She frequently goes on missions with her closest fellow Japanese agents, Sana and Momo, forming a skilled and lethal trio the agency has ever seen.

A clumsy but gets-things-done agent that works alongside her fellow Japanese agents, Sana and Mina. She plays things safe majority of a time, but life always decides to turn the tables on her, resulting in humorous or ridiculous situations she finds herself in.
