Since a friend of mine was annoying the shit out of me to tell him the general gist of the story I came up with this shitty summary: (just keep in mind my Japanese is nowhere near an acceptable reading level as of yet I'm not even at FULL N1 level.)
- You wake up in a human village with no recollection of your memories except you're supposed to be an angel soldier, you save Rebecca and she tells you a group of angels called Egrigori descended to earth and began massacring everything, she joins you since her family is dead and she's also an alchemist.
- At the Museum you have a meeting with you-know-who, she subtle mentions she didn't know you were still alive, you ask if she knows who you are and she replies, she won't tell you because of your dark powers, she calls you a depraved big titty angel and fights you.
- At the Cave of Rituals, you meet up with Raphael and almost start a fight after which he tells you he/she is your superior and you're supposedly one of his BEST soldiers, he tells the gate to Hell is sealed and ask you to find another way, he will go back to Heaven since he can't stand being in the "contaminated" Fallen Earth since it stinks, you wonder if it would be best to tell him about Rebecca but chooses not to, you also ask about your dark powers and is told not to overuse it. At the gate Rebecca says she will have to go to the other side since the seal might be there, at the other side Rebecca uses her alchemy and opens the gate to you.
- At the Astral Shredder you meet up with you-know-who now dubbed as Black Winged Angel, she presents herself as Sariel the Leader of the Egrigori and asks if Selenia would like to join her saying Selenia could entice men with her big boobs, she finds Heaven to be very boring and she tells you she doesn't particularly love nor hate the humans but she's enamored with all the bad stuff that make us humans good (depravity and etc...)
You reject her and she recalls she has been rejected once before and then you guys fight.
- At the Corrupted Garden you meet Raphael once more, now he/she is kind of pissed of since it's taking too long to get rid of Sariel and he wants to get the job done asap so Michael would shower him/her in praises, he/she also notices a faintly smell of human in you.
At the end you end up meeting Sariel and she explains what will happen in the near future, Raphael plans to wipe out the entire earth in a great flood that's why Her Egrigori and her were fighting against Raphael's subordinates, amidst them was a stubborn and big titted angel, she tried to recruit her but since she refused Sariel instead depraved her of her virginity with her staff that's when the angel fell off to earth, IT WAS SELENIA. Once again she asks if you would like to join her and protect the now Fallen Earth from Raphael's plans. You Refuse once again and she gets mad because you remind her of another girl (Angelica from Depravia 1.)
After which you kick her ass.
Endings:
D - You beat Sariel, Raphael shows up and congratulates you for a job well done and is happy that now Michael will give him/her lots of praises, Rebecca shows up since the demons have vanished after you fight with Sariel and Raphael is absolutely mad, it scolds you for mingling with lowly humans and notices Rebecca is pregnant with a demon inside her and tells you to kill her, Selenia is hesitant but it's too late since you have been using your dark powers a lot Rebecca's gestation accelerated and the demon is brought out to life, you put Rebecca out of her misery, go back to Arcadia where you're promoted to Dominion rank but Selenia is utterly depressed, she tells she would do whatever it takes to see Rebecca's smile again.
C - Same thing, but now you haven't over used it your dark powers so you end up opposing Raphael, you guys fight and apparently you win that's when Raphael comes from above you, YOU FOUGHT A CLONE/AFTERIMAGE. He takes you and Rebecca and trial you guys, Rebecca is raped by angels to purify the demon inside her.
B - You kick Sariel and Raphael's butt, since you guys opposed Raphael, Selenia says you two might end up being hunted after which you go after a way to cure Rebecca's, apparently you stumble upon some documents at the Museum (stage 2) about a Holy Water spring that can help them, you go the spring and there Rebecca wonders what will happen, she says it will be a little depressing if her child simply disappears instead of being purified but Selenia tells her to not worry about it.
A - After you weaken Raphael, Sariel comes in and absorbs he/she and tells she's going after the other Archangels, you arrive at Arcadia to witness Sariel's Egrigori are raiding the shit up, there's not much here aside for asking you to join her again and that she's after Michael and Angelica for the past 1000 years, you beat Sariel and Michael commends you for dealing with both Sariel and Raphael, Michael apologize's for not noticing Raphael's plans to flood the earth and makes a remark she has gone too soft, you report about two matters you have been worrying over, 1st your dark powers and then 2nd Rebecca's pregnancy, Michael says that know that Sariel has been dealt with your dark powers should dissipate and tells you take Rebecca to the Holy Water hot spring at the human world to purify her pregnancy and not to worry she will give birth to a normal child. Michael also remarks Selenia made her remember of that other girl (ANGELICA AGAIN.)
S - Same as A with Sariel bonus scene, she's already cooking up her 3rd coming, now she's raping Raphael in order to give birth to something very fearsome and not even Selenia, Michael or Angelica knows.
That's about the gist of everything, if anyone can give better insight please do.
