Tasogare Otome x Amnesia
MY BROTHER. The only other series I've read to date that has a shot at surpassing it is Screaming Lessons (which I can't recommend with anywhere near the same conviction as Tasogare, since it's, uh, more of an acquired taste).
I should clarify that I did think Yuuko was an excellent character! If she hadn't been as radiant and likable as she was then the story wouldn't have affected me as much as it did. By "truly exceptional" I was talking something like top 10 status, and while I'm happy to sing Yuuko's praises, I wouldn't quite put her on that high a pedestal.
The art was what initially stood out to me when I first picked this up, though now I appreciate that it's just one part of an overall amazing package. One of the reasons I'm less enthusiastic about Kekkon Yubiwa Monogatari is because it's evidently not the same kind of story, and I'll miss the deliberate art techniques used to create Tasogare's frequently ominous atmosphere
I ordered the anime from the US a few days ago in anticipation of finishing this, because it's my only real alternative without the manga being published in English. Will probably wait a while before watching it, because I'd rather let the story fade from my mind a bit so that it feels slightly fresher.
The thanking is mutual, since
you partially inspired me to finish it off. Well, that and I was scared shitless about stumbling across an ending spoiler here, particularly when you and Save 'N Quit were discussing it.
