The series is set in Bolganio, a fictional continent in the series' world, with most of its major actions taking place in its western region, Evillious. The main storyline occurs around the northern area of the region. Originally, the series begins in the "BT" era, but after the birth of Hänsel and Gretel, the Evillious Calendar is established and "EC" is used for events up through EC 015. Because of the prophecy made by Queen Alice Merry-Go-Round, Leviantan politics play a large role in the events taking place.
Magic Kingdom LeviantaEdit
A large and powerful nation in the northern area of the Evillious region. Becoming one of the most magically and technologically advanced nation of its time, Levianta rivaled the Tasan Empire. Its people worship the twin dragon gods, Levia-Behemo. At the time, the country is being terrorized by the criminal organization, Apocalypse. However, Maria Moonlit's prophecy changed everything.
Kingdom of ElphegortEdit
A peaceful nation south of Levianta. Originally known as Heldogort, the country split off its religious ties to the Magic Kingdom in favor of worshiping the dragon god Held, the Magic Kingdom branded its followers as a heretic cult and suffered repression from its neighbor. It is said that the forest in the southern area of the country is inhabited by Held, believed to have incarnated as a tree.
The composite entity born in Eve Moonlit after stealing the infants Hänsel and Gretel and subsequently killing their mother, Meta Salmhofer. After Eve's death, her foster children then split the Original Sin in her remains into seven fragments, using them to create the vessels of sin before scattering them across the world.
An artificial human created via scientific experimentation. They were created by Seth Twiright for the purpose of increasing the number of HERs in the world. They tend to suffer a harsh social stigma for their existence and live difficult lives. The process of creating a ghoul children was presumably lost followng the Levianta Catastrophe.
A forbidden ark in Levianta, containing the twin gods Levia-Behemo. It was brought into the Third Period from the previous world. Maria Moonlit prophesied that it would bring destruction to the Magic Kingdom, leading to the creation of Project 'Ma'. The machine was later used by Kiril to revive Elluka Chirclatia, causing it to create a huge explosion; it was ultimately buried due to the resulting catastrophe.
Seed of GodEdit
An element of the birthing process for Project 'Ma'. It is assumed to be the fertilizer for the selected candidate's egg to conceive the twin gods. It was injected into the recipient mother to conceive the twins. During Seth Twiright's tenure with the project, the seed was secretly replaced with a Seed of Malice.
When the series was first conceptualized, it was told in reverse order, with mothy releasing Tale of Abandonment on a Moonlit Night first, followed by Moonlit Bear. He later uploaded the Clockwork Lullaby song Chrono Story to bridge the Original Sin Story to his Seven Deadly Sins Series. Since the release of Original Sin Story -Act 1-, the songs' story has been retold in a more linear manner while being divided into several "acts". Although not reaching the same popularity as some of his other series, the series has become an important backstory for mothy's Evillious series. Akuno-P has released a "complete edition" compiling all the previous and new songs in the series.

Conceptualization and OriginEdit
- The series is partially inspired by the Brothers Grimm's tale Hänsel & Gretel and the biblical Book of Genesis, particularly the Original Sin and the Fall of Man.
- Each dedicated album's division into "acts" reflects a multi-act structure used in plays, movies, and other forms of media.
