我想問下...

短片既背景音樂是 Do As Infinity 既 Rakuen(楽園)

"Rakuen" (楽園) is Do As Infinity's eighteenth single, released in 2004. This is their first and only single to reach the top 3 in the Oricon charts. This single is available in two editions, CD, CD+DVD, each with a different cover. It was also used as an ending track for the fourth Inu Yasha movie.
