- Koro (コロ?) is a creature from the spinoff Isekai no Seikishi Monogatari also known as Saint Knight's Tale and Tenchi Muyo! War on Geminar.
- They are usually used as warning guards from enemies and dangers. It has been known that Kenshi looks like one of them from the girls nearby and students from Holy Land Academy.
- They have a special affinity to Kenshi and his crystal. They tend to gather around Kenshi when he is nearby and when Ulyte performs tests on his crystal, possibly a Core Crystal, Koros swarmed together outside the room, covering all visual space outside the room's window .
