The story is banal and doesn't really require much in-depth description. The male lead, Ryosuke Kaga, is the stereotypical high school anime pervert and lives out his days oblivious to the powers high above. One day he meets a redhead death god, Restall Risara, who happens to be on a hunt for the human with the highest amount of spiritual energy, or the "special specimen" as it's called in this anime. The first episode already looks somewhat similar to Bleach, plot-wise. Those of you that watched it, you surely remember the first episode where Ichigo and Rukia meet - it's raining outside and she stabs him with her sword so that he can defeat the hollow. Same thing in this anime, minus the hollow part and it happens inside the house. From that moment on they develop a partner (professionally speaking) relationship. Again similar to how it was done with Rukia and Ichigo in bleach, where the male lead supports the female companion character as they strive towards a common goal. Of course this might be mere coincidence, stemming from the fact that there are lots of shinigami-based animes out there and through sheer probability, at least two of them will end up being similar.
There are secondary characters of course - Fukumune Iria, Okura Mina, Sellier Quele. The first one is just for pure fanservice as is the case with Sellier. They have no real depth, the story doesn't expand upon them and they're just there so that we can see more breasts on the screen. So is the case with nearly all other female characters and it makes the series more generic. The only plot significant secondary character here would be Mina, who gradually rises in importance, especially in the later episodes of the series. Out of all characters I would say she's the responsible and sensible type but one character is not enough to make up for dozens of shallow ones.
The story progresses from being carefree with romantic undertones to full-blown romantic drama by the end. Similar to Sora no Otoshimono, again whether it's intentional or a coincidence, these are only my personal observations. Risara and Ryosuke set out on an adventure which includes defeating many hollow-like looking monsters; another apparent similarity to Bleach that I personally noticed. The two main characters evolve from being mere strangers to something a lot more than that and we can see their relationship growing with each episode. The makers have done a really good job here and the tension between Risara and Ryosuke and how they come to terms with their feelings is a highlight of this anime. I for one, was excited to see the ending and how their relationship would eventually pan-out.
As for Art, it is nicely done. Characters are well drawn. The colors are crisp and the style immediately catches your eye's full attention. One thing to note however is that violence and nudity are intertwined in this anime. A lot of fighting scenes will feature the girls being completely naked - much like in Elfen Lied, but with less blood. Whether the makers have purposefully adopted that kind of style from Elfen Lied or it's just me - I don't know, but it is something worthy to notice and discretion is advised.
The voice acting is very convincing and the VAs themselves fit in nicely with this type of anime. The soundtrack as well as the opening and ending songs are catchy.
All in all, this is a decent anime. The story isn't too bad but there are a few shortcomings, the most notable is the large amount of shallow and completely pointless characters and the fact that the plot lacks uniqueness to stand out from a pile of similar anime series. However at the same time the romance component here has been executed in the best way possible and this is a good anime for all those people who like watching romance-based series. You'll also get a few laughs out of this anime, as it is filled with eyebrow-raising situations and one liners.
Therefore 'Dakara Boku wa, H ga Dekinai' gets a rating of 7 from me. It isn't bad but it isn't very good either. Watch it for fun and definitively for the romance and you will enjoy it.
