This club is dedicated to Kuyoh Suoh, a character from volume 9 of the Suzumiya Haruhi series. She is the "Anti-SOS Brigade"'s counterpart to Yuki Nagato, but is a far cruder interface, and is from a faction named by the Integrated Data Sentient Entity as the Sky Canopy Domain.
And she is awesome.
The underscores in the title come from the way her speech is written in the novel. :D
