Is that tania with blond hair and blue eyes? Arquero (seiyuu: Ishikawa Yui)

Su Fang's classmate and good friend, a gentle and kind blonde girl. I admire my senior Carney and secretly envy her close relationship with Su Fang. When I first started dating Carney, I became a contractor. My ability is to manipulate a large number of bugs (cockroaches in animation) at the expense of broken hair. Personality also becomes indifferent and forgets feelings. After being incorporated by FSB, he participated in the pursuit of Su Fang and was finally killed by Zi Yuan.

The blond man is Carney. If I remember correctly, he should have been killed by tania. . .

The other is Su Fang's classmate, but he plays soy sauce. . .
