I believe so! It’ll be hard to know until the next chapter is out though, tsukasa was probably replaced with a yokai (which would be the one amane killed) claiming to be tsukasa, another theory I had that’s a bit of a stretch, the tsukasa amane killed could’ve been manifested from hanakos subconscious guilt of tsukasa sacrificing himself! The real tsukasa is the younger one (also yes baby tsukasa protection squad)
And it would make sense that hanako would feel guilty that it killed the ghost because it looked like tsukasa and I bet the ghost mentally and physically abused hanako
Soooooo did a ghost replace tsukasa after that and terrorized everyone cause likeeeee this just showed tsukasa is bby boi and must be protected
