Idk what to call this anymore: (not demon slayer Todo/not a Todoroki chapter) Ei is Ciel. After the war between Celestia and the Abyss, they both agreed on peace and Kiana revealed that her sister and her husband traveled to different worlds for a honeymoon and soon gave birth to her niece and nephew, Aether and Lumine so they then made peace after finding out the truth and lived peacefully. The archons then became free from the strings Celestia placed on them to turn them into puppets and soon Teyvat was at peace from the abyss and the Fatui while Aether and Lumine settled in Teyvat as their home then Celestia suggested something to help Teyvat be a safe place for the people so they gave the archons a choice on who should leave Teyvat for a little while and find a way to get some materials over from other worlds back to Teyvat so the twins along with two archons will be sent out of Teyvat for the mission and Celestia just so happen to have a spaceship so they gave the archons control over the ship and they made their way to other planets and Celestia gave the two archons relics and magical objects and other items that would protect them during their travels but something went wrong. Alive Agni and Alois AU, alive Trancy servants AU, friends Ei and Kokomi AU, friends Ciel and Alois AU, archon siblings AU, the unknown gods name is Kiana AU, the unknown gods daughter is Paimon AU, reunited Aether and Lumine AU, Scaramouche reunited with his family AU, the Shogun's name is Hayami AU, the hydro archons name is Varuna AU, Our Ciel's real name is Astre AU.

No one's POV

In space, a ship from Teyvat was in the cold area malfunctioning terribly "Tsaritsa, we must head back to Teyvat with the materials we collected already" Ei said and Tsaritsa nodded "we can take the mini ships in the back to head back" Lumine said and the twins started to run to the back while Tsaritsa and Ei collected everything but something in the ship went wrong "Beelzebul? What are you doing?" Tsaritsa asked and the ship had flashing red lights "something is happening to the ship... TSARITSA GO NOW!" Ei yelled pushing Tsaritsa into the back on the ship which was used for emergencies "EI! WHAT ARE YOU DOING?!" Aether yelled and Ei smiled "the ship has something happening, Tsaritsa I gave you your gnosis... report back to Kiana while I go proceed with the mission" Ei said sending off the three and closed the ship and went back to the control room trying to fix it and the ship ended up sending Ei into another world where her ship crashed somewhere on the strange planet and she took her bag which can hold anything no matter how big or small it was. 

Ei then looked through her spell books and hide her and the ship and she left the ship, shrinking it and carried it in secret after taking one of the cloaks in her bag and traveled around the forest where she landed and found a cliff and an ocean was in front of her eyes shining as the rays of the sun hit the surface of the water "what is this place? It's beautiful... but it smells awful" Ei said sniffing the air and looked around and saw a large manor in the distance and used a spell to look closer to the manor and saw a pregnant women and her husband together and thought of an idea since the ship would take a long time to fix and she needs to learn more so she sent the ship to another place where she will find and buried her bag somewhere and used another spell and waited for the day where the women would give birth and make the women give birth to twin boys and Ei realized what she did and just accepted it. 

Years have passed and Ei or now Astre has been pretending to be a regular child but then it soon turned real as his memories has disappeared ever since he lost his gnosis one day and his magic became very unstable so he avoided using it and the mission lingers in his mind and comes up in dreams giving out signs but Astre completely forgets it overtime and one day when his family just went out and he had to be left behind due to his asthma, he met someone in the darkness of night.

"Who are you?" Astre asked and a person was at the end of his bed with a terrifying figure and the person turned into a harmless looking girl that was around the same age as Astre and she seemed sad "I'm sorry if I scared you... but is it possible that we can be friends?" The girl asked and Astre lowered his guard around her and crawled toward the girl with a smile and he reached his hand out "of course! I'm Astre Phantomhive, what's your name?" Astre asked and the girl seemed hesitant "promise to not be scared? Of the translation of my name?" The girl asked and Astre nodded "I'm Akumu, it means nightmare" Akumu said and Astre took her hand and shook it "it doesn't matter what your name means, I think it's beautiful" Astre said and Akumu just looked at him in disbelief and the two stayed up all night chatting and getting to know each other and Akumu showed Astre her dark magic that still needs some mastering.
