noun
sole girl in a group of geeks; queen bee of an otaku circle
Slang term for the only female member in a male-dominated otaku club or group, often treated like a princess. Can carry a slightly mocking or self-deprecating tone.
あのサークル、オタサーの姫が一人いるらしいよ。
I heard that club has one 'otasa no hime' — the only girl in the group.
オタサーの姫状態だと、周りがちやほやして大変だよね。
When you're the sole girl in an otaku circle, everyone fusses over you, which can be tough.
