Chihaya Aine will not fall into the Shura field, never!

At the age of fourteen, she completed her transformation into a true magical girl, becoming the youngest in history to be able to perform a second stage of transformation. After studying in London for two years, Chihaya Aine returned to her motherland and never thought that she would encounter a lifelong bond.
Just this bond made her sweat a little.

"I can't bear being abandoned a second time, Aine!" BY Nagasaki Suyo
"Stare!!!" Yao Lenai, with his heterochromatic eyes, showed a dangerous expression at this moment.
On one side are her teammates, and on the other side are the five masked men who are trying to poach her. Chihaya Aine never thought about this.
Why did things turn out like this?
