dazai and fyodor were playing chess together, talking in their forbidden language to communicate as they both have higher IQ’s to do so.

Fyodor: “ah, people who have the same IQ or higher can understand us, or maybe even join in, right dazai?” the russian terrorist spoke.

Dazai: “of course, indeed.” dazai chuckled, “check mate.”

the two of them were prison, locked up in secured circle like cells, as they are ability users.
