The time-traveler Hanyu Tsuru brings an all-in-one skill system to the world of comprehensive comics that combines spring objects, passerby heroines, and lonely rock, and meets Kato Megumi, who is in the same class. He relies on the system to improve his abilities, and relies on plot knowledge to protect Kato Megumi and break her transparent physique. He joined the service club, met Hikigaya Hachiman and others, came into contact with the Toyosaki Game Production Department, and met Goto Kazuri and his band members in Shimokitazawa. He warmed everyone as he grew up, and went in both directions with Kato Megumi, writing about healing youth.
