And here's Kokoro's more mellow brother, Aoi.
It took a while to figure out his colours. I knew I wanted a blue scheme (since his name literally means "blue") but I didn't know what shades of blue and where everything was going to be.

Aoi the Tiger Shark
- Name: Aoi Hitsugaya

- Age: 15
- Gender: Male
- Species: Tiger shark
- Height: 3'2"
- Weight: 67 lbs.

- Personality: Aoi has a tendency to act like a tough guy, but in reality, he is very kind-hearted and easily intimidated. He often tries to take charge until he realizes how hard being a leader really is, and then passes the role off to someone else (usually his sister). He seems to have a soft spot for small children.
