Tanaka serves as Fuzuki's maid. She can be quite silly at times, but she has a deep affection for both Fuzuki and Mitsuki. Tanaka excels in various household tasks such as cooking, cleaning, and shopping, and she takes great pride in her abilities as a maid. Additionally, she tends to be nosy and often eavesdrops on conversations.
In the anime, Tanaka is depicted as a music lover who listens to her radio with headphones so that Fuzuki remains unaware. Mitsuki occasionally uses this secret to blackmail Tanaka. Tanaka also harbors a crush on Wakaoji and feels jealous of Oshige, mistakenly thinking she is Wakaoji's fiancée. In one episode, Tanaka challenges Oshige to a contest to determine who would make a better bride. Despite winning all the events, Tanaka concedes when she sees Wakaoji and Oshige laughing together, believing they are in love.
