Secretive - Kuboyasu Aren X Assassin OC

I don't own any of these characters except for my OC. The rest of the characters belong to Asou Shuuichi, Kazutaka Kodaka, and Sakae Esuno.

I made this an OC because I'm too much of a wuss to make it x reader. It can still be an x reader if you aspire to be an assassin though.

Reasons to read this:
1. This story is my first ever because I'm still practicing.
2. There will be appearances of Danganronpa characters. Yes! Danganronpa characters!
3. Character is an assassin.
4. It's Kuboyasu Aren.
5. It's romance + action, what more could you ask for?

Onto the description.

It's Tomoshi Yuuko's first day at PK Academy, and she already sees very interesting people. Her goal is simple. Study hard, conceal who she really is, and graduate. No more no less. But with Saiki's gang, can she really achieve this so easily? Especially with Kuboyasu around?

Small rant WITH SPOILERS:

why did it include a mafia smh
