I'm a teacher in Tokyo!

Chen Zhen transmigrated and became a teacher named Yoshizaki Kawa at a Japanese school.
At first, he thought it was normal.
Until he discovered that the girl who was bullied by the original owner of the house and came to collect rent every month was named Kayako.
Furthermore, a classmate named Tomie in university was secretly flirting with him.
There's also a neighbor named Shirai, an autistic girl who doesn't like people calling her by her name.
There was also a transfer student named Sadako Yamamura who came to him one day to apply for a scholarship.
He fell into deep thought;
Since things are already like this, might as well go all out.
"Kayako, Tomie, Sadako, let's play Ouija!"
Yotsuya Miko: “???”
