The manga start off pretty strong with a decent plot. A naive hero moving from country to the capital with desire to save this village; then he get involve with an assassin group who's doing typical shounen things. The art style is good; the gore and twisted scenes was pretty nice (though they're a bit unsuitable for a Shounen manga). The first 15 chapter start out pretty nice pace with the hero get to know each member of the organization, each of them has different past but overall, they're either rejected by the society or just outlaw. The point is, there's no link between their past with their current behavior (For example: you are treated poorly in the past, you grow up wanting to kill all the evil 😕 ).
The author try to make an unpredictable plot; however, it serve no real purpose
as the author killed of some characters unnecessarily; however, there's not enough character development for the readers to feel emotional attach to the death
The main character is just typical Shounen male: heroic, one dimensional, a little emo, cry very often. However this is a Shounen manga, so I would expect just as much.
The story get succumb into typical crappy Shounen plot (because there are many good Shounen plot, this one is not) very quickly: heroes constantly spitting nonsense about good and evil as if the world is only black and white. The moral of the story is broken even though the author try to make the villain as evil as he/she can. The heroes and villains are one dimensional at best. Some characteristic was introduce: glutton, sadist etc, and most of them are shown in a skew manner and unrealistic.
Humor are put in different parts inappropriately, during fight, or between villain and hero. Typical shounen humor including: cooking, romance, hot spring, blush, shopping etc.
Romance is introduced very forcefully like most cliche Harem Shounen i.e. girl blush and fall in love with boy after a few sentences; and the other males are just fodder with no real purpose. The story turns worst after the sadist general (suppose to be villain) suddenly fall in love with the hero in the most nonsense way possible (she need to know how to feel in love... give me a break).
The teigu is a pretty interesting power system as each of them has different characteristic, function and rules; however, there's nothing special about them (Example: water control teigu, 1 hit kill katana teigu etc.)
Villain are introduced one after another, and heroes cut them down one by one; it gets boring quick.
Overall, 4/10 very disappointed to a highly potential manga.
