She won't explode. I think sometimes they explode when they have those extreme bloat cases and their stomachs look like a bubble (see through and everything).
I don't think Seiya looks too bad, yet, but I would probably prepare for the worst with Amaterasu. If it happens anything like Okami, she will probably decline over the course of the day. I really don't think she looks that good :/
I'm sorry. I hope she's not in too much pain, and I'll keep her and Seiya in my prayers. He's such a gorgeous boy!
