Magical★Explorer - Reborn As A Side Character In A Fantasy Dating Sim

There’s a legendary Bishoujo Game that has become popular among Japanese gentlemen. Its name is “ Magical★Explorer” or Magiero for short. The game’s protagonist has a cheat-like power with12 different beautiful heroines to flirt with, including additional 12 heroines from the DLC, a harem of 24 beauties. I have become that protagonist!………………Not. Instead, I have become the third-wheel character who always laughing like an idiot next to him. Of course I was in despair at first. Of course. If I am the protagonist I could have all 24 heroines for myself along with unparalleled cheat power. However, since I am the third-wheel there’s no heroine that would lay their eyes on me. But now I couldn’t care less about the protagonist and his heroines. Why? Because I discovered magic. While I was using it, I have become interested in it. I want to master it. I want to become the strongest. Thus I have decided. I would abandon half my role as a protagonist’s friend to train my magic and then I would beat the hell out of that cheat who can solo the Demon King.
