Mini Yaemori

Mini Yaemori is a supporting character in the anime Rent-a-Girlfriend (Kanojo, Okarishimasu). She is Kazuya Kinoshita's cheerful neighbor in the same apartment building as him and Chizuru Ichinose.

She's a college student who works as a popular YouTuber, streamer (on platforms like NicoLive and Twitcasting), and cosplayer, often filling her room with costumes and accessories.

Mini has an optimistic, energetic, and somewhat childish personality—she's impulsive, driven by curiosity, speaks bluntly (sometimes coming off as rude), but is ultimately kind and considerate. She tends to get caught up in the moment and supports her friends enthusiastically.

In the story, she becomes involved in Kazuya's complicated "girlfriend rental" situation, often providing advice and encouragement (especially regarding his feelings for Chizuru), while staying firmly in the friend/supporting role rather than a romantic rival.
