The Gymnastics Samurai - S01

At the height of his gymnastics career, Joutarou Aragaki, nicknamed Samurai for his signature hairstyle, suffers a shoulder injury after his wife's death. Five years later, he is still pushing his body to its limits as a member of the Japanese gymnastics team. But his intense training is not producing any progress. His coach, Noriyuki Amakusa, tells him he should retire. With his lively and supportive nine-year-old daughter, Rei, Joutarou takes a trip to Ego Wonderland to break the bad news to her. Their outing ends with a strange encounter with a peculiar self-proclaimed ninja named Leonardo. He follows them home and interrupts every attempt Joutarou makes to tell his daughter. After learning that Leonardo hopes to see him do gymnastics again, Joutarou stuns Japan by announcing that he is not retiring. He commits himself to the biggest challenge of his career to prove that he still belongs in the gymnastics world.
