"Ruby Rose and Geki Goodwitch"

The world of Remnant is a world filled with the dangers of Grimm and the White Fang, but there is a third danger...the Bugster Virus. To save the world from these dangers a video game master, a surgical prodigy, a mechanical genius, and a faunus with an attitude must learn to work together with each other and their friends.

I don't own RWBY or Kamen Rider Ex-Aid
