Bokene / Bokeneko (c) Skeyi.
.ust (c) Haloheroine
Original song by Kagamine Len.
Genderbend of the second Skeyiloid, Bokene.
Named Bokeneko (the Kanji for "ko" is "child"), just add the g-10 flag.
I edited the pitch of the karaoke to get a fast and slightly lighter beat suitable for a girl-ish voice.
I also changed all the "boku" (masculine/humble way of referring to oneself in Japan) to "watashi" (feminine or polite way of referring to oneself in Japan).
Nonetheless, the .ust belongs to Haloheroine.
