Mrs. Green Apple

Singer Omori started creating music when he was in 6th grade, but did not form a band till 2013. Mrs. GREEN APPLE was formed in the spring of 2013 with 4 members: Omori, Wakai, Yamanaka, and a former member who was a bassist. Later, Omori invited Fujisawa, and Mrs. GREEN APPLE became a 5-member band.[4]

On February 4, the band released their demo CD, 1st Demo, at concert venues where they played.[5] The demo included two songs, "リスキーゲーム(Risky Game)" and "恋と吟(Koi to Uta)." Just a few months later, their first mini album, Introduction, was released at the band's first self-planned event. The gig, held on July 5 at Shibuya LUSH, sold out and was also the place where the former bassist announced that he would leave the band.

2015 marked a huge change for Mrs. Green Apple. On February 18, the band released their first nationally distributed CD, Progressive. A month later, on March 26, they announced that they would debut from a major label at their third self-planned event, which also sold out.[6] The group's mini album Variety, was released by EMI Records on July 8. That summer, the group went on to perform at some of the most popular music festivals in Japan, such as Rock in Japan Festival, Rising Sun Rock Festival, and Rush Ball. In December, the group released their first single, "Speaking." The song was chosen as the ending theme song for the anime Yu-Gi-Oh! Arc-V.[5][6]

Mrs. Green Apple released their first full album, Twelve, on January 13, and made many appearances on television. The group went on their first national one-band tour from March 1 to April 10 of the same year.[6]
