Heathcliff: zodiac sign and birth chart
Heathcliff has no canon birthday. Neither the novels nor the anime give one. Read from his personality, he's a Leo: the commander with a huge shield and a unique Holy Sword skill, who leads from the very front and tells almost nobody what he thinks. Aries Moon and rising keep him at the head of the line.

NEBO's take
No birthday in canon. His personality says Leo.
We ran Heathcliff 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 fire first: a Leo Sun with Aries Moon and rising, a leader who stands where everyone can see him.

Leo takes the front of the room. Heathcliff leads the Knights of the Blood Oath himself, in red and white, shield first.
- Moon

Aries Moon acts at once. When Kirito shows his second sword, Heathcliff's answer is a duel.
- Rising

No birth time in canon. First impression, Aries style: a calm commander in red and white who steps forward before anyone else.
- Mercury

Virgo Mercury notices the detail. He sees the second sword and puts it to the test in a duel.
- Venus
CanonNot in canonNEBO's takeLibra
Libra Venus loves a beautiful ideal. His great love is a castle in the sky.
- Mars
CanonNot in canonNEBO's takeGemini
Gemini Mars fights with a shield and a sword at once. The Holy Sword skill is armor and weapon in the same move.
What canon does give: a leader nobody quite figures out. A Leo answer is to hold the room with calm confidence and keep the real plan to himself.
How he shows up
Why he's like this
Leo is the sign of the leader, the big stage and the big vision. Heathcliff hits it in the way he leads from the front and how large he thinks.
First impressionAries rising
The commander up front
He leads the Knights of the Blood Oath with a huge shield and the unique Holy Sword skill, and his health bar never seems to drop below half.
