Okay I can be first here I don't mind that. Okay it is says it is 10 vol. yes it is but unable to read for free, i found book to 3 vol. but lol in italian but at least I could get what is going about from the art story which is pretty cool. Also this is they means Rei and Mahiro are not not siblings at all, and it doesn't matter if their parents get together, this is totally misunderstanding. It would be totally different if they would have same mum or dad, but it sound it wasn't that way. So this is normaleven in real life.
Art is is pretty amazing, really everything get good details on.
Just that thing I am not able to read for free to the end and I can't say it that I like it or not, but the beginning it was in great action and keeps wanting to read more and more, and it is nothing really mean that I dropped it you may think I don't like it, this is not true. If i will find out more vol. to read I will edit as I reading more, but right now I am keep busy with own writing stories. xx thanks
