Hibiki, also known by the alias Sonic Sword, is a character from the anime Hand Shakers. He is a 30-year-old man with black hair, brown eyes, and a height of 165 centimeters, possessing a somewhat stocky build. His birthday is on March 3rd. Hibiki is the dedicated manager and Hand Shaker partner of the young idol, Kodama, and together they are known as Team Sword.

Hibiki’s background reveals a man who made a dramatic life change driven by his devotion to Kodama. He was originally a businessman, but he chose to leave the corporate world behind to become Kodama’s manager, fully supporting her career as an idol. His personality is marked by an intense and unwavering admiration for her. He is deeply moved by Kodama’s words and actions, often to the point of tears, and he makes it a point to praise her profusely. He treats her statements as if they are wise proverbs to be cherished and remembered.

His primary motivation is the success and well-being of Kodama. His role in the story is directly tied to her, as he acts as both her protector and her supporter. As a Hand Shaker, he fights alongside her in the supernatural battles against other pairs. His most notable ability in combat is the use of a weapon referred to as a lightsaber or a sonic sword. His key relationship is exclusively with Kodama, and his entire character arc revolves around his loyalty and service to her. Unlike many characters who undergo a significant internal transformation, Hibiki’s development is expressed through the reinforcement of his established traits, showing the lengths to which his dedication drives him to fight and sacrifice for the sake of his partner.
