Section 2 Division 2 Team 1: The bubbly, perky, red-headed labor otaku from Hokkaid�. The main character of the show, Noa is usually the one at the center of the action. Noa loves her labor much like a pet and named it "Alphonse", a name previously held by a pet dog and a pet cat she had while growing up. She's impulsive and doesn't think things through, but not nearly as much as Ohta. Noa is arguably the best pilot in Division 2, although both Clancy and Kumagami have shown extreme talent as well but rarely pilot. She has a natural affinity for labors and gets 110% out of it, much to her partner's amazement. She can drink quite a bit more than her coworkers, and recovers from hangovers much faster since her family runs a liquor store. (Source: Wikipedia)

Later she decides to live in Nagasumi's house until his servant status is over. (Source: Wikipedia)

He also has agoraphobia, which is why he travels only in submarines and wears an astronaut's suit in open spaces. While looking for a servant he befriends Saru. His name is related to Mikawa Bay and Neptune (海王星, kai�sei?). (wikipedia)
