The tricolor shiba becomes the main rival of the white shiba in vying for Haru's attention. She was close friends with him when they were younger and is very in love with him, and is referred to as a tsundere in the story. She is also not a fan of the girl always being by his side.

I picture a little bit tougher sounding girls voice but not too tough. Her and the white shiba are both in love with Haru but are very different types of tsundere's so I would like their voices to be contrasting a bit as well. The white shiba's is going to be a more gentle and sweet sounding voice, so I'd like a bit stronger voice for the tri's, since she's much more aggressive in her pursuit.
