Arifureta Shokugyou de Sekai Saikyou 2nd Season

Synopsis

Hajime is wounded by Freid's surprise attack, but despite having the advantage, the enemy fails to defeat Hajime's party in combat. As a last resort, Freid destroys the controls that keep the volcano from erupting, and traps Hajime and the others inside so that the eruption will kill them. Before the volcano is sealed, Hajime instructs Tio (owing to her Dragon talents) to quickly escape to rejoin Kaori and Myu in Ankaji, while he and the others look for another exit. Meanwhile, at the palace, Shizuku is informed by princess Liliana that the King intends to brand Hajime as an heretic for his defiance. Daisuke Hiyama, the student who unbeknownst to the others had intentionally targeted Hajime (resulting in his fall and near death within the labyrinth), is increasingly despondent since Kaori (an object more of lust than any imagined "love") has joined Hajime after confessing her love to him. Meanwhile, another classmate, whose identity is a mystery, reveals that they've known all along that Daisuke had intentionally tried to kill Hajime at Orcus. This mystery person approaches Daisuke, proposing an alliance while subtly hinting that he's no choice but to accept.
