Shirahoshi: zodiac sign and birth chart
Princess Shirahoshi is an Aries, born on April 4. Canon never gives a year, so only her Sun is official and the rest of her chart is NEBO's take. Aries fits the giant mermaid who hid in a tower for ten years and still says what she feels the second she feels it, tears and all.

Birth chart
Shirahoshi's chart at a glance
Sun from the canon birthday. Canon gives no year, so the rest is NEBO's take from her character.
NEBO's take
Canon says Aries. Our model says Pisces.
We ran Shirahoshi 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 water first: Pisces Sun, Moon, Mercury and Mars, with Cancer Rising and Aries Venus.

CanonAriesNEBO's takePisces
Canon's Aries is the one who says what she feels at once. Pisces is the heart that cries first and forgives next.
- Moon
CanonNo birth yearNEBO's takePisces
Canon gives no year, so the Moon is our take. Pisces fits the princess who cries at almost anything and doesn't hide it.
- Rising
CanonNo birth timeNEBO's takeCancer
No birth time in canon. First impression, Cancer style: a shy, huge mermaid princess who is more nervous about meeting you than you are about meeting her.
- Mercury
CanonNo birth yearNEBO's takePisces
Pisces Mercury thinks in feelings. She hears sadness in a story long before the facts.
- Venus
CanonNo birth yearNEBO's takeAries
Aries Venus attaches fast and openly. The first friend from outside the tower matters a lot.
- Mars
CanonNo birth yearNEBO's takePisces
Pisces Mars fights the soft way: tears, not fists. Forgiving instead of taking revenge is her version of courage.
Where we agree: Venus. Aries loves fast and out loud, and the model keeps it. Pisces explains why the tears come first, and why she forgives instead of hits back.
