As a transmigrator, An Ran was filled with a deep sense of melancholy. Not only had he transmigrated to a chaotic world where sexism was so pervasive that even boxers would have to admit defeat, but his cheat codes were also entirely composed of inherited, outdated code, offering a free door-opening and killing service. Disbot bumped into Altosh, a broken cup got smeared in the face by the bug lord, Teyvat collided with the heavens... Life was tough. To survive, An Ran could only become a man who was either getting stronger or on his way to becoming stronger.

On the day of my car accident, something strange popped into my head!!! Yukinoshita Yukino: Hikigaya-san, stop what you're doing or I'll call the police. Yuigahama Yui: Hikigaya, you're actually doing this to me!!! Kato Megumi: Hachiman-kun, this isn't okay~ Kasumigaoka Utaha: Junior, you can't do that. Sawamura Spencer Eriri: I treat you like a geek, and you're trying to do all this to me... Aoyama Nanami: Impure relationships with the opposite sex, no! Shiina Mashiro: Hachiman, you're my first... Hikigaya Hachiman: It's all the system's fault!!!
