Satanael

( his human name and appearance do not matter)

Satanael is the character name for a certain player of yggdrasil who happened to be a member of the best Guild in the game Ainz ooal Gown. His character away was seraphim but unlike all other seraphim he had seven pairs of wings 14 in total it was all thanks to a skill that he possessed known as origin of sin and virtue half of his wings were white the other half were black. His white Wings represented the seven Heavenly virtue while the black Wings represented the seven deadly sins how I got that set skill was through the administration he was in fact a game tester that worked for many companies including the one who happened to own yggdrasil this offered him a number of various things such as skills, abilities, Magic, weapons, armor, even items, but most of which he was unable to actually use due to if he did without the proper setting otherwise he would be forcibly banned from the game how did you get this amazing job for various companies quite simple it's all he could do his body was dying very slowly of course and as it was working his way through a system began to shut off various parts of his body. Before he lost his hearing and sight he made a deal to be a human guinea pig and he would test out The limits of which they could push Consciousness into the virtual world so they put his body into a coma his mind could freely do whatever I wanted in the virtual world while his body they kept using various testing to a cure him and be to test various Technologies and medicines on the body to delay the illness

The skill origin of sin and virtue is a buff skill that not only increases the user but also those designated as bearers of either virtue or sin only one of each virtue and sin can be active on a person at a time up to 14 individuals. Each sin and virtue grants its own special effect that has its own merits and demerits I hope that's a good description for the skill

Seven deadly sins: Pride, lust, gluttony, Envy, Wrath, sloth, greed.

Seven Heavenly virtues: humility, patience , temperance, chastity, diligence ,charity, kindness. ( funny thing compared to the sins to virtues pretty much everybody agrees that the sins do not change however there are multiple different versions of the seven Heavenly virtues)

( he also made a number of additions to the tomb as well as made a number of NPCs)( also due to him not being able to use his body actual body and playing various games some [even adult game] in which he had used a female Avatar he is bi the only male so far as I know that he's going to sleep with is Mare unless I were to add other Femboy characters I'm also playing with the idea of just straight up genderbending them depends and how I feel) ( this is hopefully the final thing I am planning on expanding upon the new world beyond the anime as I haven't read the light novel like going to different continents or just countries outside of what is shown so might throw in some stuff from other things also I might even add some magical relics or items maybe even a spontaneously appearing gate [ you know the one] and finally a magical ritual site that could potentially go to other worlds not sure yet. Also I'm planning on using the game tester with a terminal illness as the base for most the different characters in this you can change it up to whatever gender you want and character race this goes for the game character as well)
