The best thing about this manga is the ejoyment and the story (mistery, romance, drama), you never get bored reading it, and the story make you want to know even more details about some facts that happened.
There are the MCs that are like soldier, they fight in a Tower that is said is evil and if not destroyed can put all the Japan in danger.
That tower in reality has a lot of secrets! Is not what the MCs think it is and all the things they ve done, like killing, are not really justified.
I think someone from behind is manupulating everything and leing about the tower real function.
The Art in good, nothing special and also the characters, that's dont mean that they arent good, just they're not suited for an interessant story like this one is.
If art and character were better this manga would be an outstanding one!
I've noticed that there's only 16 chapters and not 26, i think this manga is ongoing and is not completly aired yet and! It's a shame since I want absolutly read all the manga because I was in a interessant part of it.
For the moment is a 8 overall, but could be 9 if I can finish it and if the end is good.
