What do you think Haruji would be able to do for it, huh? He can't shrink alien fish! Just put it back into the tank.

[Kashuu isn't signing any waivers though, nope, nuh-uh, he's had enough brushes with death over the last week and he's not taking any risks. If Fishy looks like he's going to take a chomp out of one of them, Kashuu's abandoning ship...]

Or... I dunno, bring the tank over here and we can carry it back!

[As if that won't weigh like 100000 pounds...]
