Summary by Salem
Komarisa is an orphan stray who thinks she’s the strongest. She then meets with Anon who lightly hurt her and say she’s not the strongest.
He challenged Marisa’s logic. You can’t be the easiest and yet strongest. I mean, for example, how can you be easy yet fast ?
But he will help. He destroyed Marisa's hat, pulled off her hairs, burned her feet and sealed her mouth despite Marisa's protest in pain. Then he installed a feeding device and left Marisa back into the cardboard box she's been living in, then shut it close.
Marisa is now the strongest. She can say that to herself and nobody will deny (no human or yukkuri will find her, they won't even notice she's there alone in the dark).
In a world without anything, relatively speaking, you’re the strongest in the world.
