Unicorns have the basic appearance of a horse, but with a horn growing out from it's head.

When Issei first met him, it was serving as the tennis team's headless mascot under the name "No Head Honda". Normally Honda wouldn't be allowed near the tennis team, but Rias and Sona were okay with it since he was doing it as a mascot.
