Premise
There is a bishōjo game that has become popular among Japanese gentlemen, named Magical Explorer, or Magiweo for short. The game's protagonist has a cheat-like power with twelve different beautiful heroines to engage with, including additional twelve heroines from the DLC, thus a harem of twenty-four beauties. Kousuke has not become that protagonist. Instead, he has become the third-wheel character who always laughing next to the protagonist. There is no heroine who would look at him.
Kousuke is more focused on his discovery of magic than the protagonist and heroines. He decided to abandon his role as a protagonist's friend to train his magic and become the strongest. Although he is training in order to beat the man who can single-handedly defeat the demon king, he ends up in situations where he develops feelings for the heroines.
In the game, he serves as a supporting character and best friend to the protagonist. He often fulfilled the role of comic relief; hiding the sorrow from his loneliness from having no family at home. The reincarnated version, aware of the game's storyline, wants to become a powerful fighter so he can protect the girls living with him and make them all happy. Because of his low amount of inherent magic, he has trained to use his scarf as a weapon .
