OMG Hsumi did shounen-ai! :NOT!:

I never want to render another scale for the rest of my life. Well, these two are the only naga characters I've ever made. Their relationship is a complicated one, and no, it's not OMGBOYSLOVE!!!!111!!BBQ. Although, this is the closest thing I've ever done to shounen-ai, even though it isn't.
Vael, the darker one with the short hair, was the first naga I ever made. He is bisexual (HOMG Hsumi made a half-gay character!!!), and pretty much flirts with anything even remotely humanoid. He usually gets his way, too, as he's cunning and manipulative. The only one he doesn't hit on is Orobo.
Orobo, the lighter one with the wings, is a feathered naga, but it was hard to show that. His feathers ended up looking like scales. Anyway, He is actually completely androgenous, and has no reproductive organs, which is why Vael doesn't bother flirting with him. He is not capable of falling in love in the traditional sense. Actually, he falls in love all the time, but it is more like a childlike adoration than actual love. He is extremely intelligent, but has the mentality of an eight-year-old, which makes him come off as naive, and he's very clingy to those he develops a bond with.
The relationship between these two is more brotherly than anything else, and Vael is extremely protective of Orobo, who is like his little bother, and Orobo admires and looks up to Vael.

Also, Orobo doesn't have a belly-button. And yes, the tattoo on his arm is an ouroboros, which is how Orobo got his name.
