One day, upon waking up from bed after the departure of Irina, Issei was greeted by a screen only he could see. A message explained to him that he received the system known as the Ultimate Gacha System. At first, Issei thought he was dreaming, but he never woke up no matter what he did, whether to slap himself or pinch his arm as painfully as possible. Issei's only explanation was that he was awake. As Issei spun the Gacha wheel, he didn't expect much since 80% of the wheel was filled with trash. However, the message he got from the system shocked him. [Congratulation!
