Oh btw, according to Wikipedia (at the moment!) he's actually a Nekomata with the two tails and the other abilities (not giving apoilers), instead of a Bakeneko who have one tail, dance, drink lamp oil and wear scarves/ bandana on their heads 🤣.

I wonder what course told you the opposite....the wiki's are pretty well source material-ed, even if they can be unreadable for one reason or another.
Btw, seeing the "happy monster" ending he's actually a NekoNaga (for those in the know about Naga anatomy 😉 & not giving away obvious spoilers 😋).
