After mustering up the courage to propose to a girl in an online game, naive otaku Hideki Rusian Nishimura is devastated when she flat-out rejects him. To make matters worse, the girl reveals that she is actually an older man in real life. With his dreams crushed and his heart broken, Rusian comes to an abrupt decision in the midst of his raging fit: he will never trust another girl in an online game again.

However, after a discussion between the guild members that led to all of them having an offline meeting, Rusian finds out that Ako, along with the other members, is not just a girl but also his schoolmate.

During Japan's feudal era, there was a war between two ninja clans: the Byakuro and the Kabusu. One night, the Kabusu staged a fierce attack on the Byakuro castle in hopes of kidnapping the clan's infant princess. Their mission was foiled when a loyal ninja of the Byakuro flees the attack with the princess and disappears, eventually raising her to be a ninja. Several years later, six ninja trainees are given a mission to infiltrate the Kabusu-occupied Byakuro castle and retrieve a sacred scroll to complete their training. But their skills are put to the test when they encounter three members of the Kabusu, who use dark sorcery in an attempt to once again capture the princess - who happens to be one of the trainees.
