"The Best at Being the Worst" (無能の無双) is the 13th and final episode for Season One of the Arifureta: From Commonplace to World's Strongest Anime adaptation. It aired in Japan on October 7, 2019.

Synopsis
When Hajime's classmates are threatened by a demon mage to "join or die", it's up to him to rescue them-- whether they like his methods or not.

Summary
Hajime sees through Cattleya’s magic and kills all her monsters. Hiyama is terrified at Hajime’s return, fearing he will be discovered as his attempted murderer. Hajime transmutes Shizuku a new indestructible sword. Myu calls Hajime “Papa”, confusing everyone and upsetting Kaori.

Cattleya attempts to flee but is caught by Hajime who tortures her for information, shocking his classmates. Hajime learns a powerful demon has cleared one of the labyrinths and is using its Ancient Magic to create a monster army. Cattleya warns him her lover will kill him in revenge, but Hajime kills her anyway. In the aftermath Kouki is outraged Hajime executed the helpless Cattleya so Hajime berates him in return for being too weak to do what is necessary, warning Kouki if he or any of his classmates try to stop him, he will kill them too.

Kaori confesses she loves Hajime but he turns her down as he already loves Yue. Kaori insists on joining his team anyway to compete with Yue. Shizuku tries to return the sword he gave her but he tells her to keep it, though it is suggested she may be developing a crush on him. As they leave in Hajime’s transmuted SUV Kaori is furious to discover she must share the back seat with Shea and Tio while Yue automatically gets the passenger seat beside Hajime.

Hajime remains determined to make it back to Japan no matter who he has to kill, even God himself.
