Chione had never been the one who trusts any other creatures so easily as before. She is always reluctant of them and would fight against them to prove their strength to her.
When she first met Amihan, she thought that the Angel God is indeed powerful. Her aura is different from the bunch and would like to be friends with her immediately.
But Amihan is as reluctant as her. Amihan rejected her friendship but Chione is persistent and asked for a duel against Amihan. None of them won because the duel was by default.
That's when they both realized that they are much stronger together but not against each other.
The second Angel God that she met is Yanna, the Dragon Lady. Yanna is playing with her familiars at that time when Chione decided to approach her for another duel.
During those times, Chione and Amihan's friendship is at a boat wreck. It's not working and none of them have time to fix what is missing or what is destroyed.
