At first, Chu Cai lived an ordinary life like other magicians and had a friend. However, in Mako Fujisaki's attack, her so-called best friend ran away without fear, which also made Chu Mei feel disappointed with human beings. However, she also learned about the Observatory and other magicians from Mako Sakurai and decided to look for them.
The first dish that came to the observatory was a mess, but Mei soon woke up and explained the reason to her. At the beginning of the dish, I knew about Chennai and Mei, but I didn't know about the eagle bird. Later, when everyone was washing hot springs, Chu realized Murakami's help to everyone and decided to give it a try. In the process of bathing in the village, she deliberately asked him for help and then fell from the sky. Murakami jumped down to save her, grabbed her hand, and they hung in mid-air.
At this time, Chucai knew Murakami's mind and told him his ability, but Murakami mistakenly thought Chucai was deceiving himself because of the black cat, and refused to let go anyway. After Murakami saved her, Murakami fell from the tower, but fortunately, the bird and others arrived and saved their lives with their own abilities.
Chu Cai fell in love with him in a series of actions in Murakami, gave him a kiss and fled the scene, leaving everyone in a mess. Although Chucai has believed in Murakami, she still can't help but want to test the feelings between other witches. She lied to herself that there were only ten days of medicine, but there were still 24 days left.
After that, Chu Cai participated in their lucky draw to distribute sedatives, which once again confirmed their profound friendship. Later, the first dish I didn't know told Murakami that Kuroha was a black cat.
And in the evening, nine thousand pity found the observatory through Mako's information and wanted to kill everyone. Although the first set was knocked down by Mako, she couldn't eject her because she couldn't understand the magic bender behind her, and Mako cut her into two parts. Then the bird was taken away and Murakami died to protect Zi Ning. Chu Cai decided to add his own ability to Murakami and sacrifice himself to revive Murakami.
Murakami was successfully resurrected, and Chu Cai was surprised to find that although he was dissolved, he did not die. Since then, Cai Cai has participated in the plan to save birds with Murakami and others. The rescue plan was carried out by Zi Ning, Hemei and Chucai, while Murakami was stunned by Zi Ning and stayed at the Observatory. Chu Cai and others who sneaked into the base met Zhen Zi, then they were stunned, Mei was beheaded, and Chu Cai was blown to powder.
However, Chu Cai's regenerative ability is stronger than expected. She not only revived, but also revived the dead beauty around her. After that, although her body dissolved and hung, Mei wrapped her in a cloth and fled the institute.
