Name: Satan Morningstar

Aliases: The Morningstar, the Demon, the Devil

Species: Demon (formerly an angel and then a fallen angel)

Occupation: Leader of the Demons of the Underworld

Abilities/skills: Satan has the power to lead people to their deaths, and she can do so in combat to a very high degree. She can make it so that the people she faces almost always die by her hand but some people can resist her power.

Satan can manipulate hellfire and she can do so to a dangerous degree such as making huge hellfire constructs, breathe out hellfire, and even make hellfire weapons if she loses her trident in action. Satan can even make an entire hellfire storm that can engulf the entire planet if she wanted to burn everyone and everything in hellfire.

Personality/appearance: Satan has a brash and impulsive behavior to herself even before she fell from heaven.

Satan has red eyes and long, red hair. As she is a demon, she naturally has pointy ears, two large curved horns on her head, and two black demonic wings on her back. Satan wears a black, sleeveless kimono with torn edges, red trimmings, and a burnt orange highlight along the bottom edges, as well as a sarashi across her chest. She keeps a white scarf tied around her neck, a purplish-brown scarf wrapped around her arms, and a red scarf tied to her waist. She has a short, red skirt and brown boots, with two black belts fastened around each of the latter. Satan wears knee-high socks with red bands near the top to secure them in place and she has two torn, black cloths around her wrists secured similarly.

When in combat Satan dons an obsidian knight-like armor that covers her entire body from head to toe. It is made out of Argentium, a metal forged out of the souls of the damned, and this armor is capable of enduring the hottest temperatures such as the temperature of the sun.

Possessions: Satan possesses a red trident named Lucifer's Inferno, and it is capable of causing people to catch on fire with hellfire whenever it touches or hits someone. The demon can even use the trident to shoot out hellfire or even cover the entire thing with hellfire. Her weapon is also made out of the material known as Mordite and it can kill mortals instantly simply by being stabbed by it. However, stronger beings would last longer before finally succumbing to its instant kill effects.

Backstory: Satan was created by God along with the other angels before going on to create humanity. However, Satan grew a bit jealous of her sister Michel who ended up becoming the commander of Heaven as well as get the attention of God. She ended up causing a rebellion, due to the influence of Backbeard, along with her followers, and tried to take over heaven due to jealousy.

However, Satan and her followers were banished by God along with Michel down to Earth. The now fallen Angel and her followers then made their home in the Underworld. Satan eventually became a demon and most of her followers did as well, but some remained as fallen angels. The now demon also coexisted with the new leader of the fallen angels, Azazel, in the Underworld.

Some centuries after being banished, Satan ended up regretting her actions of rebelling against God and wanted to seek forgiveness. However, she was imprisoned by a group of demon rebels known as the Old Satan Faction, who wanted to take over the world and overthrow heaven and also take it over. Satan was imprisoned in her cell but was freed from her prison by none other than Iesua Nazarenus, who actually was sent there by God to forgive Satan of her sin. While she was in prison, the Old Satan Faction was destroyed by the Absolute Dragon God, Ryūjin, after he found out by God that they were the ones that made his brother Trihexa go on a rampage and also attempted to mind control him. After being forgiven by Iesua, the demon ended up making peace with God along with her faction in the Underworld. Azazel too also made peace with Heaven as well after Satan did so as well through the formation of the Heaven Treaty.

After making peace with God, Satan can now come to Heaven and visit her Creator whenever she wants. It is also during this time that Satan ended up making up with Michel and became sisters despite Satan being a demon.

Satan, Azazel, God, Iesua, ZUN, and the Four Archangels of Heaven watched the Dragon Incident in Heaven.

After the Dragon Incident, Satan would then become one of the three judges judging the competitors of the First Gensokyo Tournament.

Relationships:

God: Satan sees God as her Father/Creator as she was created by him. Satan originally hated God for banishing her from Heaven but realized that she was wrong the entire time and ended up making up with God after Iesua forgave her.

Azazel: Satan is friendly with Azazel even before the formation of the peace treaty as he doesn't do any conflicts between the fallen angels and demons of the Underworld. As a result, the two leaders of their own respective factions coexisted and even more so after the formation of the Heaven Treaty.

Trihexa: Satan is actually in love with Trihexa and was sad to see him be sealed up. Though Satan ended up confessing her love to Trihexa after he was freed from his seal by Misaki Hakurei. Nowadays Trihexa and Satan are a couple together.

Ryūjin Ryu: Satan is friends with Ryūjin and is also the sister-in-law to him after being married to Trihexa. Though she was a little disappointed that he wiped out the Old Satan Faction before she could, but she quickly forgave him as she understood his vengeful actions.

The Demons of the Underworld: Satan cares deeply for her followers/subjects of the Underworld and as a result, they have respect for the demon.

XXXXXXXXXX

Name: Iesua Nazarenus

Aliases: Daughter of God, Queen of the Jews, the Saint, the Messiah, Savior of Mankind

Species: Saint

Occupation: Ruling (Bible) Heaven Along with her Father

Abilities/skills: Iesua possesses many powers to which humans will consider as miracles. She can cure people of diseases that would seem incurable, turn water into wine at the Wedding of Cana, and was able to come back to life after being dead for seemingly three days. All of these were done due to Iesua simply being the Daughter of God and the one to free humans of Original Sin so they can come up to Heaven.

Iesua is also capable of using holy powers as well in combat. She of course can also form holy crosses and bullets as well if she faced off against an opponent.

Personality/appearance: Iesua as depicted in the Bible is known for being a very kind, gentle, and outgoing person. While she is known for being a pacifist that doesn't mean she won't defend herself and (mainly) others from harm, and of course fight people if the time comes, not that she likes it for she greatly dislikes resorting to violent actions.

Iesua has red eyes and short, bluish-gray hair. She wears a dark green headband with pointed decorations, along with having a flower on it. Iesua wears a white, long-sleeved shirt as well as a four-layered, white and blue ankle-length skirt, each containing dark green trimmings. She has a cyan bow and a red cloak attached to her neck, the latter of which she normally holds closed with her left hand, as well as black shoes with gray socks that go up to at least her knees. Iesua wears bandages over her hands, forehead, and right eye, which cover the same wounds she gained before she died. It is hard to tell, but underneath her clothes are even more bandages wrapped all over her body.

Possessions: Iesua has the same cross that she was crucified on and was made into a weapon for her to use by her father. It is made entirely of holy wood meaning it would kill any demon or demonic entities if touched by it.

Backstory: Iesua herself was present to see the creation of Mankind by her Father and their eventual banishment from the Garden of Eden. Iesua was then incarnated into the world of Earth and became a human but with the Holy Powers of God. In essence, she is fully human and fully divine at the same time. She was incarnated to be the daughter of Mary of Nazareth and Joseph.

Iesua during her life helped many people and also had disciples as well. However, Iesua was then betrayed by one of her disciples, Judas of Iscariot, and sold her out to the Roman authorities of the Roman Empire, who were pawns of Backbeard at the time.

Iesua was then crucified on the cross by the Roman Soldiers, and eventually, she died there. She didn't at all retaliate with her divine powers as she wanted to save mankind from Original Sin committed by the first humans Adam and Eve. In essence, Iesua's death was planned by the Father and Iesua herself to open up the path of salvation for all of mankind. Iesua was resurrected three days after her death and had her disciples, now called the Apostles, proclaim the Good News of God and the Gospel.

Iesua would then be sent to the Underworld and free Satan Morningstar after being imprisoned by the Old Satan Faction. When asked by the demon, she was sent by God to forgive her of her sins. Satan accepted as she came to regret rebelling against God centuries ago.

As a result of forgiving Satan, Iesua was able to make true peace with the demons and the fallen angels of the Underworld. The Daughter of God was also present to see the peace treaty be created making peace with the fallen angels and demons of the Underworld along with the angels of Heaven.

God, Holy Spirit, Iesua, Azazel, Satan, the Archangels of Heaven, and ZUN watched the events of the Dragon Incident unfold from Heaven. Iesua also went to see the Tournament of Gensokyo hosted by the Absolute Dragon God, Ryūjin.

Relationships:

God: Iesua, God, and the Holy Spirit have existed before the creation of Mankind. Yet Iesua sees God as her Father, which he is in a sense. God also cares deeply and loves Iesua as his child just like everyone else in Heaven.

Holy Spirit: The Holy Spirit guided Iesua while she was still alive on her mission to have mankind be given salvation through her sacrifice. Even after becoming a saint after being resurrected, Iesua is still guided by the Holy Spirit and the entity helps the Saint when the time comes.

Satan Morningstar: Satan was forgiven by Iesua which of course led to Satan becoming friends with the Saint. The two are very well known as Satan and Iesua come to visit each other in the Underworld or in Heaven.

Mary of Nazareth & Joseph: Iesua still sees Mary and Joseph as her two parents even after she was reunited with her true father in Heaven. Mary and Joseph still love Iesua as their own child as well.

The Residents of Heaven: All of the Residents of Heaven have love, adoration, and respect for Iesua just as they do with God. Iesua also loves all of them as well just like her father does with them.

Theme Song:

東方邪星章 ~ The Last Comer OST - Iesua Nazarenus's Theme

A/n: Satan Morningstar has the exact same appearance and apparel like Mumumu Mikaboshi from the Last Comer, but the difference is her name, some slight changes to her appearance, her backstory, and of course her abilities. Iesua herself still looks the exact same from the Last Comer, but like Satan has more powers and a backstory that coincides with the story of Jesus Christ in the Bible.

Also I myself like the Last Comer and I do like the game as it makes pretty cool references to Christianity (I myself am I a Christian) and I decided to have some of the Christian touches be added to each of their backstories.
