Magical★Explorer

Magical★Explorer summary:

There’s a legendary Bishoujo Game that has become popular among j.a.panese 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 h.e.l.l out of that cheat who can solo the Demon King.
………..I was training with that thought in mind, but somehow I keep getting closer to the heroines and furthermore, I don’t know why I keep encounter events like I am some Eroge’s protagonist.
