Seiko Ayase: zodiac sign and birth chart
Seiko Ayase has no canon birthday. Neither the manga nor the anime give one. Read from her personality, she's a Taurus. Sun, Moon, rising, Mercury and Mars all sit in the same sign: Momo's grandmother, the medium with zero patience for nonsense, who swears, grumbles and scares anyone.

NEBO's take
No birthday in canon. Her personality says Taurus.
We ran Seiko 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 earth almost all the way across: stubborn, solid and impossible to rush.
Canon

Taurus doesn't move. Seiko faces yokai with the same flat stare she gives everyone else.
- Moon
CanonNot in canonNEBO's takeTaurus
A Taurus Moon wants a stable home. Momo lives with her, and she takes Okarun and the rest of the weird crew under her wing.
- Rising
CanonNo birth timeNEBO's takeTaurus
First impression: a small woman with a big scowl, and the kind of presence that makes ghosts back up.
- Mercury
CanonNot in canonNEBO's takeTaurus
Taurus Mercury says it blunt. She swears, grumbles and tells everybody exactly what she thinks.
- Venus CanonNot in canonNEBO's takeNo clear pick
- Mars
CanonNot in canonNEBO's takeTaurus
Taurus Mars is calm and exact. She sets up a protective circle in seconds and leaves a spirit nowhere to run.
What canon does give: a woman who has dealt with ghosts her whole life and won't be impressed by yours. A Taurus answer is to stand firm and finish the job.
How she shows up
