Kazuumi Kumagai is the vocalist and guitarist for the band Burnout Syndromes.
When he was in the first year of junior high school, he was invited to play in a band. He accepted the offer and started listening to music, writing lyrics and composing music. After joining the band he was told to play the guitar by band member Ishikawa Taiyu (石川大裕), which led him to be in charge of the guitar and vocals in the band.
On May 4, 2005 the pair Kazuumi and Taiyu decided they needed another member, so Taiyu invited Hirose Takuya (廣瀬拓哉) to be the final member of the line-up for the rock-band BURNOUT SYNDROMES. Hirose at the time had been immersed at the local game center playing "DrumMania", so he saw this as an opportunity and accepted the offer from Taiyu. After this they proceeded to officially form the band on the same date. In 2010, they temporarily suspended band activities to focus on taking exams.
Kazuumi alongside Taiyu and Takuya made their initial major debut as BURNOUT SYNDROMES with the song "FLY HIGH!!", which would be used as the second opening theme song to the Mitsunaka Susumu directed second season of the anime Haikyuu!! 2, otherwise known as HAIKYU!! 2nd Season.
