Katsuki and Shoto were sitting down stairs when they got a knock on the door, Shoto went and answered it.
"hello?" Shoto said confused
"Hi, uh im Kazuko, your son from the future" he smiled
"Uh, Katsuki!" Shoto called, Katsuki came through
"hi, who is this" Katsuki said confused
"uh, apparently he is our son from the future" Shoto said
"Really, i mean anything in this world is possible but wow thats extraordinary"
"Yeah" Kazuko nodded
"How old are you now anyway" Shoto asked
"15" he stated
"15! Wow, do i look ugly in the future" Kazuko looks down
"...you're not in the future" Kazuko said looking at Katsuki
"Huh, why" Katsuki asked
"You died giving birth to me in my universe" Kazuko said quietly
"Oh, so why did you come here" He asked
"I came to see you, i wanted to see you At least once, you see my quirk is Time travel and i though it would see you once then leave" he explained
"Ok then, Lets do something fun, with a son from the future" Katsuki smiled
Katsuki ran up stairs and grabbed a Polaroid camera and came back down "how long can you stay" he asked
"2 hours" Kazuko stated
"Thats not long" Katsuki said
"Also i may or may not have promised my parents i would bring you back for a little bit" The boy's hand went to rub his neck sheepishly.
"Uh" Katsuki looked at Shoto
"If thats ok" Katsuki looked at shoto
"Honey its just me from another universe" Shoto kissed Katsuki's forehead
"But what if they arn't like you and Ejirou"
"Oh i promise you they are like you"
Kazuko said smiling
"Lets go!" Kazuko said Grabbing Katsuki's hand
"But- ok fine" Katsuki sighed
"Bye?" Shoto said confused
And Poof they were gone
Katsuki and Kazuko were in a hallway the same hallway they were in before
"wait you weren't joking where is Shoto i thought you were some druggy" Katsuki stood in the same hallway as before except it was different.
Pictures of the couple and Kazuko where hung on the wall. The hall way had been done up and it was painted a pastel green.
"Wait is he here" A voice came from the living room
"I think so" another voice sounded
"Are you crazy you didn't give me time to think and i have no shoes on and its fucking freezing" Katsuki practically yelled, two men walked from the living room
"hey dont yell" a older looking Shoto walked over.
"Oh my god, you guys are old" Kazuko slaps Katsuki round the back of the head
"i- ow don't hurt me you little shit" Ejirou and Shoto laughed
"So you guys are from the future but alternate universe?" Katsuki asked
"Yep" they said in unison
"Wait, why am i here again" Katsuki was confused again
"You came to see future us?" Shoto said
"Oh yeah, hello" Katsuki waved akwardly
"Hi" Ejirou came over and hugged Katsuki
"you know i forgot how short you were" Shoto a small tear forming in his eyes
"Wow im being bullied here" Katsuki laughed "what year is it then" he asked
"Its is 2055" Ejirou answered
"2055! I would be, wait let me count" Katsuki said looking at his fingers counting
"i would be fuck what would i be" Katsuki said looking at Shoto and Ejirou
"You would be 40"
"40! Jesus christ, i would be old then I will be gray and ew" he pulled
"We are 40" Shoto stated rolling his eyes
"Oh yeah" Katsuki said putting his hand on the back on his neck sheepishly
"So I'm guessing you wont be staying long" Katsuki asked
"Sadly no" Kazuko answered
"i love you hair cut" He walked over to Ejirou, his hair had a under cut but was long at the top able to reach his nape.
"I need to do this on Ejirou, defiantly" Katsuki smiled catching eye sight with the male
"Actually you were the one that convinced me to get it" Ejirou ran his hand through his hair
"Really!, wow i have taste" katsuki said amazed
"Wait so are you guys married in your universe" Shoto asked
"Pffft no" Kastuki laughed "dont really want to"
"We understand, your nervous but trust me you will enjoy it a lot" Ejirou said
"Uh sorry to interrupt but Katsuki you have to go"
Shoto looked over at the male with a sad expression, Katsuki walked over and kissed them both
"keep that" Katsuki cupped their faces
"wait before i go do you guys want anything special" he spun around
"Special, hmm no this memory is enough for me" Shoto said
"Maybe to you i want a picture" Ejirou walked over and got out his phone and grabbed shoto and they all got a photo together
"wait where is Sakura" Katsuki looked around
"Sakura is at uni, here" Ejirou pointed to a picture of Sakura on the wall
"wow she has grown" The blonde male was amazed how grow up she looked
"Wait how old is sh-" Ejirou got interpreted
"Katsuki we have to go really" Kazuko was itching to go
"Oh yeah and she is 4, bye" Katsuki waved and went back with Kazuko
Once they arrived back at 2040 Katsuki took a picture with Kazuko in the polaroid camera
"keep this" Katsuki smiled and with that Kazuko left.
When Katsuki got back inside with Present Shoto and Ejirou he ran to Ejirou
"WE HAVE TO TRY THIS HAIRSTYLE ON YOU" Katsuki shouted
"did you have fun" Shoto laughed
"Yeah, i met you and you but old" Katsuki was ecstatic
"How old?" Ejirou asked
"40" The blonde replied
"Was i hot?" Ejirou smirked
"Of course, you has this amazing haircut" Katsuki kissed the male, avoiding squishing the new born the laid on his chest
"Will you guys still love me even when I'm wrinkly and crippled" Katsuki pouted
"Of course" Shoto said hugging Katsuki.
Soon after Katsuki cuddled with Ejirou and Shoto until Baby Kazuko needed feeding, Katsuki got up and took the baby off Ejirou, he lifted up his shirt to breast feed Kazuko.
"guys when i say Future Kazuko he had Salmon hair like pink" Katsuki was finished breast feeding and held the baby to his chest.
"Really?!" Ejirou said confused
"Yeah must have been Shoto's hair but mixed together" Katsuki smiled
"Maybe" Shoto said putting his hand on his chin
"Where is Sakura?" The male asked
"She is up stairs she was tired" Ejirou answered
"Ok, i want to cuddle" Kastuki asked, he quickly put Kazuko in the crib that was in the living room
"Of course" And with that Kastuki, Ejirou and Shoto cuddled on the sofa, watching a program.
