Mmm... first, I should probably mention my first encounter with the company that made this VN, Hulotte, Imouto no Okage de Motesugite Yabai!  Moteyaba was a pretty straightforward take on the 'popular protagonist that forms a harem he eventually chooses a girlfriend from' trope, and as a result, while it was decent, I didn't find anything to be particularly interesting about it. 

In a way the same can be said about Yomeyaba, in that it uses the same (common to about ninety percent of charage) tropes and is true to the ideas behind them... but in the same breath, I can say that it did manage to distinguish itself in some ways that were different from the genre norms (well, really they just hit another cliche of a less common variant, but meh).  Basically, the protagonist in this VN is the descendant of a kami (I distinguish 'kami' from our Western concept of God because it is distinct) and as a result, he possesses superpowers... in his case, the ability to enhance his body... and dream about his potential future wives. 

Generally speaking, this VN moves pretty fast, the common route lasting just long enough to get you to like the characters without becoming the centerpiece of the story (as is common in many charage common routes).  Instead, the centerpiece of this VN is the way the protagonist and the heroines adapt to some of the weird ways his powers and heritage effect their relationships.  As a focus, this is pretty much the ideal for a fantasy charage, as an introduced setting almost has to be utilized properly in order to make it complete (and to prevent jaded VN-gamers from bashing it up one side and down the other), lol. 

I was particularly impressed with the heroine epilogues, as they tended to be pretty good in length and extended farther along than is the norm for a charage (normally, it ends before they graduate from school).  This allows you to have a good idea of what the characters' lives are like after marriage (which is one of the major focuses of the VN) and gives you a sense of closure many charage are deliberately designed not to give you (so they have an excuse to wring more money out of fanboys with fandiscs). 

There is a harem route in this VN... and oddly, it is one of the few harem routes I've encountered that were foreshadowed or made sense in the greater context of the story, in my experience (some story-focused VNs also have harem endings that are the results of really unusual situations, and this is close to those, albeit with more sex).  It explains some of the divine relations between Yoshihara Ookami (the kami from which the protagonist and his family are descended) and his wives, giving you a general idea of how it relates to Daiki and his wives in the harem route. 

Overall, this VN was interesting... and people who like charage with ichaicha and decent drama will find this to be well within their allowable limits... but the fantasy element probably won't satisfy someone who likes superpowered combat and the like, as there is none of that.  The protagonist rarely uses his powers, though the heroines with powers do so a lot more profligately, lol.
