Prince Osamu is the son of Emperor Tenji, and is essientally a bastard child. He was birthed to be a heir for the Aelurus kingdom once Emperor Tenji does pass away. Along with his father and him not getting along, he is very... bratty/salty. He does not like the hand he was dealt in essiental.Caring about his mother almost too much, he's more concerned for his mothers wellbeing rather than his own. If I could classify him as a eevee-lution I would classify him as a Umbreon.

Osamu is a side character.
Mid to high pitch; clear, snotty, open to suggestion.
