Here's my review for Senran Kagura Shinovi Master, I wrote this review to help you understand more about the story and how to understand it a little bit without much spoilers. Story 8/10 : If you watched Senran Kagura I recommend you to play the games of the series, actually the games tells many things about the story that it doesn't shows in the anime. I first of all recommend you to play "Senran Kagura Shinovi Versus" to understand more of the story, so as I played the game I know the introduction of the characters and etc, the game actually tells lots things about thestory that the anime... eeh don't have much time to tell in just 12 episodes, the story is not the best but still pretty good.

Art 9/10 : Yes, the animation is really good, I noticed some "mistakes" of the animations in some episodes, but overall I liked, they focused in the fan-service and that's most because senran kagura is also about it, since I watched the first season and the game is something like all about it to be honest, so concidering it in first place, there's nothing wrong since it is a ECCHI anime.

Sound 6/10 : Honestly liked the job of the voice actors, they're pretty good, Hara-San did a great job with Yumi's voice, as the others voice actors did with the others characters as well, but there's lots of mistakes I noticed over the episodes that was like some voices a bit delayed, as the "sound effects" as well.

Character 10/10 : Well I love the Senran Kagura characters, and as I told in the story review, the character yes have its introduction but in the game, so let's just not counting the introductions actually, since I know all because of the game. My favorite characters are Murakumo, Yumi and Ryouna, some characters yes just force a little bit because of the story (example: Asuka could just tell some of her friends what was happening, because... THEY'RE FRIENDS, or best friends whatever) but I still liked all them, they're funny, and not like in some comedy animes which the characters are totally not funny even the anime being a COMEDY anime.

Enjoyment 7/10 : Eh I'm honestly just watching it because I actually liked the first season, not really much but still liked it, liked a lot the games, they're fun to play and tells a lot about the story, now about this season, I enjoyed it yes, the characters are funny, mainly Ryouna, in the game she's really funny as well, both to play with and her behaviors, and in the anime she just kept it, I really liked that point, and as a ecchi anime it's not bad, as it says its really a good ecchi anime, but what I recommend to know the story before just watch it or whatever because of the fan-service and just write a bad review of the anime by just watching 4 episodes. :P

Overall 8/10 : I'm actually not enjoying so much animes lately, so 8/10 it's a great rate from me, and also finished the anime (probably if you're reading it I finished it yeh, but now when writing it I'm on episode 11), it's really good, but if you just watch the anime and not play at least Senran Kagura Shinovi Versus, you will lost some important parts of the story (the fights between the schools what was really important for the story since it tells how everyone become friends, the introduction of each character and some more).

P.S: Didn't wanted to give spoilers in the last "overall" review, but it's really important to play the game if you liked the first season and want to know more about the story.
