[Immediately and wish almost practiced ease, Karamatsu lifts all four hands in defense, taking a slow step back and away from Spike to put even more space between them.]

Please...try to be calm. I am not going to hurt you. I am not the only monster here at present, and I cannot say for certain all of them will be willing to defend you, so try to keep your voice down.

[Not that Karamatsu knows the mermaids that keep appearing everywhere aren't...exactly permanently like that.]
