Heartbeat Clocktower

"On the verge of death, a lonely man create a small theatre at the back of the forest"  

Heartbeat Clocktower is a song released by Akuno-P on April 25, 2010. It is the fifth song in the Clockwork Lullaby Series, describing the experiences of GEAR in Evil's Theater.

Plot
The song concerns a mysterious clocktower and its actual guardian, GEAR. The dead owner, embodiment of Greed and former guardian of the clocktower, the "Collector," created a theater for the "Collectibles" where they forever enact their story. GEAR's main concern is to keep the Clockworker's Doll "with ugly burns on her body" alive through the clocktower, and if it stops, she will die.

Performing his task day by day, he describes other inhabitants of the clocktower, including the Master of the Graveyard, who devours any helpless visitor who had the bad luck to end up in the theater. A "pretentious" servant girl, who "indulges in selfishness," but secretly expresses sadness for the loss of her "other half".

He also observes how Kayo's Scissors and the Venom Sword continue to be "dormant". He also mentions that "when the entire songs are recited," it is believed that Utopia will be created. GEAR realizes that the clock is going to stop soon, which means that time is running out before the Clockworker's Doll dies. Without hesistation, GEAR takes out his heart, and sacrificed himself to power the clocktower. His sacrifice saved the Clockworker's Doll, but causes him to be part of the clocktower, unable to leave.

Handbeat Clocktower (EC 505)
Handbeat Clocktower's music is an arranged version of Heartbeat Clocktower and was used for promote the novel Praefatio of Blue. The song acts as the epilogue for the Story of Evil and reveals the conspiracy behind it.

Miniature Garden Girl (EC 983)
Miniature Garden Girl occurs 7 years before the events of Heartbeat Clocktower. The song details the life of the Clockworker's Doll before the incident in which she is severely burnt.

Master of the Court (EC ???)
Although Master of the Court hasn't a specified year, it can be inferred that it occurs after Heartbeat Clocktower and before Capriccio Farce. Because of GEAR's sacrifice, the Clockworker's Doll received the power of the Marlon Spoon, restoring her condition and transforming her into the Master of the Court, who continues the legacy of her father, seeking the Seven Deadly Sins.

Master of the Graveyard (EC ???)
Master of the Graveyard focuses on a particular Vessel that has become active in the recent years, and is mentioned by GEAR.

Capriccio Farce (EC 998)
During a trial held by Master of the Court, GEAR expressed his belief that, when all the vessels are gathered, there will be nothing left. But Master of the Graveyard taunts him by saying he is too powerless to do anything about it.

Conceptualization and Origin

 * The song's title references GEAR's sacrifice, where his heart is connected to the clocktower, letting his heartbeat power it and keep the Clockworker's Doll alive.

Curiosities

 * During the song PV, the Seven Deadly Sins are represented by gears colored with the respective sin's color, with each of the awakened vessls of sins' appearance being complimented with their gear turning in a corner of the PV.
 * During the titular sequence, the six gears representing the collected vessels of sin come together to form the songs logo, a grey gear; towards the end, a green gear representing the vessel of Wrath is seen falling on the edge of the screen, alluding to how it is the last vessel to be collected.
 * While GEAR sings about the doll's inevitable death with the clocktower broken, the teal gear representing the vessel of Sloth is seen spinning at a much slower pace then the gears for Vanity and Gluttony.
 * The song was rearranged by mothy to promote the The Daughter of Evil, Praefatio of Blue, titled "Handbeat Clocktower", a track sung by Kyle Marlon and included in Four Melodies of Evil, The Daughter of Evil Novel Music Collection as part of Story of Evil.
 * Interestingly, both songs maintain a grey gear in their song PV with Heartbeat Clocktower's gear turning blue, representing GEAR, and the final sillouette seen with the gear in Handbeat Clocktower being Kyle.
 * During the song's "Lu Li La" chorus, the images of the Seven Deadly Sinners followed by the Latin name for their respective sin appear translucent over Hänsel and Gretel; at the end of the sequence, the names of the four Masters' domains from End of the Four appear in the four corners of the song PV.
