Lil'B is a Japanese female two-member pop group made up of vocalist Mie and rapper Aila. Debuting in 2008, the duo first appeared with "Orange," which was used as the 15th ending theme for Bleach and immediately connected them to the anime music scene.
The group is best known for "Kimi ni Utatta Love Song," a single that reached the top of the RIAJ monthly ringtone chart in 2008. That success helped establish Lil'B as a notable name among Japanese pop acts with a strong presence in anime-related releases.
Musically, Lil'B balanced melodic pop with rap-driven sections, using the contrast between Mie's vocals and Aila's rap to create a compact and distinctive two-voice style. This approach gave their songs a clear identity and made them especially effective for ending themes and emotional single tracks.
Another important anime tie-in came with "Tsunaida Te," which was used as the third ending theme for Fullmetal Alchemist: Brotherhood. The group's name is said to come from a contraction of "little" and the first letter of "betray," a detail that reflects the duo's concise, memorable branding.
