It is uncommon for an exorcist to let a supernatural go, especially when it comes to someone as great and talented as Minamoto Teru himself. that's why when Kou, Nene, and Hanako found out they thought he got brainwashed but he didn't.
Hanako suggested to them that it might be a dangerous supernatural event if they can brainwash humans and any others, and that's how all three of them are on the place where Teru met y/n.
They expected an evil apparition with a scary place, scary aura and scary face but instead they met with a gorgeous, magnificent, wonderful, handsome and caring one. they were confused yes but they immediately warms up to y/n.
"okay wait! what kind of an spirit are you?'' Although Kou's question is somewhat harsh but he was curious, he earns a worriedsome look from both Nene and Hanako. "Hmm.. why don't you find out yourself, Minamoto kid." the way y/n mocks him doesn't even feel like it's a mock.
"wow, y/n you're really.. pretty and.." Nene grabs on y/n sleeves, y/n was sceptical the way she can easily touch but let her be anyway. "How are you so attractive!?" Okay now she is just screaming at the poor spirit.
"calm down Yashiro.'' Thank you Hanako. y/n thought that this trio is funny and silly, despite them being completely different from each other. "Yashiro? What an interesting name." y/n mused. Nene easily blushed at the attention.
"So y/n-san what's your power or what kind of apparition are you?" the question is brought once again, although y/n already said to them to find it out themself. y/n sighed.
"come here.'' All three of them thought the spirit called them when suddenly a pure white cat appeared suddenly on y/n's shoulder, it let out a tiny meow. "A CAT !?" all three shouted. now they're even more interested in y/n. a cat spirit? how interesting.. is what hanako thought by the way.
"I much rather sleep here than let myself have a rumour and people getting interested or searching if it's true or not." spoken like a true cat, may y/n is a cat from heart. maybe.
"y/n-san don't you have a rumour?"
y/n shrug.
"I dunno, not that I care of course." The way y/n just lay back down on the branch and proceeded to sleep is amazing. the cat lay on y/n's stomach and slept there.
"wow.. you're actually acting like a cat.."
