So in case you're wondering, this is a Netflix series. One of the bunch that they have been spitting out since the beginning of 2018. I would honestly give this anime more of a 7.5 rather than a 7 but I don't want to give it an 8. Any "spoilers" I mention are either in the synopsis or you find out in the first episode. So there are demon swords (so...refreshing) and when a human combines with them they either turn into a demon or control it and use its power...sorta. The twist is that if you use the power too much then it willconsume you anyway. So it follows this kid who ends up getting one for an arm and the story sorta is....eh. The plot meanders because I think they were trying to build up all the characters to the same level of development, which for only 12 episodes is somewhat ambitious. I have to admit there were two instances where I actually felt something for the characters. The mc is supposed to be edgy, but he drifts more to just being a dick, which I can somewhat appreciate because at least he's not the "hooray I have a new power, let's save the world from evil!". I think Netflix really wants to use cg in all their anime for some reason because it's in this, sparingly thank goodness, but it takes away from rather nice visuals. The most interesting part of this anime was the concept of the "power". Besides that it was just ok. I don't remember any song that stood out. It was an easy 12 episodes to burn through. If you've got some free time I'd recommend it. the anime at the very least is enjoyable to watch.
