ハートビート・クロックタワー (Heartbeat Clocktower)

Background
Before his death the lonely man created a small theater deep in the forest "Heartbeat Clocktower" is the fourth song in the "Zenmai-Jikake no Komoriuta" series. The song was originally on Akuno-P's piapro page in 2009 and was exclusively for his fans following him on piapro. It was later included in his album "prelude to forest". Eventually, mothy made a "final" version of the song, with an added tag "(F.V.)" (Forest Version), uploaded to Niconico on April 26, 2010. It was initially released with his album "EVILS FOREST" but was released as a PV shortly after. It is also in the album Aku no Oukoku 〜Evils Kingdom〜.

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 a young girl "with ugly burns on her body" (The Clockworker's Doll) 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, and a "pretentious" servant girl (Waiter) who "indulges in selfishness", but expresses sadness for the loss of her "other half" (Irregular).

He also observes how the Kayo's Scissors and the Venom Sword continue to be "dormant". GEAR, realizing that the clock was going to stop soon, sacrificed himself to keep it running by taking out his own heart and using it to power the clocktower.

This song has entered the Hall of Fame.
