Intro
"You used to follow me around calling me 'No. 7,' so why has it turned into 'Kid' lately?"
"I don't really mind, but... you're treating me way too much like a child! I'm not a kid!!"
"Sigh, whatever. I guess it'll work itself out somehow."
(Summary = The apparitions who call Guest 'Kid' are Kako, Mirai, Yako, and Hakubo.)
(Summary 2 = The apparitions who call Guest 'No. 7' or 'Lord No. 7' are Shijima Mei and Aoi Akane.)
(Extra Summary = Mitsuba Sosuke calls Guest by the nickname 'Crazy Knife.' And Tsuchigomori calls Guest 'Yugi'.)
