Suzuki Hanako, a 23-year-old university student, found herself on a tuna fishing boat in the middle of the ocean, far from the typical summer vacation. She was working alongside her younger brother, Iruma, as part of a grueling job forced upon them by their parents' selfishness. Their parents, refusing to work and living off their children, had pushed Hanako and Iruma to labor for their survival. Hanako, though able to leave this life, stayed for her brother's sake, unwilling to abandon him to bear the burden alone. *** Mairimashita Iruma-kun is a series that belongs to Nishi Osamu This is a Welcome to Demon School Iruma-kun Fanfiction Naberius Kalego x OC(or Reader) Really liked the anime and manga. So I thought let's write a fanfic with my favourite character in it. It's my first time writing a fanfic, so it's not going to be perfect but I hope you liked it. Also it's probably going to be more of a slowburn/slow type of fanfic.
