General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

I spent my life playing a game.
I hit the wall, stuck in second place for the rest of my life.

Out of the blue, I received a message and was possessed by the game.
As the worthless son of an Underworld Boss!

“Yes, bloodline is also a power, as long as you can use it. My ability is ‘Famiglia’.”

The game addict never disappears. Overwhelming violence, endless wealth, connections in the other world. I, I’ll use anything to stay alive!
