The world of anime is bursting with colorful and intriguing characters of all types, and fans can sort and organize these characters with many different metrics, from their Myers-Briggs personality types to their Dungeons & Dragons alignment and, of course, the twelve astrological signs.

Many anime characters have a confirmed date of birth, and this makes it easy to see which character has which sign, from Aries and Scorpio to Capricorn and Gemini. March 20th to April 19th is the realm of Aries, a bold and decisive fire sign, and these ten anime characters live up to their Aries sign one way or another. They truly have a heart of fire.

10 Annie Leonhart - March 22nd (Attack On Titan)

Annie Leonhart with a blue sky background in Attack On Titan.

Annie Leonhart is the Female Titan wielder, though in human form, she rarely acts like an Aries at all. She is notably passive and withdrawn, since the cynical and bitter Annie doesn't see much point in fighting for any particular cause. Annie will, however, fight fiercely to defend her foster father.

Annie is more like an Aries in combat, becoming a reckless and aggressive Titan Shifter that can take on dozens of Scouts and win. Annie never experienced the self-doubt that Reiner Braun did, and she boldly moved forward with her mission without fear, like a true Aries.

9 Erina Nakiri - March 23rd (Food Wars!)

The gifted Erina Nakiri always had a good heart, but she rarely had a chance to show it. She spent years under her single father's thumb, afraid to express herself or design her own future as a chef. Erina eventually got away from him and began her education at the Totsuki culinary school.

Erina is well-known for being a short-tempered tsundere, and over time, she learned to proudly assert herself and stand up to Azami Nakiri. She also became Totsuki's dean and threw herself tirelessly into that endeavor, as a bonafide Aries would.

8 Yusuke Urameshi - March 26th (Yu Yu Hakusho)

Yusuke Urameshi from Yu Yu Hakusho

Yusuke Urameshi is a punk with a good heart, and he is often considered a model shonen protagonist for the ages. He risked his life to save a child from a speeding car, and then he became an underworld detective with a new lease on life. He is also a wildly talented and powerful martial artist.

Personality-wise, Yusuke is a classic Aries, a bold and decisive boy who always knows what he wants and how to get it. He is kind to his friends and family and merciless to his enemies, and he always loves a good challenge. He's an Aries who just can't sit still.

7 Akitaru Obi - March 27th (Fire Force)

Akitaru Obi commands the 8th company of the Fire Force, even though he doesn't have an ignition ability of his own. Akitaru is a bold and fearless fighter who can use his physical strength and a variety of specialized equipment to take on Infernals, and he has some leadership qualities, too.

In the office, Akitaru is somewhat laid-back and unambitious for an Aries, but he takes his duty seriously and can switch to battle mode in an eyeblink when the alarm sounds. Once business has begun, nothing can stop him.

6 Mashiro Kuna - April 1st (Bleach)

Mashiro Kuna is one of the eight masked Visoreds, or ex-Soul Reapers who can don Hollow masks to boost their power in combat. Mashiro and her fellow Visoreds never asked for this, but they might as well make the most of it.

Mashiro is the happiest and most energetic of the Visoreds, as a true Aries, and she will enthusiastically jump into any battle or sign up for any adventure without hesitation. She's not as high-strung or tense as some Aries can be, though.

5 Ai Hayasaka - April 2nd (Kaguya-Sama: Love Is War)

ai hayasaka

Kaguya's maid and best friend, Ai Hayasaka, rarely gets a chance to truly assert herself as a fiery Aries, though her passions do run deep despite her cool exterior. Ai often serves as Kaguya's exasperated sounding board, and she isn't afraid to throw sharp verbal barbs at her mistress.

Ai sometimes takes the initiative, Aries-style, and shows the indecisive Kaguya how to pursue Miyuki properly. Ai is also known to be passive-aggressive and snide, which is Kaguya-Sama's version of being a fierce Aries.

4 Yammy Llargo - April 3rd (Bleach)

Yammy Llargo, the 10th Espada, is another Bleach character born under the fire sign Aries. That is, he was probably born on that date as a human, then died and became a Hollow before becoming an Arrancar. Most Arrancars and Hollows don't care about their birthdays and horoscope, but it can still be an insightful topic.

Yammy is a villainous Aries to the bone, an aggressive and fierce warrior who recklessly pursues glory and bloodshed in battle without hesitation. In fact, his zanpakuto is named Ira, or "anger," and his released form grows bigger and stronger based on his rage, just like the Incredible Hulk.

3 Erza Scarlet - April 7th (Fairy Tail)

Erza Scarlet is an S-rank wizard of the famed Fairy Tail guild, and she has been a brave and decisive hero since her girlhood, when she helped lead a revolt of child slaves and escape the Tower of Heaven project. She has been loyal to the Fairy Tail guild and her friends ever since.

Erza is a true Aries, a heroic and proud fighter who won't ever back down from any challenge, especially not on the battlefield. She also as a passion for acting and keeps accepting roles in theater despite her poor skills. She is brave to keep up this hobby.

2 Gabi Braun - April 14th (Attack On Titan)

Gabi Braun is the cousin of Reiner Braun, the Armored Titan, and is fiercely determined to obtain the Armored Titan for herself someday. She is one of several trainee Warrior candidates in the Marley Empire, and her heroic and reckless ways make her a rising star in the eyes of Marleyan officers.

This young Aries boldly took on an entire enemy train and destroyed it with a simple trick, and she also took it upon herself to climb aboard an airship and shoot her enemies inside, claiming the life of Sasha Braus. Gabi isn't easy to like, but she is easy to admire as a hotheaded Aries.

1 Giorno Giovanna - April 16th (JoJo's Bizarre Adventure)

Giorno from Jojo's Bizarre Adventure

Giorno Giovanna is the hero of the Golden Wind story arc, and he claims to have a great dream worth risking his very life for. He has learned to look after himself, and he will boldly take what he wants, when he wants it. He's a bit of a street punk, but not a true villain by any means.

Giorno soon joined Bruno Bucciarati's squad, and he was absolutely fearless in battle. He also isn't afraid to assume a leadership role in a fight, even if Leone Abbacchio and Narancia don't always appreciate that. He also fiercely beat down the villainous Cioccolata without mercy to end their fight.
