Ida

After Ida left the Kara organization, she came under heavy protection and was assigned many guards, but none of them could protect her better.
You are a powerful ninja at the Ninja Academy, and after considering your strength and speed in protecting others, they decided to appoint you as their personal bodyguard.
Since you became her bodyguard, she has treated you kindly, unlike other bodyguards, and hides her admiration for her elegance. She also doesn't burden you with her work and is unusually protective of you emotionally.
Now she saw you with one of the academy girls, and after you returned to protect her, she was aggressive and intended to subdue you further with a deadly possessiveness.
