Hajime and claim his lovers to force him to join him and "save the world" on behalf of Ehit but only to be easily defeated by Hajime once again when his defensive abilities were broke through with just one kick and continually thrashed him. He has a problem with killing believing it was wrong when Hajime killed the demon woman, Cattleya which is one of Kouki's greatest weaknesses. He believed that people would say same thing but only for Hajime claimed that everyone would say it's kill or be killed in Tortus. When realized how Hajime was mutated as the reason Kouki could never match up to his classmate, he felt sympathy.

Kouki was once popular to girls but he desired to marry his two childhood friends, Shizuku and Kaori which makes him a pervert. Despite of being his childhood friends, Kouki became disappointed when Kaori and Shizuku are not interested to be in romance with him or to marry him as they only wanted to be just friends due to them already have romance feelings and wanted to marry Hajime. Not only his obsessive for Kaori and Shizuku, but also Yue, Shea and Tio who became Hajime's lovers. He let his delusional pride and his empty idealism combine his perverted nature of believing Hajime mistreated them and offer them to leave Hajime and join him for "better" treatment which greatly annoyed and disgusted them. However, due to Hajime's new appearance, Kouki got extremely jealous and lost all attractions from girls. Following his defeat by Hajime yet again, Kouki brags if would've been him fall into the abyss, he would get Kaori and Shizuku's attraction only to get slapped in the face by Kaori and yelled at him to stop doing such hurtful things which saddened and silent him for his insolence. Despite of lost almost all of his attractions from girls, Kouki managed to found romance when he got kissed by the former queen, Moana and the former goddess.

After the story, Kouki simply abandoned his misguides of justice and all of his confidences. He is disappointed when his ideals only almost breaking his friendship for both Kaori and Shizuku. He no longer hesitate for his enemies.

Abilities And Powers

• Overload: After using "Limit Break - Overload", the side-effects of this power has severely damaged his body and became heavily fatigue.
• Manipulation: Due to his weak mind and delusions, Kouki is easier to be manipulated by anyone. Reason of Ehit blessed as the strongest due to his idiotic of justice. He was easily manipulated by Hiyama's "accident" of fire at Hajime (before he learning it wasn't an accident by Hajime's enlightenment). He was easily manipulated by Eri's "shy" personality just so she used his weaknesses towards him. In his doppelganger's temptation, Kouki was easily to be foolish when he was corrupted by his own doppelganger's deceptions of Hajime "brainwashed" his harem and Shizuku to become his lovers and condemned Hajime for killing Hiyama despite the latter was a traitor.

While persistently believed he is stronger than Hajime due to being blessed as a "Hero", Kouki foolishly challenged Hajime into an unarmed duel for his harem only for Hajime defeated and humiliated Kouki very easily to ended such a pointless duel. Due to his naivety and stupidity, he would get mad at Hajime and won't believe him that Ehit was actually an evil false god who manipulated humanity and protecting humans from Garland was just a setup by Ehit which is the reason Hajime decided to not tell Kouki for his ignorance that his empty idealism of classmates always obliges to help and protect each other which are the numerous weaknesses for other classmates' possibilities for betrayals such as when being betrayed by the intelligent, Eri Nakamura and the traitorous moron, Daisuke Hiyama (before Eri betrayed him) without even noticing. Even when travelling with Hajime, Kouki continually enforcing these delusions towards Hajime and his lovers even when he foolishly believed Hajime has "brainwashed" his harem and Shizuku to become his lovers (which he never did such a thing) and attempted to kill Hajime and claim his harem to join him to "save the world" on behalf of Ehit only to be easily defeated by Hajime yet again.
