Chi (千)'s Links
It was very jarring for Chi to have someone pop out of nowhere and claim they know her past. That fact was what made Chi cautious and unsure to be around Kei.
She sometimes finds it nice to have someone to talk to about it, although she wont admit it.
Kei sees Chi as a familiar face moving into a new city alone. Determined to enjoy his time, he finds himself naturally bothering Chi since them being from the same hometown gives him a (one-sided) sense of solidarity with her.
He later finds Chi to cause mischief among humans which causes him to keep a close eye on her.
