Hinae is a very cheerful and bubbly person, both inside and out, a stark contrast to her daughter. She even holds this demeanor when talking about Hidomi's father or using a knife to get a simple morning greeting out of her. She's not one to hold a grudge, forgiving Jinyu overnight for hitting Hidomi with a car and hiring her to make up for it. When teaching Jinyu how to prepare meals, she puts a big emphasis on a positive customer experience and doesn't fault her for making a mess during the learning process.

Hinae's tone is usually peppy and very expressive.
