At first Chino was generally shy with Cocoa, matching a tsundere character. She rarely complies with her wish to recognize her as a big sister figure, and has no problem being blunt with her. While she enjoys compliments from others, she tends to react meanly with Cocoa. But over time begins to care for her; to the point of even gaining a small crush on her late in the series. Surprisingly, she actually agrees with Cocoa some of the time over childish things.
Given how long she's known her, she tends to be the least surprised by Rize's behavior. She is fine with her- although she often gets frightened by her intense nature.
Chino does not interact with her much, but shares the same opinions of her that Rize or Sharo often have.
Like Cocoa, at first an image as to what Sharo was truly like had been built up in her mind. She was led to believe that Sharo is a fancy girl of wealth and only used to the finest of things. Even after learning the truth, she still deems her to be a girl of class and refinement and looks up to her. She enjoys being doted upon by her and never minds the attention.
Tippy is Chino's grandfather, trapped in a female angora rabbit's body. Chino normally carries Tippy around on top of her head during the day and is very close to him. Besides her father, she is aware of his true identity and often refers to it- which goes unnoticed by the others.
Her best friends that attend school with her and normally hang out with her. She is straight-forward and honest with them, but is genuinely kinder to them than she is with Cocoa.
For a short time Chino treated Mocha just the same as she did Cocoa. But due to her natural older sister personality she was quick to reconsider. She also enjoys the attention given to her by Mocha and got along with her well.
