Superstar From Age 0 - Chapter 458:

Out of the blue, I received a message and was possessed by the game.

“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!

I am the most talented guardian of this era!

You may have seen the meatless juggernaut, but you have never seen a full-time meat shield with an explosive attack!
