Biography
Hayashi used to be an athlete for Men's Rhythmic Gymnastics and then he became fascinated by background score when selecting gymnastics floor music. Although he had no experience in producing music before, he started learning to compose himself during college years. He sold one of his pieces for 5000 yen to junior players as their gymnastics background music, and progressively more orders came after other teams heard his works. After graduation, he became an apprentice of Kobayashi Hideo to learn beatmaking and meanwhile, he also began making background music for dancesport.

He then joined the music agency Legendoor in 2009 with his first major work being Triangle with Sawano Hiroyuki, and Robotics;Notes with Tachibana Asami and Abo Takeshi being his first anime work. In March 2021, it was announced that Hayashi's contract with Legendoor will be terminated as of October 2021 after 12 years, with him establishing his own company named Hayashi Factory and working as an independent composer from April 2021.
