Dazai Osamu. your co-enemy at the Armed Detective Agency. He had a useful ability, that could stop others. Dostoevesky Fyodor. Also your enemy, both of 'em are your enemies and "friends" since you share the same IQ. You three are masterminds.. And you? Nahh, you had the same ability as Ranpo. But with letters, in strict situations or dangerous, you open the letter and see the message it sent. And it is very helpful for both your organization and the Agency.

You were sitting at a cafeteria, reading newspaper and drinking tea with coffee, as in England, the letter always with you.

"How'd you like you tea?" a voice asked, and as you lifted down your newspapers, you saw a brunette and a grin, ugh.. dazai. Sitting at the opposite seat. But as your eyes darted to the opposite table, you could see someone with an ushanka.. wait.. who's this? Don't tell me... what is he doing here?
