The series focuses on the "Cardinal Sins", the vices used since ancient Christian times in order to instruct on the morality of humanity. While more minor sins, "venial sins", could be easily forgiven through sacraments, the cardinal sins would lead one to eternal damnation if not absolved through Penance or perfect contrition.
The theme is common in Catholic tradition. The definitions have changed throughout the years, but there is a general agreement on the current seven with their current Latin names.
Due to the events of the Original Sin series, the Seven Deadly Sins were spread around the world therefore tainting it. After their creation, the Sins have been changing their shape and owners, being eventually stored in different objects denominated the Vessel of Sins. Different persons, groups or organizations during that history tried to recollect them, each one with their own personal goal or intention.

About the song The Tailor of Enbizaka:
The songs sequel; "The Weathered Head at Onigashima" reveals the tailor's execution, at the hands of a young boy.
About the song The Lunacy of Duke Venomania:
This song has been confirmed to come directly after Chrono Story in mothy's chronology and the Venomania mansion is shown at the end of the Chrono Story PV.
In the PV, during the musical intermissions, appear some missing people posters with parody names of the female VOCALOIDs UTAUs and Fan-made VOCALOIDs, along their age and current occupation. These ones are:
The newly released PV divides the song in Chapters, each one with their respective title. The names of those ones are:
The Corrupt Judge and His Sullied Court.
The Girl of the Miniature Garden and The Vessel of the Sin.
The Beginning of a Civil War and the End of His Judgment.
Master of the Hellish Yard and the Final Judgment.
Also, the number of the fourth chapter is written with the kanji for "death" instead of "four" (both have the same reading in Japanese, and the number 4 is often associated with death).
The PV for this song also implies that GUMI is the "Master of the Hellish Yard". This may be a reference to the fact that Satan is the Patron Demon of the sin of Wrath, which is set to be represented by GUMI. Satan is often portrayed as the ruler of Hell (i.e "Master of the Hellish Yard").
In the PV, where Gallerian is 'falling into the bottom of hell' through a blue tunnel, you can see 5 colored circles in the tunnel wall. The colors are in this order: purple, red, yellow, teal, and pink. It represents the order of the other 5 deadly sins in the series, with Lust (purple) occurring first and Envy (pink) occurring last.
Gallerian's name comes from the word "Galleria" (Italian word for "Gallery").
In most of the songs (exceptions are "Gift from the Princess who Brought Sleep" and "Tailor of Enbizaka"), KAITO's name features the name "Marlon."
