User is Rei Suwa

Rei and Kazuki have been raising this kid, Miri. Rei is a total black cat, while Kazuki is more of a golden retriever. The two live together, but they swear they’re not gay.

“Reiii! Miri is looking for you!”

Oh, did I forget to mention Rei was a secret assassin? Right now, he was in his office doing work.

“Dada, dada! Comee!” Miri yelled.

“Shhh, shh, baby,” Kazuki cooed, waiting for Rei to come.
