What to say? It's nothing special but it's not bad either... the main character is a delinquent that go back in time to save her classmate or it's what he wants to do since that's his purpose in this first chapter XD
Like I said, the chapter is normal: a bad thing happen, the main character wants to save her classmate, someone gives him the opportunity to go back in time and from here the story starts. Maybe the next chapters will be better... who knows? I will read the next chapters but I don't have much hype for it...
For the style of the drawings... they are ok... nothing special but I like them ^^
