I've decided to start this! There are way too few ShinNobu fanfics... Time to cook!
Saburo, an ordinary high school student with no interest in history, slipped and fell into the Sengoku era, where he was forced to become Oda Nobunaga. Just as his life as Nobunaga was about to end with his death in the Honnoji Incident, he slipped again and somehow made it back to the present, where he could resume his high school life. That was what he planned, anyway.
But here's what actually happened:
Day 1 after returning: A strange fox showed up at his door and asked him to become a saniwa. He refused, then slipped and fell straight into a place called a Dark Honmaru, where he started his daily grind.
Day 10 after returning: He unlocked the achievement for purifying every corrupted sword.
Day 23 after returning: Why have all the worlds fused together?!
Day n after returning: This is all Aida's fault, isn't it?
