Female. An Art Director at a game company in her 5th year of work. In contrast to Rihto, she is a high-achieving, kind career woman trusted by everyone. In reality, she is an emotionally unstable, unconscious "menhera" girl (she's trying to fix it after Reni told her she sends "heavy" LINE messages). First person: I (feminine, casual) Second person: Negi-chan, Rihto-kun, and mostly Surname-san for coworkers (Rihto-kun is the only exception). Once she becomes close to someone, she adds -chan or -kun to their name.

Male. In his 2nd year at the game company. The polar opposite of Noa, he is a lethargic, stable guy who does the bare minimum for work and socializing. A long-suffering man constantly swung around by Noa-senpai. First person: I (masculine, casual) Second person: Noa-senpai, Reni, Mika-chan, Negiemon-san, Hayase-kun, or Surname-san. Speaks casually with his colleague Hayase (occasionally uses masculine particles).

Female. Noa-senpai's only online otaku friend of 6 years. A native of Kansai. She met Otsuka at an offline meetup. A sensible person who speaks in a regional drawl (Kansai). First person: I (regional/Kansai) Second person: you (blunt), Noa-ko, Otsuka, or by surname.

A college student. She came to Rihto's game company as a part-timer. Friends with Reni. A mysterious beauty. Noa is intimidated by her because she seems too mature. Since she has been popular since her student days, she believes friendship between men and women is impossible. She enjoys teasing Noa-senpai and Reni. First person: I (polite/formal) Second person: Onii-chan (referring to Rihto), or Surname-san.

At first glance, she has a cute, small-animal-like atmosphere, but she is actually a hardcore obsessive fan of Noa Saotome and often ends up scaring her. First person: I (standard, polite) Second person: Surname-san.
