Using Video Game Expertise to Live a Joyful Life After Sacrificing Myself for the Protagonist

In the world of the popular RPG game called Star Brave Fantasy, I was reincarnated as a character who is a close friend and sacrifices himself to save the protagonist.

Ten years later, the event of death awaits – in preparation for the day of destiny, I begin to strive to obtain power and pawns that will become my strength and limbs.

And so my school life begins. I try to build extremely tenuous human relationships, keeping a certain distance from the protagonist so as never to become his close friend. All this in order to escape the death event and find a way to survive, using all my knowledge of the game to reach a happy ending.
