No need to know the world outside

"Clockwork Lullaby 2" or "Hakoniwa no Shoujo" is the second song in Clockwork Lullaby Series. The song is about the Clockworker's Doll, the vessel of Sloth and her "father", Gallerian Marlon. The Clockworker's Doll sings about how no one but her and her caretaker are in her little room, and how she will forgo learning about the outside world to sing with him. Being called "daughter" and calling her caretaker "father" in return, the girl relates how she was given multiple treasures, which are the Vessels of Sins, to compensate her for not being able to walk, including a red glass, a blue spoon, and two yellow mirrors. While her father is always kind, the girl continues to wonder about the outside world, and observes the objects in her room mocking her, claiming she is the same as them. The girl vows to stay inside and sing for her father regardless. One day, she hears him say the word "war" and wonders why the room is burning. At the song's end, inside the wreckage of a house is the remains of a lonely man and a half burned doll. Although as she is not a human being, she survives. The "Lu Li La" lullaby is sung by the doll near the song's conclusion.

The song is directly related to the fourth song of the series, ハートビート・クロックタワー (Heartbeat Clocktower), and the fifth song of the Seven Deadly Sins series, 悪徳のジャッジメント (Akutoku no Judgement).

This song has entered the Hall of Fame.
