Q　 TSF（性転換もの）ですか？
A　 はい。エロが主体ではなく放送禁止には当たらないと考えていますが、そのご判断は見る側に委ねさせてください。

Q　 Can i ask what is the password with this one?

A　 Thanks for playing!
Clues to the problem can be found in the diary in Raito(来人)'s room and on posters in the hallways here and there.
But, if you cannot read Japanese names, you will not be able to solve that problem.

寅太(Torata):Jacob's syndrome:XYY.
来人(Raito):Klinefelter syndrome:XXY.
夕菜(Yuuna):Turner Syndrome:X
TRY:XYYXXYX

Good luck!
