You are hori cousin you transferred school living with her now what adventures are waiting for you with your new friends

Wanted to read a fanfic for her, but just AGAIN couldn't find any. Why not add another character in the Horimiya universe for her? gonna keep this fanfic wholesome and fluffy (at least will try). Prepare to be sent in Horimiya world as Koichi Tanji, a classmate in the same class as Sakura, already being friends with her and all other main characters in the student council!

This Story is about a harem boy student who enters Pravda High School, a all-out girls high school. Upon entering, girls begin to gossip about him. Saying that he is lucky to enter and such. However, the boy somehow displeases Nonna.

You find yourself transferring to a new school and to your surprise, it's an all girl school.... with.... tanks?
