Raidou's Links
Raidou is very protective of younger merfolk, and Arte is no exception. He tends to watch over Arte and his brother Eros when Disia isn't around or if they wander off too far from the safety of the city.
Arte looks up to Raidou due to his sheer strength and the kindness he extends to defend him and his brother frequently against any kind of threat. Though he is shy, Arte would like to grow up to be as capable as Raidou is in fending for himself and that of others' well being.
