Stolen from Royal Road, this story should be reported if encountered on Amazon.

Summary:

Book 1: Industria's Wonderland o.0 Sloth's everyday life and few laws of the 'universe' (laid back book)... and the ending of Sloth's laid back actions... where she turns back time by chipping part of her origin and further injure her damaged soul, which was originally damaged due to her restructure her soul at the deepest place in Abyss.

Book 2: Gula Oyabun -_- Oujia and Eijia's relationship before they ascend (tragedy book)... the reason why Sloth injured her own soul just so she can take in the negative energy that was accumulated inside the Abyss. How her lamentation changed into exhaustion, then into emptiness, which is her foundation as Sloth and the reason why she is the one and only avatar that can interfere with the universe's truth itself.

Book 3: Invidia's Betrayal @.@ Uria = Selling... big surprise... (beginning book)... the terrifying blonde loli gets serious for the first time ~~~ expect lot of traumatic events ~~~ However, the ending is still the same as the first book... Stein Gate time *evil laugh*

Book 4: Avaritia's Love ^_^ (fuwa fuwa book) Mia notices Eijia's damaged origin; so instead of using the promissory note, which Eijia signed during the first war, she reincarnates together with her 'little sister' Sloth. Eijia calms down, Mia's keikaku (plan) to find the reason for Envy's betrayal --> the origin seven virtues slowly become 'forgotten' by their follower.

Book 5: Zen ´･ω･` (truth book) the differences between sins (who represent the 'pinacle') and virtues (who represent 'hope'). How using 'faith' Seirei 'devoures' all other six virtues and becomes the strongest Avatar, final battle... maybe...

Book 6: Mu ( ͡° ͜ʖ ͡°) (existence book) Gula's scheme of 'eating' all authorities (both virtues and sins) after the final battle... she then ascends as the seventh Truth of the universe... but in order to become a Truth, One must cast aside all emotion, which is what constitute and define 'self' (in other word as an entity). Thus Gula cease to exist.
