I, a Kamen Rider, Teach at Honkai Impact 3rd

Dual protagonists, one man and one woman. The female lead isn't set yet, so feel free to make suggestions. Kamen Rider, Honkai Impact 3rd, secret identities (if there's one you like, you can tell me. I'll add it based on the story). There may be typos, so use your imagination to fill in the gaps.

The author is a student and doesn't have much time, so updates will be very slow. You can save this for later. I'll update when I have time. I don't have much time, and this is an old backlog of chapters. Don't read if you mind elementary-school-level writing.
