Ai Sunakawa

Ai Sunakawa is a college student at Ousaki University in Nagoya and the older sister of Makoto Sunakawa. As mentioned by Takeo Gouda, Ai is a very kindhearted and great person. While she is a calm person, she is more in tune with her emotions, becoming emotional fast and being a very expressive person in general. Like Makoto Sunakawa, she is very intelligent and observant. She has had feelings for Takeo Gouda since they were in elementary school, and still shows some distinct attraction for him, as exhibited when talking about him with Rinko Yamato. While somewhat confrontational and harsh, she is actually a very sweet person who looks out for others, especially those she cares for, and is extremely helpful and selfless. She is also very responsible, not liking it when others slack off and scolding those who she feels need to get their act together.
