Kurai-san (くらいさん, Kurai-san). Her name comes from kurai (暗い, kurai) meaning dark or gloomy. She always has a notebook with her, in which she records her observations along with the time. She is a second graduate of Megaku.
There was a SNT (Saturday Night Tissue Maid) thread on Saturday nights (sometimes on Sunday nights since the initials are the same).
She used to write the contents of her diary in a stand-alone thread, but one day she lost it and saddened many users including Nemui-san. After that, she sometimes wanders back to img and makes a new thread.
She keeps her black hair tied back in braids, wears glasses and a lemonhead hairclip, off-setting her black maid outfit. she sometimes dresses in gothic lolita style outfit.
She has a very gloomy outlook on life. She hates birds due to childhood trauma of the movie The Birds but loves dogs, including Wanku. Her combat power against birds is so high that she can capture Yabai-san, although she gets nosebleeds.
Because of the strong image of her diary, people tend to think that she is quiet, but they are surprised when she sometimes talks.
She and her sister, Iraku-san, do not get along well and fight hard.
