地獄楽 11 [Jigokuraku 11] by Yūji Kaku

As the hunt for the island’s legendary elixir intensifies, the group’s tenuous alliances are strained by brutal new revelations and relentless, monstrous threats; the protagonist and his executioner partner are pushed to their limits as they confront both external enemies and the ghosts of their own pasts. Loyalties are tested, betrayals surface, and desperate battles force painful choices that redefine who can be trusted and what survival — or immortality — is worth. The volume heightens emotional stakes and sets up pivotal confrontations that will determine the fate of the surviving cast.
