Lost Souls

You suddenly fell to your knees. Your wounds had healed, so what made you fall? Then you saw a vision.

"I promise you! In another life, your sister and I won't let you die! We'll do whatever it takes!" you heard someone yell. He was holding a girl that looked exactly like you. Another girl was crying next to him holding the girl who looked like you's hand. "I promise you sister!" he yelled again. He then buried your body and he and the other girl sobbed even harder.

"(Y/N)!" Shinobu yelled. "Are you okay?" Kanae asked. "I- i'm fine." you replied. "Who was that?" you thought. "Come on, let's not be late." Kanae said. The five of you walked off.

"Giyu did what?!?" The Master exclaimed. "Isn't (Y/N) married?" You blushed once again. "N-no Master, dating." "Ara Ara~ Not a bad idea~" Doma exclaimed. "No, Doma." you explained once again. "Fine..." he whined. "What Giyu did was completely unacceptable. I will have him banished from the Demon Slayer corps and he will never lay a finger on you ever again (Y/N)." The Master explained. "Thank you Master" you and Doma thanked. Rui tugged at your uniform. "Mama, I'm tired. I wanna go back home." "We will, but Mama has to do some work first." you explained. Doma picked Rui up and headed back home. "Doma!" you called. "Make sure to feed him! He hasn't eaten!" "Will do love!" he called back. "Let's get back to work, Master."

Time Skip
"That mission was unbelievably long." you thought to yourself. "Doma's gonna kill me." As you sighed you crossed paths with Sanemi, the Wind Pillar. "Hey, Sanemi!" you waved. "Tch" he scoffed. "Going on a mission?" you asked. You still wanted to spark a conversation. "Yeah, Kanae's coming with me so I'm going to see if she's ready." he explained. "Um, do you know if Kanae loves anyone?" he asked nervously. "Not that I know about. I've seen her journal though and she always talks about one of the pillars. He's got hair like yours." you explained. "Is that so?" he mumbled. "Hmm? Did you say something?" you asked. "Oh no! Thank you... (Y/N)" he said. "I think someone's been shot by cupid." you thought to yourself as you shook your head and looked at him.

As you approached your estate, you saw Doma trying to comfort Rui, who was crying. You ran up to Rui and swept him up. "Hey baby! What's wrong!?" you exclaimed. "Mommy! I didn't know where you were!" he sobbed. "Yes, where were you love?" Doma asked tapping his foot. "My mission took a little longer than usual." you explained. "Oh by the way, you had some visitors Mama!" Rui exclaimed. "Hi (Y/N)-san!" It was Tanjiro! "Tanjiro-san! It's been so long!" you exclaimed. You ran up and hugged him. "How is Nezuko?" you asked. "She's amazing! She can now legally fight demons with me!" he answered. "That's amazing!"

As the two of you continued to catch up, Doma began to look more and more pissed. "Doma-kun? Are you okay?" you asked. "Mhm! Totally fine (Y/N)-chan!" Doma said. You knew deep down that he was really trying not to kill Tanjiro in front of Rui. "Hey Rui! Do you want to go inside?" Doma asked. "I wanna stay with Mama!" Rui whined. "Okay..." Doma muttered. "I have to go find Inosuke and Zenitsu..." Tanjiro started "I'll see you soon!" "Bye Tanjiro!" you called. Doma swept you off the ground as soon as Tanjiro left. You couldn't fight back because you were still holding Rui. "Doma!" you yelled. "Daddy!" Rui called.  "He then stopped in the bedroom and froze. "Why exactly are we here?" you asked. "Honestly, I don't know. -_-" Doma replied. "I'm gonna go to bed.. but before I do..." you looked at Rui. "I have a surprise for you~" "What is it?" Rui asked with sparkling eyes. 

You walked down the hallways of the mansion and stopped at a certain door. The door had webs all over it. "Woah!!!!" Rui yelled. "Go on in!" you told him. Rui slowly opened the door and saw a room covered with webs. "This... is my room!?!?" Rui exclaimed. "Yup! I had Kakashi decorate it!" you answered. He came and hugged you. "Thank you Mama!" "You welcome Rui!" you replied.

You went back to you and Doma's room and saw Doma crossing his arms and tapping his foot. "Doma-kun? What's wrong?" you asked. "Rui keeps stealing you away from me!" Doma yelled. "Doma! We literally adopted him!" you yelled back. "I'm your boyfriend! I may as well be your husband by now!" Doma argued. "Doma, sweetie, that's not how it works." you calmly responded. "Y'know, because Rui's been stealing you from me- "Not stealing Doma. He's 5." "Taking your attention from me, I haven't been able to kiss you." Doma corrected. You blushed red. "W-what?" "You heard me love. I haven't been able to kiss you." Doma said, getting impatient. You walked up to him and gave him a quick peck on the lips. "I think you misunderstood (Y/N)-chan. I want you to kiss me or I want to kiss you." Doma explained. "Doma are we really doing this right now?" you asked, embarrassed. "Well, you need to do it correctly. Do you need a demonstration? Never mind, I'll just do it for you." Doma said. He went over to you and...
{No Details}
You woke up to find yourself clinging to Doma once again. You tried to get up, but..
{If you know you know} "Doma I hate you." you mumbled under your breath. "Oh, but (Y/N)-chan! That's not what you said-" Doma started. "No! We are done here." you stopped him quickly. "Let's go get Rui.." you said. "Okayyyy" Doma whined. You got up and fell to the floor. Doma checked to make sure you weren't hurting yourself again just to find out.. "Damn, I went hard, huh?" "Yeah, you did Doma." you answered. He lifted you up bridal style and carried you to Rui's room.

You and Doma approached Rui's room and Doma opened the door since you could no longer move temporarily. Rui was still sleeping peacefully so the two of you decided to let him sleep. You went to go eat breakfast and Doma went to go buy his own food. {Yes. Doma does need blood to survive, but he is like Tamayo and Yushiro.}  You were eating breakfast and you heard Rui cry. You didn't know whether to wait for Doma or suffer through the pain to get to your child. You decided to try and push through the pain and slowly walked over to get Rui.  "Mama!" Rui cried. "Hey, buddy!" you said softly. "What's wrong?" "I had a bad dream!" he sobbed. "What was it about?" you asked. "That the man that was on his knee. He came back hand took you away from me and Daddy!" Rui explained. "This again?" you thought "Why is he so scared of him?" "Well, would you like to have some breakfast?" you asked "Y-yea" Rui whimpered.

You cooked Rui some breakfast with the leftover blood Doma did not eat/drink. {Idk k? T-T} Then you heard your crow come through the window. "Caw, Caw! Head to the corps headquarters! Caw, Caw!" "Mama? Do you have to leave?" Rui asked. "I'm sorry baby, I do." you answered.

You got ready to go and headed over to the headquarters. You then received a mission. You had to go help a younger division of demon slayers.

Once you reached you found someone running out of the forest. "Please! Help! Anyone!" The person yelled. You ran up to him and it hurt so badly. "God damn it Doma!" you thought. "Where is the demon located?" you asked. "Oh thank god! A hashira! The demon is located in the middle of the village! We managed to get everyone out, but the demon won't stop attacking!" The demon slayer explained. "No problem! I'm on it!" you exclaimed. You ran as fast as you could to the demon and saw the demon. It looked at you and froze. You prepared your sword for battle and the demon walked towards you. "Little sister?"
