And I was still expecting something BIG to happen when i got the last volume of it from my local bookstore, and man, seriously a letdown.
Even if the author wanted to skip everything so that it'll reach its end, he still mustn't skip the part of how he find his parents. It was like he rushed it to an end so that he can take his own personal holiday from all the weekly release stress, and that is so not good for the fans of the series.
So no, 8/10 would be enough for this. Had it not for the ending, this series could have easily scored a 9/10 or even 10/10. Oh well,the T-virus ( Troll Virus ) has now even infected the manga industry.
