Main site page thingy, with Hoyden's imouto's art and fanfics. HP, Animorphs, and some oddities that can only make her onee-san shake her head with disbelief. It's fun in a pink sort of way.
Tenshi Project
The Tenshi Project has an entire hoard of scans from the series and lots of wonderful info. Just go. Now might be good.

Check out Lev and Mel-kitsune's fics - they're yummy Raphael/Mikael yaoi fics, and thus these two are Hoyden's cup of tea. Figuratively speaking.^^
DragonFeathres
Feathre's site, with so much yummy art goodness! Also amusing random facts concerning French and microwaves. We should all be so talented.^^
