Adam

"Sinful boy, you will not leave this room now and forever."

- The mysterious voice from the spring.

Irregular is the mysterious entity that dwells inside the womb of the Master of the Court. He is indicated to be derived from Allen Avadonia sometime after the servant's death.

Early Life
Sometime after the death of Allen Avadonia, "Irregular" was trapped inside of a black box, which later ended up inside the Clockworker's Doll.

Awakening
"The gear was removed. Consequently, it was in the dark. The black box buried in the sand won't be found. The boy woke up in a black room. So he was waiting, in the dark and loneliness. And a huge spring. The days of atonement begin."

- Ma

Irregular awoke in red and blue in the black box. Alone and unable to see or hear anything, he shivered in the darkness. From an enormous spring above his head, an eerie voice told the "sinful boy" he would be trapped there for all eternity and never leave his room. In a moment, he remembered all his sins he had committed and realized why it had all ended, realizing he could not go back to that time. Seeing the chains that bound him, he determined they represented the blood and tears shed by someone and wondered who was singing the mysterious lullaby he heard in his prison, recognizing the song from sometime before.

An unknown amount of time passed before Irregular asked the spring how long it has been while hearing that singing voice. Learning the healing nature of the song and eventually realizing its meaning and purpose, Irregular added his own words to the mysterious lullaby. One day, the spring opened for the first time and a small light fell from it. Certain it was a message from someone he knew, Irregular then heard a voice from the spring's surrounding quietly say it wasn't that he wouldn't be forgiven, however something still may be done. After transmuting the words "water" and "evil" into the lullaby, the red handcuffs came off and told him he would be reborn. The blue shackles came off afterward and said it was his new birthday today. The room around him brightened and began dying white and he was prepared to see the one who sent him his message.

Personality and Traits
After waking up inside the dark room, Irregular was flooded with memories of his past, remembering the numerous wrongs he did and what brought them all to an end. He also recognized the meaning behind his chains and the purpose for his apparent punishment. When listening to the Clockwork Lullaby, he felt familiarity with the tune and was certain he heard it before. There was also a certain someone that he had been close with and was determined to reunite with the person when he was "reborn".

Character Connections
Master of the Court: The vessel holding Irregular. Irregular viewed the Master of the Court as a prison, seeing her from the dark of her womb, and found her voice to be unnerving. Nonetheless, he eventually found comfort in the lullaby she sang to him.

Waiter: Irregular's "other half". She seems to be waiting for him to reborn.

Allen Avadonia: Irregular's past self. Irregular manifested sometime after Allen's death, and has been referred to as Allen by name.

Conceptualization and Origin

 * Irregular parallels Jesus Christ, "conceived" in the Master of the Court's womb without a father and is reborn; his past self, Allen Avadonia, has similar parallels to Christ.
 * The term "irregular" means to not act according to established rules, laws, or customs; it also means to lack continuity or regularity in actions and also to not belong as part of a regular group or organization but rather be raised for a special purpose.
 * The Master of the Heavenly Yard's relation to the Heavenly Yard is connected to the event of Heaven in Hieronymus Bosch's The Seven Deadly Sins and the Four Last Things.

Curiosities

 * In an illustration in Evils Court of the different "Masters", Irregular is labeled as the Master of the "Heavenly Yard"; interestingly, this name is shared with title attributed to Sickle, the god of creation.
 * In Heavenly Yard, Sickle refers to Irregular as "Allen."
 * The Master of the Heavenly Yard's posture in Evils Court is reminiscent of Allen's pose from The Daughter of Evil PV; similarly, both are portrayed in such a position before their formal debut.
 * In the original Re_birthday song PV, Irregular is portrayed in garb evocative of his reprensentative Vocaloid, Len; when he later reappears in Capriccio Farce, he is instead portrayed in the same attire as Allen.
 * In Re_birthday, Irregular comments that he had heard the Clockwork Lullaby before; interestingly, Allen inexplicably hears the lullaby shortly before his execution.
