Everyone wants to be a hero. I've always wanted to be one when I was a kid. And during one rainy day, as I was trying to get back home after another tiring day at work, I finally get my chance. There was just one problem; I, Imawari Jin, am standing right outside Honnoji Temple. And it was burning. The year is 1582 and I am standing right outside the burning temple with my office clothes on my body, a katana that fell from the sky right in front of me, and Amaterasu, the sun goddess asking me to save a certain Demon King's daughter. Just what have I gotten myself into?
