I am sure
someone, somewhere will find it useful. They are an exelent material for fanfiction.
But where did you find these readings? All names can have multiple readings you know (not to meationing nultiple ways to writethe sane reading, like Oonoki/Onoki). I am not even sure if the ones posted in the first page are correct.
Anyway, my rikaichan say it is everything (possiblely) correct. Exept there is a lot more readings you didn't listed. Also, apparently, Takano's given name an be 'Sachina', 'Yukina' or 'Yuna'.
But, wait a minute. That mean that even the random classnate have full name but Kunikida and Taniguchi don't?
Also, forget these two, how about Tsuruya and Sasaki? Where the hell did you find it, by the way?
