And you thought Anima was spooky. What do you get when you cross Fatal Frame with FFX? You get... Yuurei.
Originally, this stemmed from one of my innumerable online RPGs, where Mafuyu (from Fatal Frame) ended up getting tangled with Seymour and his quest for power, and in the long run becoming the fayth of the aeon 'Yuurei'. Functionally, it behaved much like Doomtrain from FF8.
Colored hastily, but... it's 11:30pm, and I didn't feel like busting my butt on the colorjob.
