King of Gacha

Ryuuki has been betrayed by the people he trusted and has fallen to the lowest ranks of society. Hoping for his luck to turn for the better, he spends his days playing at the "Randombox". His aim is the SSR-rank reward, the right to make an account for the game "Labyrinth"! Sadly, not only did he actually manage to pull his greatest wish, but that too got stolen from him. However, that's when Ryuuchi's true luck started! "As long as you can pull it, you will be able to use The System and defy all logic". Everything stolen from me... But I will take it all back through Gacha!!
