Seminar[]
Hayase Yuuka[]
A fellow member of Seminar who works as Millennium's treasurer. Since Yuuka is always overworking herself, Noa tends to help her out whenever she can. She is aware of Yuuka's romantic feelings towards Sensei and teases her over it, enjoying the flustered reactions that result. The two have been close friends for some time and little seems to threaten it.
Tsukatsuki Rio[]
The lone wolf known as Seminar's president. Since Rio prefers working alone, Noa doesn't see her often, but she knows for a fact that Rio is always up to no good, whatever it is she's planning.
Kurosaki Koyuki[]
In Volume F, Koyuki seems to fear Noa yet is somehow not scared by the titled "Cruel Arithmetician" that is Yuuka.
Veritas[]
Kagami Chihiro[]
Due to some history between Veritas' president and Seminar's president, Veritas and Seminar don't exactly get along together. Despite that, Noa asked for Chihiro's help alongside the other Veritas members to help with computational work in the On Your Mark @ Millennium Event.
Engineering Department[]
Shiraishi Utaha[]
During the On Your Mark ＠ Millennium event, Noa requested Utaha's help in restoring a broken cheerbot for the event. Utaha instead insisted that she and her other club members make a new one.
Game Development Department[]
Tendou Alice[]
In V2C2, Noa played a big part in rescuing Alice from Eridu by initiating a last-second electrical blackout, preventing <Key> from beginning construction of the Ark of Atra-Hasis.
Gym Training Department[]
Otohana Sumire[]
In the On Your Mark @ Millennium Event, Noa requested Sumire to train Millennium's athletes who will be participating in the Halo Games.
