Anna

Anna is cheerful, sociable and enthusiastic about the share-house group's constant parties. Like her friends, she has become remarkably accustomed to Beika's extreme crime rate and refuses to let the possibility of danger prevent her from enjoying everyday life.

This attitude contrasts with Makoto Hanzawa, who arrives in Beika expecting its dangers but is unprepared for how casually its residents respond to them. Anna's behavior contributes to the sense that Beika's absurd level of crime has simply become normal for the people living there.

Anna is an ordinary civilian with no established supernatural abilities, detective training or martial-arts expertise. The spin-off uses her primarily in everyday and comedic situations rather than confrontations.

Her activities center on the social life of the share house. She participates in the group's parties and other outings, functioning as part of the community Hanzawa enters after moving to Beika.

Anna appears among the residents of the share house where Makoto Hanzawa finds accommodation. She and the other residents quickly introduce their new housemate to their habit of organizing frequent parties.

She continues appearing as part of the recurring ensemble while Hanzawa searches for employment and becomes entangled with familiar people and places from Detective Conan. Her role is deliberately small, with the group generally functioning collectively rather than receiving individual story arcs.

Makoto Hanzawa is Anna's housemate. She includes him in the group's social activities despite Makoto Hanzawa's more anxious personality and frequent concerns about spending money.

Kenji, Nana, Rika, Rikio, Yuika and Shouta belong to the same circle of share-house residents and partygoers.
