Story 1/10
Normally I would be very careful so I wouldn't include any spoilers here, but then as I recall the anime that I watched a few hours ago, it lacked something very important. An actual storyline. No plot. At least no essential plot. What they tried to tell us is that a high school transfer student, Jouji Gouda, arrives at Hakuryo High School. When he is introduced to the rest of the class, he meets Suzumiya Akane, a character that is known from Kimi Ga Nozomu Eien, and blatantly proposes to her. From that point and on he constantly tries to make Akane like him.
Well, in other circumstances, this could create a good background for a decent anime but not here. Even if you come here to look for a romantic comedy, Kimi Ga Nozomu Eien heavily affects Akane Maniax and you just can't laugh no matter how hard you try. Even so, while watching the first two episodes, I tried to focus and to connect the only common thing to these two animes, which was Akane, and learn more about her emotional problems. But the poor story doesn't even let us focus on that because of the characters and their lame attitude. An attempt to combine an idiotically funny attitude from Jouji along with Akane's depressive and angry state is marked as an ultimate failure.
As this wasn't enough, this OVA series also parodies robot shows like Mazinger Z by letting Jouji actually use one. At this point you must be looking at what I have written so far and have the most confused face ever. How does one put robots and a side story from a legendary drama anime in the same series is beyond me, even if it is only for a parody. At the point where Jouji opened a school door and inside was a robot, well this part actually killed it. Parody you say? Not acceptable from me and many others. There are other ways to parody mecha shows and that's not the right way to do it.
Animation 4/10
Maybe the animation is the only thing I can hold from this anime. It had something from KGNE and this could be seen clearly from Akane but any new characters, and especially Jouji, were more than horrible. And let's not think about the robots, mecha shows would commit suicide if they saw the design. The background animation is poorly made as well, with the only exception the scenes on the hill. There were a few scenes that offered fan service mainly with Akane dancing samba almost nude and some other ecchi parts, but overall nothing too offensive.
Sound 2/10
I won't lie, with the terrible storyline, the characters and the mediocre animation, you won't be able to take a great notice of the sound. Much to my discomfort, I had to rewatch some parts to notice the sound and it wasn't anything remarkable. I think the series would have been a little better if they just muted the sound and let the characters speak.
The Opening (beginning by Kuribayashi Minami) and the Ending (Arigato... by Mizuhashi Kaori & Muv-Luv by Kuribayashi Minami) songs were very disappointing but at least they offered a better animation than the main dish.
Characters 1/10
Just meh. Seriously, Akane is buried by the horrendous party. You will only notice the famous Tsundere-style Akane has (and even that is extremely weak) but that's it. Jouji can easily become one of the most hated characters among all animes, as both with his violent and with his childish lovey-dovey attitude totally ruins the whole thing. The rest characters are a nuisance as well. Now for the character development... Huh... Yeah there isn't any. Unless you call Akane's all-tough and tsundere attitude going towards a confessing and crying style a development, there isn't A-N-Y-T-H-I-N-G that can tie you with the characters and be considered as development.
Overall 1.5/10
What else to say... Oh like KGNE, this side story is also based on a game but not as ecchi as KGNE was. It focuses more on adventure and comedy. All these matter little though, as the anime has nothing that can give to you to remember as an extra to KGNE. And don't even think about re-watching it. Unless you are a masochist, I see no reason why anyone should torment him/herself twice. Maybe I am too good towards the anime with this rating but only for seeing Akane even a little more I feel like giving half a point more than it deserves. Recommended to no one. Honestly, if you ever planned to see this, you will be disappointed big time.
This is the first review I ever do for an anime and generally for any piece of art so please be nice.
