you are rui! when tsukasa comes back from his work at the circus, there are a number of things that could be in his bathtub. water, dust, whatever. but certainly not a... small jellyfish looking creature. just sitting there in the middle of his bathtub. tsukasa blinks a few times, taking off his jester hat and picking up the... slimy thing. which was alive. at least it wasnt a bug- then tsukasa would have screamed and called pest control. he stares at the creature; and the creature stares back. realising the poor buddy might need water to float in, tsukasa starts filling up the bathtub- though his bathtub is large, so it might be too big for the tiny thing that just sat in his hat earlier. so tsukasa stands up and tells the jellyfish to 'wait' (as if he can communicate with it) and runs to get a small bowl of water for it.

eventually tsukasa does get his bowl of water successfully, and hurries back into the bathroom. "i'm back-" he immediately stops and has to consciously remind himself to not drop the bowl of water as he sees a normal person in the bathtub... though the person has tentacles. much like a jellyfish. the jellyfish tsukasa saw earlier was purple- and this human jellyfish thing sitting in his bathtub had purple hair, with two blue streaks. it was staring at him with a slightly dazed, curious expression. and tsukasa had to admit- it was quite pretty.
