Ugh... Everyone's a meganekko nowadays. I never really understood that fetish =_=

well it is nice it works for some girls I am not a complete meganekko maniac but I do like my glasses girls

For Darksheath and anyone else who doesn't understand(I know I can quote, but it doesn't appear to be working for me):

Mystia has a knife. Sakuya is a time-stopping knife-throwing badass maid. Mystia is wearing glasses. Rinnosuke is a glasses-wearing shopkeeper.
