How Well Does the Gravity Manipulator Fit in Gotham?

[The next story, The Port Mafia Gravity User Transmigrates Online, is now underway] Blurb: During an accident, the Port Mafia's gravity user found himself in a strange world, along with a deluxe package deal: amnesia and a shrunken body. Amnesiac, little Chuuya began his life in another world. But all sorts of strange people kept showing up in front of him, disrupting his plans. For example: The blue robin: "Chuuya, Chuuya, want to be my partner?" Chuuya: "I refuse." The pitch-black bat: "You should go to school." The King of Sheep: "Not a chance." A certain lunatic villain: "If I broke your wings, the little bat would be so angry, wouldn't he~" The gravity user: "Are you trying to fight gravity? I'll crush you!" And the cast just keeps growing... Chuuya only wanted to live a quiet life and recover his memories, but today, as usual, he was especially irritable. *This novel will be going premium on October 31.

And so... The future boss of a certain mafia family gained a dual-purpose tutor in martial arts and academics; a certain strongest sorcerer nearly exorcised a human who seemed to be a special-grade cursed spirit; and a savage god awakened from slumber appeared in Hachiyo... Chuuya had always thought the bonds he'd formed in those other worlds would eventually fade into memories. But one day, he discovered that the worlds he'd visited had merged. Strange-looking cursed spirits began appearing on the streets of Yokohama, the Port Mafia suddenly gained an Italian business partner, and even the companions he thought he would never see again came looking for him. It would be even better, though, if a certain white-haired strongest sorcerer didn't make such a huge spectacle of pursuing him. Chuuya couldn't help tugging down the brim of his hat. His orange hair hid the tips of his ears, now red with embarrassment. "Keep it down, you idiot!" Theme: No matter where they are, diamonds always shine.
