An ordinary college freshman died suddenly while playing Senren Banka, then transmigrated into the role of Giyu Tomioka during the battle in the Infinity Castle. His Demon Slayer Mark had already appeared, which meant he would die at twenty-five. But then the System came looking for him.
System: “Hey, kid, how about making a contract with me and becoming a magical girl? Just kidding.”
To avoid dying young, he was forced to set out on a journey.
Note: The author is only at an average high school level and isn’t a good writer. I’m writing purely out of love for the series. Since I’m still in school, updates will be irregular. There’s one female lead, though you can also treat it as having no female lead.
