Lil'B is a Japanese female two-member pop group formed in 2007 by vocalist Mie and rapper Aila. The duo debuted in 2008 with "Orange," which was used as the 15th ending theme for Bleach, and they were associated with Defstar Records. That early anime placement helped introduce Lil'B to listeners looking for Japanese pop groups linked to anime songs.
The group is also known for "Kimi ni Utatta Love Song," a single that reached the top of the RIAJ monthly ringtone chart in 2008, and for "Tsunaida Te," which served as the third ending theme for Fullmetal Alchemist: Brotherhood. Lil'B built its sound around melodic pop and rap, using the contrast between Mie's vocals and Aila's rap to create a compact two-voice style. The name Lil'B is said to come from a contraction of "little" and the first letter of "betray," a simple branding detail that matches the duo's concise identity.
