ブリリアントワールド (Brilliant World)
From December 24th to January 5th, you’ll be able to purchase the single song plus an additional lyric booklet through iTunes for ¥250, but it doesn’t appear that it’s available overseas as of yet. Continue checking iTunes to see if it’s available in your country! But be sure to get it quick, because it’ll be gone in two weeks!
