It was very easy to tell this author was going to have process.
There is no real ending to this manga, either the world gets re-created into someone twisted vision or via future time skip, or both MCs fall into the demon world, the girl turns into a motocycle (herself flipped up with two wheels instead of hands and feet), and then they ride together towards some sort of shogun castle or a fortress. For real.
The motorcycle-girl makes me lend to think is someone twisted vision, I think they mess up in the final battle.
