Trans Star

It zips through the story at a fairly breakneck pace, but being a one-shot, this can't really be helped. Likewise, there's only the barest of characterization (though still a surprisingly decent amount, considering the length). The TS disease is basically just wibbly-wobbly biobabble that's incredibly unrealistic and is transparently just to excuse the circumstances of the plot, but given the "moral" of the story, and how we're basically only introduced to the character post-disease, I'm also willing to excuse this as it pretty much just seems to be a story meant to attempt to bring some light and acceptance to homosexuality in Japan. If you'rewilling to excuse these flaws, and a few other minor niggles, it's an adorable, heart-warming story whose only serious flaw is not having been given a serialized run.
