[Crossover] The Superpower Series Protagonist Only Wants to Be a Bystander

[On indefinite hiatus] [I'm taking part in an event, so please shower me with votes and comments w] Before my identity is exposed, I'm the arranged-marriage partner and human shield of the Black X mafia boss / an unremarkable subordinate of the Lord of Monsters / an ordinary, Quirkless student in a superpowered society. After my identity is exposed, I'm the strongest in the world. A simple introduction: I'm the protagonist of a superpower series. Not only can I transmigrate through time and space, I also try to pass myself off as an ordinary passerby in every era, hoping to live an ordinary life. But things never go as planned. My identity gets exposed. So long! In a nutshell: The protagonist is a big shot who only wants to coast, but gets found out and ends up falling in love. To expand on the title: Though I'm the protagonist of a superpower series, I only want to be a passerby XD My other works: "[Segawa] Forced to Fall in Love [Crossover]" If I don't fall in love, I'll die. What can I do? :) "Unconventional Hero Izuku Midoriya [Crossover]" Izuku Midoriya: My wish is for world peace. "The Demon King's Zero-to-One Life in the Real World" Don't say a word. Save first!
