[Your name isn't that awful string of numbers. You're my little brother, Asaba Akira.]
A few years ago, he escaped that lightless place with his older sister, but they got separated.
One went south, the other north.
His sister went south, and without any way to contact him, she's been missing ever since.
He went north and was lucky enough to be taken in by an old beggar, traveling from place to place with him.
Now he was ready to find his sister, who was far away in the south.
His first stop: Yokohama.
Asaba Akira's older sister, Asaba Ren, is a very strange person.
She's always searching for something. That's why she joined the Mafia while the old boss was still alive, left a file with the Special Division for Unusual Powers, and even crossed paths with the Rats in the House of the Dead.
In the end, all the investigation turned up was the word "missing."
Asaba Akira swore he was only here to find someone.
He absolutely didn't want to join the Mafia, the Armed Detective Agency, or the Rats in the House of the Dead!
Chuuya, stop trying to drag me out for drinks! I just took cefaclor!
And Dazai Osamu, would you stop trying to get me to test out new ways to kill myself? I don't want to know about any of that.
Damn it, you rat, you mistook me for someone else again! I'm not my sister! I'm looking for her too! Even if I find her, I won't hand her over to you!
If I hadn't been young and impulsive enough to let the Mafia fool me, maybe I'd still be happily looking for my sister instead of working a soul-crushing 996 schedule for the Mafia.
Asaba Akira: ...I'm so numb.
