Kinjiro Takehara / Joji Takehara / Gozyu Eagle

Kinjiro Takehara, better known as Gozyu Eagle, is a high-energy, party-loving university student who is more agile than anyone else. Outwardly wild and carefree, he is estranged from his family but doesn't let that bother him. Despite the flamboyant attitude, Kinjiro is actually very serious and hardworking - he wants to change himself and pursues the party life as a way to embrace freedom.

But the truth is even wilder: Kinjiro is actually Joji Takehara, an 87-year-old grandpa who once lived with strict discipline and disapproved of wasting time. After the loss of his wife, Joji began to admire those who live freely. One day while tending to his bonsai tree, he discovered the mystical GoZyuEagle Ring and was transported to the dimensional space of the Tega Sword. There, he made a wish - to relive his youth as a party person - and formed a Ring Contract. The wish granted him a rejuvenated body, allowing him to transform into Kinjiro.

This transformation requires him to consume egg-based dishes like omelets to maintain his youthful form. If he fails to do so, he reverts to his elderly self. Despite the comical transformation mechanism, Joji's journey reflects deep themes of regret, self-discovery, and the desire for personal reinvention.

He is portrayed by Jin Matsumoto, with suit acting by Shogo Teramoto (known for Kamen Rider Saber's Zooous and Hachi Ohger).
