＊サヨナラ、ワールドエンド。 (*Sayonara, World End.)

Background
An exclusive bonus track from the "Vocaloid wa Shuumatsu Tori no Yume o Miru ka?" album, this song is a sad "answer song" to "＊Hello, Planet." In this song, Miku recalls her old memories and tries to continue her journey. She says good-bye to everything that she loved and to her memories. Finally, wishing to meet with her beloved one again she says goodbye to the little sprout in the flowerpot, to her own tears and to this world.

The song ends with the same phrase from "＊Hello, Planet.", 「あいたかったの"キミ"に オハヨーハヨー」 (Aikatatta no kimi ni ohayō-hayō) hinting that she finally meets with her beloved one in the next life.
