This song describes Miku introducing herself to the world. It is a denpa song, and thus the title Miku Miku ni Shite Ageru (I'll make you Miku-Miku-ed) carries no specific meaning in Japanese. Thus, what the title actually means is a subject of disagreement among fans. However, the term was derived from ぼこぼこにしてあげる (boko boko ni shite ageru), which means I'll beat you up. One of the prevailing interpretations among the Japanese fandom is I'll make you obsessed with Miku, conveying the idea that Miku strikes fans' hearts with her voice. Similar expressions are みくみくにされる (Miku Miku ni sareru) (I'm Miku-Miku-ed), フルみっくにされる (furu Mikku ni sareru) (I'm Miku-Miku-ed to the full extent) and so on). It is commonly said to newcomers in the VOCALOID fandom as a welcome, or to make them a VOCALOID fan by replacing Miku with another VOCALOID name, implying that they will turn you into an overall VOCALOID fan.
