[Western Crossover] Aha Insists I'm Their Biological Child

This novel will enter VIP status with Chapter 20 on Tuesday, June 16! There will be ten thousand words that day. Thanks for your support! Yun Zhao had always known that her “guardian” wasn’t quite right. They were called Aha. In her eyes, Aha always looked the same: a red smiling mask, a black veil, and a theatrical, deranged, mysterious “woman.” But to everyone else, Aha had countless faces. They could be anyone. During the summer of her sixteenth year, Yun Zhao suddenly received a paternity test. According to the results, her father was Gotham’s richest man. By day, he was a billionaire; by night, a vigilante protecting Gotham. Yun Zhao, who had just read some Batman and Robin comics: … Aha was still cheerfully making suggestions. “Bat-kid stories are all the rage lately, darling. Why not go to Gotham and meet your father? Be fashionable.” Yun Zhao: “Is this test real?” Aha covered their mouth and chuckled, their tone playful and delighted. “If you believe it is, then it can be real.” Yun Zhao wasn’t particularly interested in this “father.” Aha might not be reliable, but they had never let her go without food or clothing, and she felt she had no shortage of love. She was just suddenly curious. “Then who’s my mother?” At that, Aha instantly looked ready to burst into tears. They pulled a handkerchief out of thin air and dabbed at the corners of their eyes. “Darling, how can you say something like that? You’re breaking your mother’s heart. Of course I’m your biological parent.” Yun Zhao: “…” Unable to put up with Aha’s pestering any longer, Yun Zhao finally boarded a plane to Gotham, only to be caught in a hijacking. And then a livestream began. Ding-dong! Phantasmoon Games: Gotham Edition is about to begin. Welcome to the livestream of the chosen Emissary of [Aha]!

Hurry into the room [Due to certain controversies, the original Detective Conan crossover setting has been changed to a DC/Marvel crossover. I don’t plan to write Japanese anime crossovers in the near future (I’ve had enough of the landmines). Other livestream elements and the Genshin Impact, Honkai: Star Rail, and FGO-related settings remain unchanged.] Reader’s Guide: 1. This is more or less a sequel to my Genshin Impact and Honkai: Star Rail works next door. I’ll do my best to make it understandable even if you haven’t read them. 2. Timeline: Honkai: Star Rail version 4.0, at the beginning of Genshin Impact’s Song of the Welkin Moon. I won’t specify the FGO timeline because that would involve spoilers. 3. Phantasmoon Games and the Holy Grail War take place simultaneously, one in plain sight and one in secret. 4. Thanks to [Elation]’s unique ability to break the fourth wall, the protagonist knows the Bat-family’s identities from the start, but pretends not to. 5. The heroine is a behind-the-scenes mastermind who even schemes against herself, but knows how to keep up appearances. 6. No romance. High school students from China can save the world, but they can’t date. 7. Not friendly to villains like the Joker. 8. More to come. Blurb revised and screenshotted on March 12, 2026. Theme: Saving yourself is saving the world.
