Her parents are working abroad and hence do not appear in the anime. Chiaki is kind, honest and has a good heart. She believes in people and wants to protect them. Chiaki has three dear friends at school (Sayaka, Ako, and Ayame). She gets along very well with Akira/Goki (from season 2 onwards) but often quarrels with Zenki as though he were her little brother, mostly because he is disobedient and shows no respect to other people. The bond between the trio becomes powerful and indestructible in later chapters when they face the evil together.
