Young master Gene had escaped his family's infighting and was living happily in Yokohama, Japan, with his current guardian, Hobart.
Then one day, his guardian brought home a strange young boy who radiated world-weariness, and showed him a great deal of affection.
Gene (biting a handkerchief): I've been strictly trained. I'm not jealous at all, and I've decided to get along peacefully with my new friend.
Dazai Osamu: ...Okay.
Once their fake brotherly bond turned into genuine affection, Dazai Osamu urged his friend to go back and fight for the family fortune.
Gene (convinced): All right, I'll go. Take care of my guardian for me.
Dazai Osamu: Don't worry!
And then the guardian was gone.
Dazai Osamu: ...
Later, Dazai Osamu learned that his friend was gone too.
Dazai Osamu: ...Let's just destroy everything.

When Gene returned to Yokohama, he discovered that his guardian was gone, and his sweet, innocent friend had turned into a grotesque mass of black sludge. He'd even joined the underworld and was working for a heitai lolicon.
Gene: ...Let's just destroy everything.
