Here are the main anime characters celebrating their birthday today.

Rin Itoshi (Blue Lock)

The current top ranker in Blue Lock.
He is someone the protagonist, Yoichi Isagi, is highly aware of.
Rin is characterized by his black hair and notably long lower eyelashes. He is the younger brother of the world-class player Sae Itoshi, who also plays a significant role in the story.

Though he exudes a cool demeanor, his personality is arrogant, domineering, and incredibly self-centered—a true super-egoist. His confident plays and strong words stand out, and his attitude stems from his unwavering dedication and self-confidence in his abilities. In his free time, he engages in self-practice, and his routine after matches and training includes cool-down yoga and meditation, highlighting his unparalleled discipline in the story.

The reason Rin has become such an egoist appears to be connected to his past with his brother, Sae Itoshi, who has risen to global fame...

Itsuka Kendo (My Hero Academia)

A female student in Class 1-B of the Hero Course at U.A. High School. She is the class president.
She is known for her orange side ponytail.

As the class president of Class 1-B, Itsuka is a big sister figure who brings together troublemakers like Monoma and Tetsutetsu.

She has a tomboyish, compassionate personality and is known for her bright and commanding presence, leading her class with ease. Itsuka is the type to give her all once she sets her mind on something. Her decision-making skills are highly regarded, and she often takes on the role of strategist during combat training sessions.

Her quirk is called "Big Fist."

She can enlarge both of her fists to an immense size, large enough to completely envelop the small-statured Kodai in her hands.

Although her quirk may seem plain at first glance, combined with her proficiency in martial arts, her abilities are nothing to be underestimated.

Her powered-up fists can destroy a metal shield in a single blow, and the force is strong enough to send the person behind the shield flying.
