Ui Ui: zodiac sign and birth chart
Ui Ui has no canon birthday. Neither the manga nor the anime give one, so his chart is NEBO's take, read from his personality. It says Pisces: calm, quiet and devoted to one person. Mei Mei's younger brother, polite and handsome, with a loyalty that is a little scary in scale.

NEBO's take
No birthday in canon. His personality says Pisces.
We ran Ui Ui through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as water first: Pisces Sun, Moon, Mercury and Mars, with Cancer Rising.

Pisces gives itself to one person completely. Ui Ui's devotion to Mei Mei is almost obsessive.
- Moon

Pisces Moon is our take: absorbed in someone else's feelings and needs.
- Rising
CanonNo birth timeNEBO's takeCancer
No birth time in canon. First impression, Cancer style: polite, quiet, keeping his distance until he's sure you're no threat to his sister.
- Mercury
CanonNot in canonNEBO's takePisces
Pisces Mercury is quiet and soft-spoken. He says little and lets what he does speak.
- Venus
CanonNot in canonNEBO's takeAries
Aries Venus loves hard and fast. Whatever Mei Mei needs, he moves immediately.
- Mars
CanonNot in canonNEBO's takePisces
Pisces Mars doesn't fight head-on. His Teleportation moves himself and others within his territory, giving the team a chance to escape a trap.
What canon does give: a brother who almost never fights himself and stays at his sister's side. A Pisces answer is devotion with no limit.
