Mikasa decapitates Eren, admits her feelings for him, and kisses the severed head of the adopted brother she killed. She then marries Jean the simp. In some epilogue panels, it’s revealed Eren had a ♥♥♥♥ plan as a bombing raid commenced on a city on Paradis island with modern surface to air missile batteries in the foreground, followed by a kid running through the city’s ruins. I.e. decades into the future and the world still wants the Eldians dead. The end. Isayama had an acid trip.

Demon Slayer gets carried by its animation. Every upper moon fight involves Tanjiro magically getting a power up. When the demon gets decapitated, they will themselves to continue to live, but then they remember when they were human, get sad, and decide to die. The final Muzan fight is garbage.
