Lời bài hát: Naruto. Other. Natsuhiboshi Lullaby.

Natsuhiboshi, naze akai?
Yuube kanashii yume wo mita.
Naite hanashita.
Akai me yo
Natsuhiboshi, naze mayou?
Kieta warashi wo sagashiteru
Dakara kanashii yumewo miru
Natsuhiboshi, naze akai?
Yuube kanashii yume wo mita.
Naite hanashita.
Akai me yo
Natsuhiboshi, naze mayou?
Kieta warashi wo sagashiteru
Dakara kanashii yumewo miru
