The song can be claimed by any player from the in-game Present section.","whyItMatters":"Posting a full-size 2D MV on YouTube and giving the song away through the Present section is the standard way Project Sekai extends a track past the players who already own it, and this one carries both Megurine Luka and a unit vocal.","webCardHtml":"\u003cp\u003eThe version is sung by Megurine Luka with Wonderlands x Showtime, and the lyrics and music are credited to Satsuki.
