Story idea's up for adoption [prompts]

Okay so I've had this idea bumping around my brain for a while and it won't leave so I offer it here in the hopes someone will write it.

Inuyasha canon is changed up where Kagome has given up on Inuyasha. He's still her friend but she does not love him romantically. Koga, along with Ginta and Hakaku, are invited to join the gang as they hunt Naraku near the end of canon.

Kagome falls for Koga but they don't get a chance to get together before the canon ending happens. Kagome is in the present and finishes school, writing her experiences down in her diary, and spending time with her family. When she jumps through the well again things change.

By jumping through the well she ends up in the future a few years before the story of Overlord starts. Her brother Sota is either an Extremely old man or has passed on, either way he decided to put her in his Will in case she went the wrong way through time. He also used her diary to make money via "tragic fantasy romance".

Kagome cannot go back to her time, much less the feudal era, and so much adapt to this world. She is more mature but also slipping into depression because she just lost everyone in the blink of an eye.

She uses the game Yggdrasil to cope.

She ends up choosing a heteromorph race, I can easily see her has choosing angel but it's up to you, and befriends Momonga and the rest of Ainz ool gown.

Her character looks very close to herself just with nicer outfits, weapons, stuff. Her backstory is her real backstory, including her lost love, but most of the guild think she's role-playing.

She has only told Momonga and the creator of Demiurge that her backstory is true (or at least implies that she connected to the story because of how close it was to her own). She stays in the guild and even stays with Momonga when the server is shut down.

It isn't until after they're transported that she tells Momonga the full truth. Momonga has no idea how to handle that but she is his best friend (whom he sees as a sort of sister) and he wants to help her through her pain.

The npc's love the both of them. There is no jealousy towards her relationship with Momonga because the npcs remember hearing him tell the other guild members that she is his sister/like a sister.

Overlord canon goes on with the both of them trying to figure things out.

Perhaps the new world is connected to more worlds than just their old one but because Kagome is there things are changing. Her Miko powers have made a resurgence dispite her change in race, she can sense something but not specify what or where.

Perhaps some npc's read her backstory from behind the other guild members who read it, perhaps they overheard them talking to her about it, either way some of them decide that along with conquering the world they should find a way to open a door to the world her lost ones exist in.

She does not know their plans.

She is known as being kind to all of them but also sad, she has moments of melancholy, moments where she will disassociate, ect.

[If she is of the angel race. Demiurge's creator will, after finding out her backstory is close to true, put in Demiurge's code not only loyalty to the guild but that...dispite him being a demon he will see Kagome in a good light/not turn on her/not hurt her/will help her through her pain. Role-play reasons]

At some point something changes, a familiar face shows up. It seems there is a way to the new world from the feudal era and the yokai are coming through to escape the growing human problem. [Or a door was opened by the NPC's and the yokai are taking the opportunity to fins a better home, either way]

Kagome is shocked to see Sesshomaru there along with a tearful Shippo. Her human friends have passed on at their point in time, Inuyasha's location is unknown, and more yokai are coming.

Ainz welcomes them all to stay and the npc's get along rather well with the refugees.

It is a tearful, and smoochy, reunion when Koga, his tribe, and their wolves arrive.

Feel free to change up things as long as the pairing is the same (or Kagome x Sesshomaru, but we need more Koga to be honest).

Have fun writing!
