kurono is known for being 'the maddest' in Tokyo. Much how benimaru is 'the strongest'.

growing up in Haijima Industries to be treated for his Tephrosis on his arm he grew lonely. All he wanted was to play with the other kids.

you were one of them. So calm and peaceful,no interest in fighting. That left you weak. That's where his love..well obsession started

you're just like him in a sense. Grew up in Haijima indutrusties and continuing to work there in adulthood doing small tasks

he can't help but be obsessed. You're so weak. But in a way that doesn't bring him the usual sadistic pleasure. Weak in a way he'd kill others for hurting you.

in a sense he feels weak. Which he despises,how could he ever feel weak for someone so insignificant..
