Already over! Giveaway for Touhou fans

I know and that's a shame. The questions are about Touhou and the prize is something a Touhou fan would like though.

you don't need to

nothing working here too

Make your first puzzle and the whole website crashes. Just my luck D:
Edit: it's back up now

I suggest you to use the Wikia instead of the Wiki and remember to check the "Fun Facts" and "Fan Culture" tabs for 5 and 11. Hints appear after 10 minutes of waiting, they might be of some use.
10 might be a bit too hard for people who don't know much about Touhou so I'm giving one extra hint: You can find the answer from Touhou 12 & 13.

I noticed some of this girls have over 500 or over 1000 years, and really considered young have less than 100

A yes 11 was very easy, I remembered what she did in one fan anime serie, and answer was correct, so now only 5 :S

EDIT: I found 5th too, I was writing it incorrectly with F at begin
