Anime Crossover: My Little Sister Is Shiro, and I'm the Strongest Player in the Death Game

After transmigrating to a crossover anime world, Nangong Yu adopts a genius girl named Bai, who is not related to him by blood!

He also awakens a gaming plugin System!

Since the System only works in competitive video games, the siblings become recognized as the strongest players in the gaming world!

However...

One day!

Death games arrive!

The System finally proves useful for what it was originally meant to do!

First instance: Zombie Horde

Yukino Yukinoshita: “Yu-chan, give me the AK with infinite ammo. What will you use?”

Nangong Yu: “Anything will do for me. Heavy Bunny Ried, on!”

Second instance: King's Game

Bai: “Bro... we have to follow the rules, but I don't want to kiss that fat pig.”

Nangong Yu: “Dear little sister, someone dies in every round. Let's use them as cannon fodder and kill them off. That way, no matter what new rules come up, your big brother will help you.”
