Shadow stood and was already exhausted after fighting a level 100 monster. Suddenly, a glow appeared out of nowhere.

"What... finally... finally... those NPC twins!"

The glow disappeared and two children appeared, seemingly 8 years old, twins.

System : User Shadow received level 100 assistants. Congratulations.

Twin sister: "Hello! My name is Niya! I'm a twin sister."

Then she looked at her twin brother, you.
