As Vague as it is, there definitely is a plot behind this. But instead of having an overlapping "We need to get to X to kill Y" kinda of plot, it's mostly character-driven. Bellri, the soul-less jester that he is, has varying morality, and wavers on the sides. This happened originally because he helped an enemy soldiers whos' captain he had murdered. Being on the Amerian side, he decided to stick around to get intel on it, (like when he took photos of the amerian space army in the G-self). This could prove important to him, unfortunately that's also where his loyalty wavers, since he unknowingly kills his own teacher in combat.
Rarayia Monday has some sort of connection to the G-self, it'll probably all be explained later, bottomline is, she's probably important(?)
For the sake of the Capital Tower, there's an obvious conflcit between the Army and the Guard. The two sides have each their own methods, and you can feel the coup d'etat brewing.
Reco is suuuper scattered, yeah. It befits the attention of my bigger brother when were younger, and I can manage to drop my scholar's hat off and sit down for abit of messy fun. In the end, sure, it could be a Little Prince masterpiece where you can reread it every 10 years and get a whole new understanding, or some sort of new thriller movie with a hollywood plot ripped straight off of Sigmund Freud with Christian Bale as the cop. But, it's.. Fun. The characters are easy to understand, you can belay your time with jumping into it and grasping the concept without having to watch 13 episodes running up to it.
