Irregular is the mysterious entity that dwells inside the womb of the Master of the Court. It's hinted that after his rebirth, he assumes the role of the Master of the Heavenly Yard.

Awakening
Irregular awoke in red and blue chains in a dark room painted black. 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. It said. 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.

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."

Allen Avadonia: Irregular and Allen bear an obvious connection.

Conceptualization and Origin

 * Irregular parallels Jesus Christ. He was "conceived" in the Master of the Court's womb without a father, and it is hinted that he will be reborn as more powerful being: the Master of the Heavenly Yard.
 * 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

 * The Master of the Heavenly Yard's posture 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 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.
