Jin Hakariya, also known as Sazer-Dail, is a character who serves as a member of the Wind Tribe. His zodiac sign is Libra. Outside of his duties as a warrior, he works as a fashion designer. As the third member to join his tribe, Jin’s initial approach to his role differs notably from a sense of duty; instead, he is driven by a desire for excitement and enjoyment. He delights in having his powers and is prone to playing around with them, always seeking a new challenge.

In terms of personality, Jin is characterized by a fun-loving and competitive nature. He is not initially devoted to the serious mission of the Sazers, but rather sees his abilities as a source of entertainment. Despite this carefree attitude, he holds a genuine appreciation for teamwork. This appreciation becomes a key part of his development, as he is convinced by his fellow Wind Tribe member, Ryoko Amemiya, that all the Sazers must unite and function as one cohesive team. This realization marks a shift from his self-interested beginnings to a more cooperative and reliable ally. He often has a tendency to appear in critical moments to help balance the odds in a fight. In the narrative, Jin is recruited by a figure named Karin Saeki, who is later revealed to be an alien in disguise. Karin manipulates the Wind Tribe into believing the other Sazer tribes, particularly the Flame Tribe, are their enemies. This deception leads Jin and his comrades into conflict with the other warriors. However, as Ryoko grows suspicious of Karin and leaves the group, Jin follows, eventually uniting with the other Sazers to uncover the truth and defeat the true enemy.

Jin’s key relationships are primarily with his fellow Wind Tribe members. He works alongside Ryoko Amemiya (Sazer Velsou) and Akira Dentsuin (Sazer Remls). The trio collectively controls their tribe’s Chouseishin, a giant mechanical warrior named Dorcrus, which they can summon when their powers are combined. Jin’s initial reluctance to take his mission seriously is tempered by his interactions with Ryoko, whose conviction helps him see the value in teamwork. As the story progresses, he becomes a trusted member of the larger Sazer alliance, leaving behind his initial manipulative recruitment to fight as a genuine hero. He later appears alongside other Sazer teams to face new threats.

When Jin transforms using his Knuckle Riser device, he becomes the wind warrior Sazer-Dail. His armor is purple in color and its design is shaped after a stag beetle. As a fighter, he possesses enhanced physical capabilities. His primary weapons are a pair of axe-like tonfas known as the Axe Tagger. With these weapons, he can perform his finishing attack, a technique called the Whirlwind Strike, which generates a powerful horizontal tornado blast to strike his opponents. Together with the other Wind Tribe members, he can combine their powers to summon and pilot their giant Chouseishin, Dorcrus.
