Keep in mind this review is being written a few years after watching the anime and I have done no recap whatsoever.
This is gonna be pretty short and to the point. I would be putting this as a high 7 if the last several episodes were not entirely non-canon and passed off as a canon ending. Not only did it feel cheap while watching but also feels like a desperate attempt to continue. I understand it is likely due to needing to fill episode slots but I can't ignore that it also chalks up to bad planning. I do enjoy the anime a great deal for the larger part and I adore season 2 for both it's continued high quality as well as its ability to stop rather than drag it out like season 1 did. Still good non-the less as it's an interesting story. It definitely follows the formula of the protagonist having some incredible power unique to himself as well as rage being a trigger...also uses a sword. Writing it, it sounds like naruto and ichigo had a baby but aye it's still alright and although honestly some of the characters are better not being around as they drain my life to watch it's worth a watch.
The story is still interesting enough that I find it engaging and the art is quite good, especially times where Rin's eyes go full spaz from rage. Honestly most of the enjoyment I got from the show though, were from times where he basically flexed on his class. I might be watching too many biggest anime flexes by NUX TAKU...HA YOU THOUGHT WRONG!! AS THERE IS NEVER SUCH A THING AS TOO MANY FLEXES!! Anyway like I said earlier the characters are eh. Rin's cool and the dude with a mohawk was alright as well, but the larger portion of the cast was not...good. Yukio (I think that's his name) was ok I guess, I could live with him and so was the teacher with big tits and a sword (Not coz she has big tits and a sword honestly they pushed her fan service too hard). Kuro was fun and the main demons were actually entertaining. Am I missing anything? Nah I don't think so.
6/10
