Jack the Ripper: zodiac sign and birth chart
Jack the Ripper is a Gemini, born on June 1. Canon gives no year, so the Moon and the rest of his chart are NEBO's take. Gemini fits the lanky, cocky Green Mantis captain who argues with everyone, hates boring talk and cuts to the chase.

NEBO's take
Canon says Gemini. Our model says Sagittarius.
We ran Jack 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 Sagittarius first: blunt, restless and always up for a duel.

Canon's Gemini is the one who argues with everyone and gets bored in a second. Sagittarius is the one who says it to your face.
- Moon
CanonNo birth yearNEBO's takeSagittarius
Canon gives no year, so the Moon is our take. Sagittarius Moon wants room to run, and no boring conversations.
- Rising
CanonNo birth timeNEBO's takeSagittarius
No birth time in canon. First impression: lanky, cocky and already grinning at your weak spot.
- Mercury
CanonNo birth yearNEBO's takeSagittarius
Sagittarius Mercury has no filters. He is direct in a way that startles even other captains.
- Venus
CanonNo birth yearNEBO's takeScorpio
Scorpio Venus loves intensely and loyally. In a fight for the Kingdom, he is one of the most reliable blades.
- Mars
CanonNo birth yearNEBO's takeAries
Aries Mars attacks first. Slash magic cuts through spells, shields and even the magic around him.
Where we agree: both signs are quick-witted and restless. Gemini argues for fun, Sagittarius swings for the horizon.

What zodiac sign is Jack?
Gemini. The official Black Clover site gives Jack's birthday as June 1, and Gemini runs from May 21 to June 20.
When is Jack's birthday?
June 1. Canon never gives his birth year, so a full birth chart can't be calculated.
Is Jack a Gemini?
Yes, by his canon birthday. Quick, restless, argumentative and never boring: he is Gemini with a blade. Our personality model adds a lot of Sagittarius on top, the part that heads straight for the goal with no detours.
What is Jack's Moon sign?
Unknown in canon, because the official profile gives no birth year. NEBO's take, built from his personality, puts the Moon in Sagittarius.

By chart, Luck Voltia, Julius Novachrono and Mereoleona Vermillion. Sagittarius Moon and Aries Moon: they calm down the same way, no translation needed.
