Really good, only a thing or 2 for me to mention..
I really liked the animation; you're obviously VERY skilled at using the program. There were only 2 things that I can see as POSSIBLY needing improvement.
1. The relationship: I think that it moved a little fast. If Hikaru and what's-his-face(Can't recall his name at the moment...) had gotten to know each other better, it would have made the fighting later on have more of an impact, since it would be like, "Yeah, that guy's REALLY gonna be ticked at seeing Hikaru kidnapped. Time for him to go kick butt and take names."
2. The translation: I'm not going to criticize you for having the English be imperfect, given that I'm guessing it's not your first language, but maybe you could, for the next episode, hire on someone who DOES speak primarily English to read over the words you use, to see if there's a better way of doing it, or if you might have made a mistake at the time.
All in all, the flash was really good and the storyline has me hooked already, wondering what's going to happen with the two stars. I look forward to seeing how this series develops.
