永遠に幸せになる方法、見つけました。 (Eien ni Shiawase ni Naru Houhou, Mitsuke Mashita.)
This song also became very popular, with over 1,000,000 views to date.
The song begins with a new bride talking of how she has found the way to the 'town of hope' where the ritual takes place, where she wishes to obtain a way to live forever. The second part of the song shows similarities with a game show, where the host says she will grant the bride's wish in what is called 'The Original Sin Game.' The bride must recite a sequence of words correctly.
It is implied that although the bride gained the power to live forever, she is unhappy with immortality, possibly caused by the groom's death. She returns to the town, repeats the ritual and wishes for eternal happiness. She is transformed into a zombie and in that way, remains serene forever.
Utata-P was inspired by voodoo to turn Miku into a Voodoo Goddess.
