Shouzou Kaga? If so, what a way for him to resurface like that. Been missing in action ever since TearRingSaga, as far as I can gather.
We'll need a translation patch, I guess?
UPDATE: I PM'd VincentASM about this, since I figured he'd be the one to know. Kaga keeps a blog, and has some recent posts (8 entries in 2015) about game design, AI aggression, and screenshots/character art for something called "Vestaria Chronicles."
