Серідзава Лейла

Although her name is often transliterated as "Reira", her actual name is "Layla", after Eric Clapton's famous song of the same name. She is half-American, half-Japanese, and is the lead singer of Trapnest. She also penned some of their songs. Layla's friendship with her band comes all the way back to her elementary school days, starting with Takumi Ichinose. The two met when Layla and her mother moved to Japan. Often criticized by the neighborhood because of her then-vague understanding of the Japanese language, Takumi was asked to befriend her.

The two stuck together throughout their childhood, mostly teaching each other about their first language - Reira learned more about Japanese, while Takumi learned more about English.
