Neru, also known as Oshiire-P (押入れP), is a producer who mostly works with Kagamine Rin and Len. His works are mainly rock, and in many cases, the lyrics to his songs are somewhat dark.
His first hit was "Abstract Nonsense", which is his first song to reach over 100,000 views, though his most notable one would be "Tokyo Teddy Bear", his first song to reach 1 million views.
His -P name, Oshiire-P, comes from a comment Neru made, "I slept in the closet and used Kagamine Rin and Len." "Closet" (Oshiire) later became his P name, though he mainly uses "Neru" in his songs or video descriptions.
He was born on the 10th of August in 1992. (Age 25)
