Demon Slayer has quickly become one of the world's most popular anime and manga series, and, among other things, it's known for its wide range of characters. There are comical characters, energetic characters, and even tragic characters, and they each have their own unique feelings, emotions, and personality.
A popular method of determining exactly which personality a particular person has is by using the astrology type system, which assigns them to a particular sign (such as Aries or Libra). Based on what your sign is, you might find yourself identifying more with the Demon Slayer character who best fits that sign.
12 Aries: Sabito
Sabito, Tanjiro's brief mentor, is exactly what an Aries type looks like. He's a leader who believes in himself first and foremost, but is willing to help others and, even if he can be harsh with them, ultimately cares about them and wants them to succeed.
He's quick to forgive himself for mistakes, but he can become very impulsive if he gets emotional.
11 Taurus: Inosuke Hashibira
Inosuke is a Taurus through and through. First of all, he's decidedly stubborn, but he can also be surprisingly dependable. He doesn't turn his back on others, and he doesn't give up, even in the most difficult of situations.
He also secretly appreciates it when others care about him, even if he's too proud of himself to show it on the outside.
10 Gemini: Kanao Tsuyuri
The gentle but lively Kanao is one of Demon Slayer's most expressive characters - this is because she's able to get her point across with little to no speech. She works very well as a Gemini; she's open to change, but doesn't like having to make decisions because of her past.
She's energetic, dexterous, and enjoys the company of others more than she lets on.
9 Cancer: Tanjiro Kamado
Really, it seems impossible for Tanjiro to be anything but a Cancer - he's just that pure and innocent.
He has a great love for his family and values them even above himself, he's protective of others and tries as hard as he can to keep them from being harmed, and even if he can become emotional at a tragedy, he's mentally strong and able to get past it and do what needs to be done.
8 Leo: Yushiro
Yushiro is not your average Leo, but a Leo he is. He has a fiery personality, characterized by his great love for Tamayo (the woman who saved his life by turning him into a Demon).
Because of this, he's loyal to the core, even if it means he becomes possessive and quick-tempered at times.
7 Virgo: Zenitsu Agatsuma
Zenitsu isn't the type of Virgo you usually see in media, but his character actually fits very well with the personality when you think about what makes him tick. He's extremely sensitive and fiercely dedicated in spite of the fact that he's very often anxious - and a bit of a worrier in general.
Most of the time, he has issues with self-assurance, but when he pushes himself to do something, he's going to do it.
6 Libra: Mitsuri Kanroji
The "Love Pillar" of the Hashira, Mitsuri Kanroji is the textbook example of a Libra. She finds something to like about everyone, and therefore, she much prefers making peace between others rather than taking sides in an argument.
She can be oblivious at times, but she's strong both physically and mentally and won't give up if it means helping others.
5 Scorpio: Tengen Uzui
Tengen Uzui has a lot of traits that point him towards the sign of Scorpio: he's disciplined and logical, and the first to come up with a plan.
He's a fierce fighter who doesn't rely on others, and he's good at telling a person's true intentions.
4 Sagittarius: Sanemi Shinazugawa
Sanemi definitely leans more towards the negative side of the Sagittarius traits spectrum; he's hot-headed, blunt, and argumentative, refusing to admit he's wrong even if everyone around him thinks he is.
However, throughout the series, he's been seen to showcase positive traits as well - being bold, adventurous, and even - believe it or not - charming at times.
3 Capricorn: Nezuko Kamado
Nezuko, while she doesn't speak much during the series, definitely seems to be a Capricorn. As a human, she's shown to be practical, responsible, and caring, filled with love for her mother and siblings.
Even as a demon, she shows Capricorn traits, forming strong bonds with those she cares about and becoming more and more determined to protect them.
2 Aquarius: Giyu Tomioka
Giyu Tomioka is the kind of logic-minded independent observer who more than fits the Aquarius trademark. If he has to work with someone else, he'd prefer to be the leader; he knows what he believes in and will stand by it no matter what.
He feels emotion but has trouble expressing it, and he's easily shaken by the loss of those he loves.
1 Pisces: Shinobu Kocho
Shinobu Kocho is a mystic, compassionate, and emotional person, and because of this she likely fits best with the Pisces sign. She prefers to remove her enemies with as little violence as possible - and is even able to emphasize with them at times, even if she's ultimately grounded in realism.
She can get lost in her own thoughts sometimes and finds others much easier to understand than herself.
