The last time Dazai kisses Chuuya is at the end of the world, Corruption unleashed in all its power, Chuuya's head thrown back in laughter. Red light paints Yokohama with destructive glow.
It's beautiful, terrifying, perfect—a double suicide neither of them had planned but neither regret.
Because destruction can save, and they're stopping the end of the world. This is for everyone else, one last sacrifice.
The last moments are theirs, Dazai tasting the blood of Corruption in his mouth as he holds Chuuya and sees the light in his eyes one last time before everything crumbles to dust.
