Synopsis
As a college student who has no dreams, no future, and no girlfriend, I was on the verge of repeating a year, and I spent all my part-time work on my smartphone, and only Gacha lived a worthwhile life.

At university, I met Sayuki Sonomura, a young lady from the former Kazoku family. He had a secret. He was a more abandoned gamer than I was, standing as my rival in every smartphone game! I can't forgive a young lady who was born blessed to step into my abandoned billing path, and I can't lose!
