どうしてこうなった (Doushite Kou Natta)

Background
This song was composed for Hatsune Miku -Project DIVA- Arcade contest. The author seems to have applied for the contest as a joke and had the slightest idea that this denpa song with pointless lyrics would win the contest, but this song was adopted for the game.

How'd it get to be like this for Ugongerge?
