The story revolves around a 17 years old young man named Sagara Yoshiharu, who is sent to an alternate version of the Sengoku Era without currently providing any explanation of how he achieved such a feat.
However, not is all as it seems...
Sagara quickly realizes that the fearsome Oda Nobunaga has been replaced by a girl named Oda Nobuna in this continuity and that other historical figures such as Shibata Katsuie and Niwa Nagahide have also undergone an inexplicable shift in gender.
On top of these historical inconsistencies, he is mistreated and/or not taken seriously within the Oda clan and has to earn the trust and respect of his own companions and the fiery Nobuna and maybe find love...
Note: All following statements explaining my scores are but mere opinion. Also, I have only watched two episodes as of now so my opinion on the series may change along the way.
Story: 8/10
I think the main appeal of the story is the potential it holds when it comes to changing historical facts as current episodes show Sagara actively trying to alter the course of history as he knows it so that Nobuna doesn't become like Nobunaga and leaves one to wonder what will happen to the roles of Toyotomi Hideyoshi and Tokugawa Iyeasu if she remains alive unlike her historical counterpart or just how far will Sagara's knowledge of the future will get him before he gets a prediction wrong.
Another good aspect of the story is how the comedy aspect of the show does not overlap on the serious aspect of the story like say...Nyarko-san where there was virtually no boundary between the two.
Art: 8/10
As expected from Madhouse Studios, the art is just fine, the ecchiness is mild and not too overbearing. There isn't anything wrong with the animation in general at first glance though I did not make a thorough investigation (as in frame by frame) like I usually do.
The only complaint I would have is against the ending sequence, did they really have to put so much ecchi shots cause it's literally made of them!
Sound: 8/10
The sound and voices are fine as well, the background music and sound effects reflects the mood of the scenes and aren't squeaky or unbearable and the voices are pretty good as well.
Character: 8/10
Every character is well fleshed out and don't feel like you're talking to a random background character. Here's a short list:
Sagara: A harem hero who has 'balls', that's all you need to know.
Nobuna: The Tsundere who is quite reckless and her inability to say what she wants honestly is a flaw can make her as dangerous as Nobunaga himself if no one is there to voice their opposition.
Katsuie: The big chested girl who is serious most of the time and gets embarrassed quite easily, follows the 'knight' archetype.
Niwa: The 'ojou' type-2 (TvTropes) girl who acts cool and mature and likes to rate people and their actions.
Goemon: The loli girl who has difficulty speaking coherently as her speech drags on and is actually pretty skilled as a ninja, which may hint to having been trained so hard she didn't get a proper education.
(There are obviously more, I'm just naming the 'main' ones)
Overall: 8/10
Over all, Oda Nobuna no Yabou is a really unique 'harem'/comedy anime that has a hidden flavor for any Japanese history maniacs if on is willing to look past all the 'anime' aspect of the show and can be very enjoyable.
