When I was told to do the arrangement for Hatsune Miku's「Butter Fly」, I was worried for sometime as I was unsure whether itthat if was fine to let me handle the arrangements as I'm not from the Digimon generation, but its rare to be given a chance to be involved in the "music" aspect of Digimon as it is an important element of the Digimon World, therefore I was honored to take this oppurtunity.

To heighten up the spirit of celebrating the 20th anniversary, I will attempt to review all the past works before the 2020 Movie comes out. The first meeting with Digimon, I'm getting excited.
