"You keep fish?" Kotetsu felt a flare of something - maybe it was recognition, maybe it was hope, but it died. Ginta sounded like someone who really loved fish as a hobby, bred them for show even, while Kotetsu had only just found out that something was eating his betta's fins. He hoped Ryuichi'd change the water like he'd promised. Or else Green Demon might die.

"I only had him for a bit," Kotetsu ventured, wondering if Ginta'd take the opportunity to talk about himself, or try to pry things out from Kotetsu, or leap like quick-silver onto another subject. What, maybe it'd be birds? Wood? He liked hearing Ginta talk, and he gathered that Ginta was terribly clever, but it was disconcerting all in all.
