Ie no Ura de Manbou ga ShinderuP (家の裏でマンボウが死んでるP) also known as uramanbou or simply manbou-p, is a producer notable for making humorous songs usually in a storytelling format. Uramanbou's first work, "Ie no Ura de Manbou ga Shinderu" (A Sunfish is Dead at the Back of my House), gained a lot of attention to where it became his P name.
His older sister, Manbou no Ane, illustrates his songs and has stated that her brother's strange lyrics comes out from a "girly hobby" (reading shoujo manga).
During the major debut of his album "My Colorful Confuse" with SPEEDSTAR RECORDS, uramanbou re-introduced himself as Takahashi You (タカハシ ヨウ), now the name credited for the music and lyrics. Ie no Ura de Manbou ga ShinderuP is now the namesake of the brother-sister unit.
As a celebration for his third year anniversary as a producer, he produced "Fools Among the Stars" (星のとなりの空け者), a trilogy of songs based on Tanabata's Legend of Orihime and Hikoboshi. It is comprised of the songs subtitled "Orihime/Vega", "Hikoboshi/Altair", and "Kappa" sung by VY1, VY2, and GUMI respectively.
This producer has also released works in the Vocaloid-P Data Series series and contributed tracks to the Music Study Project.
