マリン

A young man from the Dragon Village. He tends to overthink things and ends up panicking. Because of his panic attacks, he still hasn't cleared his village's ceremony to become a complete Dragon User and is bullied by the other Dragon Users from the village. He's all about precaution and always packs way much more than he needs and spend ways more time than necessary verifying if a monster isn't just feigning death, etc...

Despite his looks, he is already a grown man. He's a hard-worker and is very smart.

When he sees Tsuuya for the first time he feels something special and when Tsuuya saves him from the village's bullies, het gets determined to pass the ceremony and become Tsuuya's partner
