My Ability Is a Character Sheet, and It Comes from Arknights

Chen Zhou transmigrated here eighteen years ago, bringing along an Arknights System that could draw cards and equip him with character profiles, but he had never unlocked it. Apart from the fact that both his parents were dead, his life had been peaceful: he went to school without a hitch, and nothing ever happened. It seemed like a perfectly normal world. Then, on his way home after picking up his high school admission letter, he accidentally entered the Otherworld, a forbidden zone for the living. The subway train across from him slowed to a stop, and countless eerie, terrifying creatures emerged. The System, dormant for eighteen years, finally stirred.

[First entry into the Otherworld: 1 Recruitment attempt gained]

[First encounter with an Otherworld creature: 1 Recruitment Permit gained]

[Congratulations, you have touched the truth of the world: 2 Recruitment Permits gained]

[A corner of the world's iceberg is beginning to unfold before you. Prepare yourself for the storm ahead! Limited Newcomer Recruitment is now open!]

With monsters in pursuit behind him and his legs nearing their limit, he said, "At this point, I might as well draw some cards first."
