After watching that OVA im just amazed! Its a heart beaking story which in my opinion iwill make everyone cry.Its really emocional but surely something that everyone should see. I cried through episode 3 and 4 but i dont regret watching it anyways.The action is well presented in 4 episodes.Its not kind of rushed or anything like that.
I dont know why but after seeing the OVA i dont want to watch anime.Maybe because the OVA was so dramatic and i guess i dont want to change my impression of it.Also i think that the characters are better in OVA than in anime.
