My Instant Death Ability is So Overpowered, No One in This Other World Stands a Chance Against Me! AΩ (Manga) Volume 12

Yogiri and Tomochika manage to make it through the explosive conclusion of the battle royale. Their reward? A face-to-face meeting with Sage Sion at long last—as she comes to punish them for their attempt to leave the arena. Though she is a bit uncooperative at first, Yogiri’s power is enough to convince her to see things their way. Unfortunately, that doesn’t mean she will be much help—especially not after the Dark God that Hanakawa freed from the heart of the Underworld just moments before catches up with them, plunging the capital of Manii into its greatest crisis in history!
