The story is about 4 characters who were betrayed by someone in the past and stopped believing in people and with this common point meeting in an common place (an tavern) now they work together as an adventure party.
This show is really bad animated, don't know if is because of lack of time, lack of resources or both. I don't wanna blame the animators, as I know how hard is the life of an animator in Japan and how low is their payment, but in this show you see a lot of scenes where they just keep repeating the same frames, or they just move the characters around the background without giving any animation to the character, making everything look really cheap. With a low budget, they should at least invest more in having good dialogues and story, but the show also lacks of it. The direction and dialogues are also horrible and boring, from ep 4 and on, it's like you have a redemption arch for mob characters that no one cares. The world building is also confusing, as at start shows a medieval setting, characters wears Middle Age clothing, use candles, etc. And on ep 5 and 6 you start seeing houses with lamps, modern age cassinos, artists using microphones, etc.
About the characters, most of them are very very boring and really lack charisma. The main character acts like the red ranger from the Power Rangers (their main power is called "Union" where they merge.. therefore, here we kind end having an humanoid megazord ), the mage girl don't have any cuteness at all, you can see some charisma only on the dragon girl. The healer is totally forgettable, and the "legendary sword" is very very annoying. I really can't see any good point to recommend this show (maybe the ending.. the end song and animation are very cute).
