The one thing I am sure is that the girl(s) who gets him will definitely have to go through his sister, as to their relationship it is kind of ambiguous. As to the rest of the girls wouldn't be suprised if they series end with no resolution, since picking one usually signals the end of the series.
these kinds of anime dont have an ending, they just leave off on an ambiguous note with no particular member of the harem winning. however if one does(although extremely unlikely) yes, it better damn well be charlotte.
This aspect of the series will end in one of these three ways
1. The ever popular no ending etc they will never name a girl why you ask? simply the Japanese get mad death threats have been sent to authors about these things. Fans GET PISSED if they pick one girl over the rest so to avoid this they leave it unsaid an "You pick" kind of deal. That's how the Japanese like it and anime and manga's main market is asia this care not for europe or the America's so your wants and wishes matter jack to them, because they make most of their money in asia so that the market they play to.
2. It would be Houki, only because if they do pick they will go with the cliche first child hood friend first girl introduced ending. This is one reasons I dislike manga's 99 percent of the times its the childhood friend or the first girl introduced.
3. It will be Chifuyu, now this gets flak but here is the thing, in Japan and asia this isn't a big deal. In may be to the US and others but again they aren't making this WITH YOU or such in mind. In Japan the incest ending is actually liked alot, plus really from the anime and LN Chifuyu has the most ground with him. Hell he ALWAYS notices her beyond the other girls its clear he considers them secondary to the rest.
On a side note, don't trust what Wiki's say in terms of relationships, alot of time wiki are edited by people who play favortism hell I read the Houki section on Ichika and hell could I spot that favortism.
They could do a multi-episode alternative ending where each character gets their own ending with ichika. It would solve a few problems but regardless I still don't want rin with ichika, everyone has their good qualities but I just can't see rin's
Phew! Thanks for the heads up about the favoritism A Wikia contributer, I almost fell for it. Damn, now I feel like I'm just as naive as Ichika. And yeah, I agree with you on how the first way seems to be the most likely way it might end, though I have a sneaking suspicion that the author might surprise us and actually put (or probably force) Ichika into a Harem marriage. So that the boys born will be able to pilot an IS or something like that.
The houki section of the Ichika relationship page was not writen with favortism. What the person who wrote the section said is true. She has stood out among the girls as his possible favorite and romantic interest. Most people agree even if they do not like it. This is shown in both media formats. In the anime their are implied hints to this. In the light novel however the hints of this are taken up to 11 in strength with in the light novels. The signs of this in the light novel are as followed. At the end of the first major Arc Ichika gives houki a birthday present as well as almost kiss her. His dilouge indicates that he want to kiss her and orginially gets anoyned when something keeps hiting him in the head preventing him from doing so (he later relizes of course that it is Celia wepon). In the events after the the first arc Ichika notices the frequency in which houki wears the ribion he gave to her and is quite happy about it. During his birhtday party he also has a strong moment with her when they are secretly watching his freind Dan filirt with one of his fellow classmates. They also have a strong romantic moment during the photo shoot they were asked to do. They also had another romantic moment in that same novel where they both went out to dinner with one another. In vol 8 he is infact disturbed and anyoyed by the other girls diliousions of him ,but when it came to houki he got extreamly jelious of the fake ichika and was determend to get the fake Ichika away from Houki. He even expressed his suprise at how worked up he got about it and didnt fully understand why. The other also take notice that Houki was the only one who was able to tell who the real Ichika and break the diliousion herself much to the anoynce to the other girls. In terms of examples in the anime they included him giving her a birthday present, him almost kissing her, him telling her how happy he is that he got to be reunited with her during the Shinono festival. In the second season he dreams about her, they have a special moment during his birthday celbration( which was totally diffrent then in the light novel) He has a nice moment with her during the photo shoot as well as some other examples. she is also shown first at the end of the episode song to be the first girl to be in the picture with ichika and chifunee. Anyway most people agree that Houki is the faviorite even if they do not like it.
The Japanese authors also don't typically allow their fans opinions to sway them. As for possible abuse and retaliation, boohoo. So, they may get some nasty emails, so what? I've interned in Japan and I can say with certainly that the writers aren't as fickle and spineless as some US authors tend to be where they will allow fans who don't like what they do with THEIR creation to pressure them.
Hell, when fans tried to threaten Hideaki Anno via mail and wrote graffiti on the wall of his studio when he gave people the TV ending of Evangelion, he gave them the middle finger by producing EOE.
So, Mr/Ms Anonymous, I don't know where you pull that number out, but it is false and straight-up delusional to think that the fandom has some influence on what the author will write.
As for Houki, yeah, she's the most likely option since she's the one that Ichika actually seems to see in more than a platonic light as evidenced throughout the series. The rest of you that think he'll end up with anyone else need to take off your shipping goggles or projecting your preferences onto Ichika because what girl you're into isn't the one he likes. Deal with it and write a fanfic where Ichika/You get your ideal woman.
