One day, while attending school with Ki, Keika encounters a young woman at the university who is able to see him and seems interested in being friends. She has a passion for teaching, but her lessons are not going well and she is struggling to gain the respect of her students. However, Ki suspects the woman has a very different reason for pursuing a frienship with Keika.
Don't make me angry.

No me hagas enfadar.
Ahora soy invencible.
Faut pas m’énerver.
Désormais, je suis invincible.
Non farmi arrabbiare.
Ora sono assolutamente invincibile.
Não me irrite, eu sou invencível agora.
