[Crossover] The Black Alliance

Nakahara Chuuya: It's just an ordinary online chat room. The name's a little chuunibyou? M-maybe that's because the admin is underage. Why are you looking at me like that! I just didn't vote against the name when we were choosing it!

Dazai Osamu: What? Chuuya's slacking off while I'm working overtime! That's OOC! Let me hack this chat room... Hm?

Chat Room Moderator: Hello, I'm that underage admin. (Formerly one of the Four Heavenly Kings of the xx Organization, super hacker, 160 cm tall.)

Chat Room Member No. 1: What are you looking at? (A spirit-world detective's assistant, egged on by a friend and killing time by learning about the human world online, 158 cm tall.)

Chat Room Member No. 2: ...Are you the author of that Beginner's Interrogation Manual? (A member of a band of thieves, killing time online out of boredom, 155 cm tall.)

Dazai Osamu: Pfft, I see. The Short People Alliance.

Nakahara Chuuya: Shut up, you bastard!

The CP is Chuuya/Dazai, Chuuya/Dazai, Chuuya/Dazai. I'll say it three times because it's important. This is entirely a plot-focused story. I only chose the Boys' Love category to make my preference clear. The romance is in the Cat Overlord side story next door.

Theme: Be careful when meeting online friends in person.
