29 June 2012: The End of Tasogare Otome x Amnesia ~Air/My Purest Love for Hime Cuts~
I can't think of a way to address the end of Tasogare Otome x Amnesia without revealing fairly important spoilers, but I'll try to minimize the damage. Anyone paying attention likely already knows the ending suffers from a serious flaw, though.
As you might expect, the anime's ending stumbled because the original manga is still ongoing. This gave the Tasogare Otome x Amnesia anime basically three choices: (1) A non-ending ending, which seems to be the most common cop-out, (2) an original ending after diverging from the manga (Full Moon wo Sagashite did this with amazing success), or (3) a real ending that the original (but still ongoing) manga later attempts to follow or improve upon, as in the case of the Neon Genesis Evangelion manga.
Well, the Tasogare Otome x Amnesia anime took the first choice...sort of, but did it in a way that is both better and worse than the typical non-ending ending: It has an original, option-two-type ending which is actually pretty good, but then at the last minute it turns into a non-ending ending, betraying any emotional investment or payoff it might have achieved had it just wrapped things up there. I'm not sure if Silver Link simply chickened out, or if they have hopes for a second season.
I just said the almost ending is "actually pretty good," but it has a few problems too. Yuuko and Teiichi obviously won't get a happy ending together; Yuuko is dead, after all. But no matter how successful Tasogare Otome x Amnesia may have portrayed the romance, it's still difficult to forget that Teiichi is only a first-year middle school kid. He's just not old enough to be making such bold pronouncements about love and still be taken seriously. This is one place where a timeskip would have been appropriate before the bittersweet ending it tried to achieve. Either way, the anime should have left it alone instead of forcing an opening for a possible sequel. It's a stunning lack of commitment to a conclusion that invoked commitment as a major theme.
