Seven Deadly Sins

The Seven Deadly Sins (七つの大罪 Nanatsu no Daizai) series is a series of songs made by mothy, also known as Akuno-P. The series is composed by seven songs, with 6 of them released

Most of these songs were featured into the album 悪ノ王国 ～Evils Kingdom～ which was released on December 22, 2010.

Background
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.

Plot
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.

The series focus in 7 songs, 7 moments in The Evillious Chronicles when the Seven Deadly Sins reached their climax, causing massive suffering and death.

Identifying the Songs
There has been confusion in the past as to what songs are the seven sins. This is simple, the songs share a group of characteristics that identify a Seven Deadly Sin song. Those are: Any song that does not meet the above requirements is not a Seven Deadly Sins song. Last Revolver, while it is a good song, is not part of this series. Neither is Heartbeat Clocktower nor Miniature Garden Girl. moonlit bear is not a Seven Deadly Sin song, nor is Madame Merry-go-round.

 * Example: "Saa, Nemurinasai..." or "Now, go to sleep..." (from Acedia)
 * Their sin is portrayed in some way
 * In the end, they are killed or die as a direct consequence of their sin

Novel
After the success of The Daughter of Evil novel series, mothy announced on his blog the release of a news novel series dubbed as Seven Deadly Sins of Evil (悪ノ大罪), which will deepen the story behind each song.

Lu li la, Lu li la, the Resounding Song
Sung by Kagamine Rin and Len Append This song vaguely speaks of the items that each sin has, and how those ones changed from their form shown in Chrono Story to the one depicted in the the cover art of Evils Kingdom's Album. It also gives the general order in which things happen. At the end it says "They all return to the forest, with an uncontainable amount of anger," possibly referring to Wrath.

 * About the song Gift from the Princess who Brought Sleep:
 * At the beginning of the PV the English definition for "GIFT" is shown. Just before revealing the homicidal rampage caused by Margarita, the PV reveals that "GIFT" in German translates to "POISON".
 * In the PV it gives several cut-off quotes telling the story in more detail. It mentions the Freesis foundation. The quotes are as follows:
 * Marquis Blankenheim, passed away.
 * Doctor Felix, in critical condition.
 * 24 dead in the hospital, cause unknown.
 * Toragay is plunged into panic by the mysterious sickness.
 * Behind the scene is the criminal organization Pere Noel [unknown cut-off word]?
 * Will the Elphegort government entrust the investigation to the Freesis house?
 * The traffic between the capital Aceid and Toragay is now cut off.
 * The Freesis Foundation and its investigation team head out for Toragay.
 * Toragay is already in a state of ruins.
 * About the song Judgment of Corruption:
 * Apparently Gallerian Marlon himself lives in Levianta
 * Gallerian Marlon is the descendant of Kyle Marlon (from Daughter of Evil).
 * 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 number 4 is often assosiated 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 generally portrayed as the ruler of Hell (i.e "Master of the Hellish Yard").
 * If the Master of the Hellish Yard is Satan, the Master of the Heavenly Yard would be God.
 * 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) occuring first and Envy (pink) occuring last.
 * Gallerian's name comes from the word "Galleria" (Italian word for "Gallery").
 * In Chrono Story, the fragments of the Seven Deadly Sins are represented by the colors of the Vocaloids who portray them (purple for Lust, red for Gluttony, yellow for Pride, etc.) but curiously Wrath is represented with the color white. However, in the newly released PV for Judgement of Corruption they change this and Wrath is represented with GUMI's green color.
 * The reason why Wrath is represented as white is due to Clarith (Haku) was fated to be the Sinner of Wrath. However because this was prevented at the end of Daughter of White, the event was postponed and the fated one passed to a GUMI's character.
