I reincarnated into a crossover world, and the System only activated after eighteen years.
In this world, all the familiar anime characters have become Hunters.
Hunters grow stronger by conquering dungeons.
Kasuga Yu, whose aptitude was only 9, had no chance of becoming a Hunter. But after the System activated...
From the start, he drew an UR card: Tornado!
He randomly obtained a skill: Psychic Storm!
He unlocked an AFK map: One-Punch Man!
[AFK battle complete. Ancient King defeated. Obtained 288,000 EXP, 2,000 Advancement Stones, 800 Breakthrough Stones, 80 Awakening Stones, 8 D-Rank Energy Crystals, 8 C-Rank Energy Crystals, 2 B-Rank Energy Crystals, 3 B-Rank Equipment pieces.]
Kasuga Yu: "It's so nice getting stronger just by going AFK. I can even take a look at the bashful... Huh?! This is actually happening!"
