Shirow Miwa (illustrator, designer)
Shirow Miwa is a manga artist and illustrator. He's best known for the manga series Dogs, but he has also contributed illustrations to many tribute books and magazines, such as Square Enix's Monthly Shonen Gangan. Sometimes publishing his works under the circle name "m.m.m. + Gee", Shirow is an official member of Supercell.
Huke is a Japanese illustrator who is widely known for his ever popular, original character, Black★Rock Shooter, and being a part of Supercell. His character was a huge inspiration to Supercell's lead member Ryo, who wanted to use huke's design to create a song and music video by the same name, Black★Rock Shooter. Soon enough, this collaboration led to many opportunities for both parties, as the Black★Rock Shooter Universe expanded, receiving an animation adaption and other merchandise releases.

119 was the second member of Supercell, the first being Ryo. Originally, 119 was the illustrator of the Hatsune Miku design that Ryo used in the PV for the song "Melt". As he used it without 119's permission, Ryo apologized. 119 though found great interest in the "Melt" PV Ryo had made and began working with him, thus forming Supercell. In the current, 119 retired from Supercell, but is assumed to be still active.
