足りないもの (Tarinai Mono)

Background
"Tarinai mono" is a song composed by Hidarigawa-P, and is her 24th Vocaloid original work uploaded to Nico Nico Douga, her first to include Lapis (as a chorus; not as an original song). Hidarigawa-P stated in her description that she imported Len and Rin's Append voicebanks to Vocaloid 3, using the V3 import.

Uploaded on April 15th, at the same day Hidarigawa-P's other work "Cosmetic Love!!" was also uploaded, overall, "Cosmetic Love!!" was more notable than Tarinaimono. This song was later remastered in Hidarigawa-P's first album "HakkoRinLen".
