Here are the main anime characters celebrating their birthday today.

Kafka Hibino (Kaiju No. 8)

Kafka Hibino is the protagonist of "Kaiju No. 8." From a young age, he dreamed of joining the Japan Defense Force due to a promise made with his childhood friend, Mina Ashiro. While Mina achieved great success and became a superstar ace of the Defense Force, Kafka failed to pass the entrance exams and, at 32, exceeded the age limit, thus shattering his dream. At the beginning of the main story, Kafka works as an employee at Monster Sweeper, a kaiju cleanup company that handles the corpses of kaiju defeated by the Defense Force.

Kafka is a kind-hearted and good-natured person who can't ignore someone in need. As a kaiju cleanup worker, he is highly skilled, possessing the knowledge and experience from his demolition work, which makes him exceptionally competent despite his complaints about the tough job. His talents are so recognized that his boss believes Kafka would have made an excellent Defense Force officer. Even after joining the Defense Force, Kafka uses his demolition experience to understand kaiju behavior on-site, preventing their proliferation, demonstrating a unique strength born from his past work.

Pieck Finger (Attack on Titan)

Pieck Finger is a member of the "Warriors of Marley" and the true identity of the "Cart Titan." Due to her prolonged maintenance of the four-legged "Cart Titan" form, she often jokes about forgetting how to walk on two legs when she reverts to human form. Although she often appears lethargic, she is highly regarded by the Marleyan side for her judgment skills. During the aforementioned meeting, her calm assessment of the situation earned praise from Zeke, who commended her with, "As expected of Pieck-chan."

Pieck has a strong sense of camaraderie with her fellow "Warriors of Marley," whom she has fought alongside. Her guiding principle seems to be fighting alongside her comrades until the very end.
