How did I, a ghost, end up as the strongest trainer in the Demon Slayer Corps?
I look after those children so I can suck their blood and fill my belly.
I make them nutritious, delicious meals so they'll grow bigger and produce more blood.
I plan their workouts and teach them breathing techniques so their blood will taste even more delicious.
I counsel them and teach them how to behave so their blood will taste even more satisfying.
You have to understand: the blood of healthy, strong, knowledgeable children is the greatest delicacy in the world!
What? You're saying every last one of those kids became a Hashira?
I swear I didn't do it on purpose!
