traveler (?) Kamishiro Rui

Kamishiro Rui is an inventor and not a great, but a scientist.

2297 year. The year in which Rui lived. He always wanted to create something that would help humanity and bring enormous opportunities in the future. One of these projects was the “Time Machine” project and surprisingly..it really worked..A small mechanical watch but with a special feature. The time machine worked like a charm. Only...when Rui was about to go to the future, something went wrong and the clock started blinking strangely and then..

Rui found himself in an unknown year. It looked like the 18th or 19th century. One thing was clear: the watch was broken. It was unsafe to use.

anyway, it doesn't matter now, because the royal guards took him away, considering him "an evil magician from a neighboring kingdom" and brought him to the king - Tsukasa Tenma.

"No, your highness..I'm not a magician or anything. I'm... a traveler."
