Akari Inuyama

She appears from Chapter 22 of the original work. She is Aoi's younger sister. She looks like a younger version of Aoi, with the same thick eyebrows and Kansai dialect. Chiaki calls her "Chibi Inuko," and they are close enough to talk and play without reservation. She loves telling tall tales, and like her sister, her eyes wander when she lies. In the TV anime, her appearance is moved up to Episode 9 of the first season, and in the TV drama, she appears from the special episode. In Chapter 41 of the original work, she consults Aoi about wanting to visit an animal park on the Izu Peninsula with capybaras soaking in hot springs, and she ends up joining Nadeshiko and the others on their Izu camping trip. In the movie, she goes on to attend an art university. Her relationship with Chiaki remains unchanged.
