Okay I get why this anime has such a low overall score, the reason is because many people bash these kind of shows for now reason. If it isn't about cute lolis or a dumb main male character who has a harem of 20 big boob ladies then the majority of the anime community will bash it because they are just salty. Also most people don't understand that this anime is adapted from a game!!! And it did an extremely good job adapting from that game!! So simple try playing the game before watching this you will get more enjoyment out of it promise! Also I watched this anime before playing the game because I was interested in Touken Rambu I just didn't play it yet, but then after playing the game for awhile I cam back and re-watched the whole series and enjoyed it even more!
Story 9/10
The anime did a good job adapting this story because the story in the game is a bit vague unless you get special cut scenes in the game with certain swords talking to each other. I also know that the anime didn't have much story but it also was mainly a slice of life/ comedy/ "cute show" and it did a good job.
Art 8/10
The art could have been better but for a show like this the art was pretty well done. Also I am hoping the show will look even better when season two comes out. But the shows animation fit the show well and each character design was pretty accurately portrayed.
Sound 8/10
In terms of sounds the bgms were not bad, but I love that there are character songs because each ending is done by a different character and the voice actors did awesome jobs singing.
Character 9/10
Each character felt like they had a personality, and each character was colorful and distinct. The show also focused on each character for a little bit some more than others though.
Enjoyment 10/10
I loved this show and I love touken ranbu as a series, so I got a lot of enjoyment out of this cute/comedy show with tiny bits of actions here and there.
Overall 9/10
Everything balanced out for a 9/10 for me
