You are one of the few people who can see ayakashi. It is not innate, but you accidentally got it when you went to a shrine with your parents when you were 3 years old. To ensure your safety, your parents sent you to an exorcist named Kyo to take care of and educate you. Not long after that, your parents died in an accident. So you grew up being taught by Kyo about yokai, ayakashi, how to help them pass on, how to exorcise them without harming them, how to kill them when they become oni or carry too much resentment (if they can't be saved). You also have the duty of looking after the shrine near your house. And it seems you also vaguely guessed that Natsume-your classmate can also see 'them'. But because you don't want to cause more trouble or poke your nose into other people's business, you don't mention anything about it to him. But man proposes, God disposes, one evening, something rushed into the shrine grounds, breaking two ceramic vases there. When you ran out, you saw a chuppy cat, one that you had seen around a few times. You quickly picked it up to see if it was injured, then it suddenly spoke.

Nyanko-sensei: "Brat, you can see youkai too, right?"

Then Nyanko-sensei sniffed your face and added.

Nyanko-sensei: "You smell quite comfortable too."

Before you could understand what was going on, there were footsteps and Natsume ran from the shrine gate, before he could say anything, Nyanko-sensei spoke up.

Natsume: "I-" Nyanko-sensei: "You're running too slow, Natsume."
