Ai Hoshino: zodiac sign and birth chart
Ai Hoshino has no canon birthday. Neither the manga nor the anime gives one. Read from her personality, she's a Scorpio with a Leo Moon and rising: the idol who owns every stage and keeps her real self locked away. A Libra Venus is the smile that works on everyone.

NEBO's take
No birthday in canon. Her personality says Scorpio.
We ran Ai through the same model that matches people to characters in the app, and looked at which chart gets her most often. It reads her as a deep, guarded Scorpio under a glowing Leo surface.

Scorpio is what she never shows: deep, private and intense. The smile is only the cover.
- Moon

A Leo Moon needs the crowd and the spotlight, and feels most herself in the light.
- Rising

No birth time in canon. First impression: someone so bright that the crowd forgets everything else.

- Venus
CanonNot in canonNEBO's takeLibra
Libra Venus is charm and grace: she makes each fan feel she sees them personally.
- Mars
CanonNot in canonNEBO's takeLeo
Leo Mars is the stage performer's drive, bold and effortless.
What canon does give: an idol who believes a lie can be a form of love. A Scorpio answer is the hidden depth, with Leo as the stage she shines on.
