I loved the manga I just had to buy the full set.

The manga had a good plotline happening. It's different from your typical action thriller mangas where this story is connected to past lives while also trying to move forward in their current life. I loved the characters, almost all the characters introduced have their own backstory while some are still left in mystery. I loved the relationships these characters have with each other and that they are paired together. I don't even care that there are male-male relationships. It's not yaoi but more like shounen-ai. You just squeal at every little interaction. You can see how much the characters love each other and how far they would go for each other so a strong friendship bond can be mistaken as love.

I am disappointed that the manga ended earlier than it should be. I felt like the manga could have continued for like 5 more volumes. But it can't be helped when all this much work for such a great manga takes a lot of toil for the author. She did take a long hiatus and managed to make a comeback to finish this manga the best she can instead of just leaving it incomplete indefinitely.

In saying that, I kind of felt disappointed how some characters arc never got developed because it only got interesting just as the manga ended. While some characters did have an interesting and unexpected development, it just never had the chance to be explored but the abrupt ending. Again, I'm not going to blame the poor author who had to battle her illness while trying to finish this manga so she could focus on getting better.

The ending was left ambiguous with more questions than answers. A cliffhanger really. I was really looking forward to learning more about Luka's back story with his former master and I actually thought the guy was going to make an appearance. This is only possible if the author had the capability to continue further than the ending we got.

I'm more sad than disappointed about the ending but I also respect the author's decision to bring it to an end. She's been very ill for a long time and tried to battle it while working on the manga at the same time but it just got worse for her. She went on a really long hiatus and probably thought she can't do this to her readers any longer and thought it was best to bring it to an end - maybe not the best ending we all hope for - but it's better than leaving it incomplete forever.
Overall, I give this manga a 9 out of 10 because I did enjoy it. I loved the story. I loved the art and I loved the characters. I gave it an extra point for her efforts to complete during a difficult time. It's not a 10 out of 10 because of the ending.

I do recommend this if you don't mind an ambiguous ending. It's ambiguous but it's not a bad ending.
