One of the best things about anime characters can be their wildly colorful hair colors. Blond, brown, and black simply aren't good enough, so creators push for more eye-catching colors. Green, blue, orange, and even red hair colors can easily be seen on some of the most popular characters out there.

In fact, shonen shows are infamous for having their protagonists with not only eye-catching hair colors but often odd-looking hairstyles. While there are many popular blue-haired anime characters out there, this article will only focus on the ones that used to be popular but were basically forgotten with the passage of time.

Nagisa Shiota (Assassination Classroom)

Nagisa Shiota is one of the many protagonists of the dramedy anime show Assassination Classroom. In fact, this anime made headlines for not only having a huge ensemble cast but being able to justify the existence of every single one of them in the show.

Nagisa easily one of the fan-favorites, right alongside Karma. With his short blue hair and his androgynous appearance, he was often mistaken for a girl. He is shown to be shy and reserved but can become surprisingly bloodthirsty on the battlefield.

9/10 Rin Okumura (Blue Exorcist): The Son Of Satan

Rin Okumura (Blue Exorcist)

For the son of Satan, one wouldn't expect it to be a blue-haired and blue-eyed teenage boy who's not as smart as the average person. In fact, his younger twin brother Yukio is forced to play the role of the elder brother and often, Rin's father. Yet, despite all his flaws, Rin Okumura is loved by all.

He hates Satan from the bottom of his heart for killing his adoptive father. He enrolls at the True Cross Academy to become an Exwire to gain enough knowledge and skills so that he can ultimately defeat Satan.

Tokiya Ichinose (Uta No Prince-Sama)

As the one anime that took the world of reverse harem by a storm, Uta No Prince-Sama's name isn't remembered by many western fans. The anime featured a sea of beautiful bishies, where Tokiya Ichinose was someone who easily stood out.

With his dark blue eyes and piercing gaze, Tokiya was an obvious choice for the idol group ST☆RISH. He is calm, collected, and loves doing everything perfectly. Despite being immensely talented, his peers can often be seen accusing him of singing without true emotions.

7/10 Tetsuya Kuroko (Kuroko's Basketball): The High School Basketball Star

Tetsuya Kuroko (Kuroko's Basketball)

Despite possessing a mane of shocking blue hair on his head that can be seen from a mile away, Kuroko was often described as "invisible" by his own teammates.

In the game of basketball, this often came to his advantage since he was able to misdirect his opponents and pass on the ball to his own teammates. However, Kuroko's inability to express himself often came in his way of making genuine bonds with his teammates.

6/10 Sonoda Umi (Love Live!): The Leader Of The Lily White

Sonoda Umi (Love Live!)

This leader of the Lily White loves the color blue. Her hair is obviously blue as well, and since it's never indicated she colored it, it is assumed it is her natural hair color.

As a second year student at the Otonokizaka High School, Umi is one of the many main characters of the ensemble music anime Love Live!. Despite being extremely intelligent and book smart, she has a reserved personality which is often reflected in her disciplined attitude.

Lancer (Fate/stay Night: Unlimited Blade Works)

While there have been many Fate anime out there which may leave new fans confused, the overall outline and appearances of characters remain the same.

While Lancer's hair color might differ from anime to anime (because of different studios adapting different Fate anime), his dark blue hair has remained constant. Fierce but kind, experienced and wise, Lancer is easily one of the most popular characters from the Fate series.

4/10 Konata Izumi (Lucky Star): The Eccentric Otaku

3/10 Aqua (Konosuba): The Powerless Goddess Of Water

Aqua (Konosuba)

Aqua used to be the Goddess of water with a lot of knowledge and power. In the Fantasy World, she has none of her powers and is next to useless for Kazuma, who finds it hard to survive in this new world.

Aqua is carefree, cheerful, and overfriendly. Despite her stunning blue-haired visuals, her behavior often gets her and Kazuma into a lot of trouble, especially when she decides to speak exactly what is on her mind.

2/10 Ciel Phantomhive (Black Butler): The Sharp & Cunning Eye-Patched Kid

Ciel Phantomhive (Black Butler)

1/10 Kamina (Tengen Toppa Gurren Lagann): The Arrogant & Hot-Headed Hero

Kamina from Tengen Toppa Gurren Lagann

Arrogant, hot-headed, emotional, and air-headed – these are the qualities that describe Kamina the best. He enjoys being praised or having his accomplishments recognized, and he often addresses himself as the Mighty Kamina.
