NOTE: Okay before I start this I just want to inform you all that this is made up, so you are Aizawa's niece you are his 'sister' (remember this is all made up) daughter. So right now you are living in the Class-1A building.

(M/N)-Mom's Name

︿﹀︿﹀︿﹀︿﹀︿﹀︿﹀︿

"Uncle Shota, I'm bored." you whined, it was morning but you thought everyone was asleep still "Then do your homework." you gave him a pout look "I already did it," then suddenly you heard laughter "Uncle Shota, can I go play with your students!!? Pleaseee" you begged "I promise I'll behave" you begged like you were some kind of puppy, Aizawa sighed "Alright, just because you are my favorite niece," he says giving you a light smile while patting your head, you giggle "Yeah, right, I am your only niece," you smiled then left.

Aizawa is a person he keeps to himself, but he does have a soft side especially for you, his sister, and his students. He won't show it, but he does admit it, especially with you since he has always been there for you, especially since the death of his sister.

You skipped to the living room area and saw half of the students there you smiled happily seeing your favorite UA friend 'Toko-kun!!" You ran up running to him and hugged him, "Good-morning everyone!" everyone said good morning to you and all the girls gathered around you "Oh you're so cute (Y/N)-chan!" "Your dress is so cuute." you enjoyed being groomed and complimented by the girls in Class-1A you then skipped over to where Tokoyami was seated "Good-morning, (Y/N), how are you doing?" he greeted "I'm fantastic! Always have, always will be!" you gave him a wink and thumbs up. Before he could say anything else Dark Shadow appeared "No wonder that voice sounded familiar, my (Y/N)!" "Shadow-kun!" he picks you up and hugs you, he began throwing you up in the air and catching you while you kept laughing "Oh I almost forgot wait right here Toko-kun, Shadow-kun!" you stood up and head to the kitchen.

Tokoyami POV

I watch (Y/N) leave to the kitchen I smiled to myself, "Hey Toko-kun" says Ojiro, Jirou and Shoji chuckled at the name, I growled a bit "Yes?" "(Y/N)-chan seems to have quite a liking to you, its cute." he says "And a bit weird." Jirou says I gave them confused looks "How so?" "I mean no offense, you are cool to hangout and talk to, I just couldn't imagine you getting along with kids." She says "Your point?" I ask "I mean you have a dark and mysterious vibe type thing," I thought about it for a bit, it did make sense I remembered I tried to help this little girl one time, but she had tried to avoid me, maybe it was either Dark Shadow or my appearance. "Toko-kun, Shadow-kun!!" (Y/N) is riding on Sato's shoulders "Me and (Y/N), made these apple pies last night, she helped me by deciding what I should make so I can use for my quirk, and immediately her suggestion was apple pies." says Sato "Mhmm, I thought Toko-kun and Shadow-kun would be happy if they ate the pies we baked!! Sato is great baker!!" "THAT'S ADORABLE!!" Midoriya and Uraraka spouted, I blushed "(Y/N) you're so adorable, here why don't you make the first cut." He gave (Y/N) the spatula as he shows her how to cut "Awe Tokoyami it's like you're a dad!" Kaminari stated "He totally is I remembered one time I saw him bandaging her knee while Dark Shadow was trying to make (Y/N)-chan laugh." my face flustered into a deep color "Oh Yeah, well I saw them one time sitting outside, Tokoyami was reading to her poems." I felt as if my soul was leaving my body "AWEEEEE" "Somebody is blushing!!"

(Y/N) POV

I grabbed the first plate and gave it to Tokoyami "Here Toko-kun, you have the first taste," he thanked me then picked up the fork and took a bite "(Y/N), its delicious." he smiled, "I'm happy you like it!!" "Here, (Y/N)-chan, sit next to Tokoyami and eat your pie also, Ribbit." "Thank you Tsu-chan!" I began to eat my pie while I share with Dark Shadow, "(Y/N)," I looked up at Tokoyami "Hm?" "I appreciate you thinking of me and Dark Shadow, it makes me happy." he smiled, I smiled and hugged him "Oi, (Y/N)-chan I have a question for you." Jiro asked "Yes?" I said smiling "Why do you like Tokoyamii so much?" Jiro asked I thought about it for a second, all eyes were on me waiting for my answer, "Well, HE IS SO COOL!! He teaches me many things! He and Dark Shadow are fun to play with! He takes care of me when I am sad or have ouchies! I LOVE TOKO AND SHADOW-KUN, they are like my big bwothers!" I said "Oh yeah! I love you too, my (Y/N)" Dark Shadow lifts me up again as he holds onto my arms while I swing my legs.

Tokoyami POV

(Y/N), loves me? I thought "OH MY GOSH I SWEAR THAT IS SO CUTE, MY HEART CAN'T TAKE IT!" Hagakure says, "I agree," "Tokoyami, you are such a softy!" Kaminari teased, I blushed I wasn't embarrassed, most likely I am flattered. I will admit, I feel the same way for (Y/N) I see her as a little sister, I care for her, she is my pride and joy. Once I become a hero, I will most likely be her hero, I will do anything to protect her and make her feel safe and happy. I promise that I will fight for her with my life. I stood up then (Y/N) jumped into my arms "(Y/N), would you like to play a game?" her eyes sparkled with excitement "Yes!!" "What would you like to play?" I asked "Let's play hide and seek, you and shadow-kun are good at this game, but I will win this time!!" she smiled I nodded "Hey can we play too?" ask the girls "Yeah, I want to join in too!" "C'mon Deku, loosen up!" Uraraka says "Yeah, this could be fun." Everyone has joined in the game, I have found everyone but (Y/N). "Where is she hiding?" "Come out, Come out where ever you are (Y/N)!" "Huh, where could she be? She could be anywhere?" "She is not in the vents" Todoroki says "Why would she hide there?" "Well, she is still a child, it is possible she could fit herself in tight spaces" Momo exclaimed "Huh, well Tokoyami I think this time she has finally beat you." "OH HECK NAH, I'll find (Y/N)!!" "Have we looked everywhere?" "Yeah we have!" "Well not everywhere.." we all faced Mr. Aizawas room and cringed "Why don't we just ask him?" "Okay, Go ask him Tokoyami!" ugh, of course they meant me I knocked on the door I waited for a couple seconds then the door has opened "Hm? Oh Tokoyami, did you need something? Well, do you all need something?" "U-Uh have you seen (Y/N)" "Why? Is she causing you trouble?" "No sir, we're playing hide-n-seek with her." "Yeah and she is the last one to be found!" "So, would it be cool if we just looked around your room, please sir!!" Aizawa sighed "Sure I guess, just don't make a mess, I need some tea anyway." we all let out a breathe we didn't know we were holding in. "Mr. Aizawa is scary, oof" we went into his room and nothing there is no sign of a child being here. "Well looks like (Y/N) wins." we exited his room to see if she would show up, she didn't. I began to worry for her "(Y/N)! You can come out now! You won!" no response until we heard giggling it was near by but we were in the hallway, unless, I smirked I head to my room I opened the door, nothing, but I had an idea I whispered to everyone else "Follow my lead," I nodded, then I cleared my throat "Oh my, Dark Shadow, where could our precious (Y/N) be?" I say hearing a faint giggle "Huh, I don't know Tokoyami oh where could she be!?" He says holding in his laugh I quietly got on top my furniture and motioned everyone to close my room door making (Y/N) think we left I soon saw a little figure crawling out the bed then I grabbed her making her yelp, "Found ya (Y/N)!" says dark shadow as he tickles her she laughs I then carried her out from my room "I thought everyone left and I crawled out under Toko-kuns bed" she says everyone laughed and chatted after we head downstairs.

It was already evening, I had spent time with (Y/N) all day, I can't help but feel warmth when she is around especially when she would ask me to read poems for her while we lay under the tree shade soon she would fall asleep on me and I would hold her as I also rest my eyes. I glance at (Y/N)s way she was fiddling with something I walked towards her "What are you doing (Y/N)?" I asked she turns her head and smiled handing me something "I was doing origami, I made paper cranes," she said smiling "This small black crane is Shadow-kun, and this big one is you." I smiled "Thank you (Y/N), small things like this makes me happy, you know that?" her smile became bigger "Really!? How about I draw you something!?" I chuckled "I always keep your drawings (Y/N)" I say petting her head I then looked at the three cranes on my hand, three? "(Y/N), what is this (Favorite Color) crane?" "Oh! That one is me!" I smiled and picked her up as I swung her around, the way she acts, so innocent and naive she reminds me of a little angel, I then saw she yawned "(Y/N), are you tired?" I asked she shook her heard, but I knew she was I then carried her inside heading towards the guest room as I tucked her in she takes my hand "Toko-kun, can you read me a story, or more poems please." she says I smiled and nodded "You never get tired of poems right (Y/N)?" I asked she shook her head and smiled "Nope, I love it when you read poems to me, I don't think it's boring." she says I sat in bed as she sat in front of me as I held the book in hand as I read to her. After I finished I find myself tired "Well, (Y/N) we should get some sleep," I shook her "(Y/N)?" I soon realized she fell asleep I didn't want to wake her at all I slowly got under the covers with her as I try to slip away but she holds my hand again "Toko, stay." I was shocked "I-I can't (Y/N) I must-" "Pleasee, I'm scared the bad people would get me.." That's right.. I forgot... her mother Mrs. (M/N), she was killed by villains... (Y/N) witnessed her mothers death.. and at such a young age, also nobody knows (Y/N) father whereabouts. I couldn't contain myself as I moved my body and got under the covers I held onto (Y/N) "Y/N, I promise no bad people will ever lay a hand on you, Dark Shadow and I will always be there to protect you, understand?" she smiled softly and nodded "Okay Toko-kun." she says as she gave a quick kiss on the side of my beak "Goodnight, Toko-kun I love you!" she says as she snuggles in my arms, I was shocked, my emotions are building up, in a good way, I am lucky to be friends with this child, and her name is (Y/N) (L/N), I held tightly onto her "I love you too, (Y/N)" I soon fell into a peaceful slumber.

BONUS

"Have you all seen (Y/N)?" Mr. Aizawa asked everyone shook there heads "Last time we saw her she was with Tokoyami," Jirou mentioned "Maybe he is tucking her to bed?" Koda says "OMG LET'S GO SEE!" Mina says excitedly "Why are you excited?" Sero asked "Well this is Tokoyami we're talking about, and (Y/N)!" after that was said everyone had the idea what she meant and they all head to the room (Y/N) was staying at "Could you not run," says Mr. Aizawa as he opens the door they saw Tokoyami and (Y/N) sleeping "Oooooooh so cuute!!!" Mina squealed quietly trying not to be too loud, she snaps some photos "Hey can you send that to me?" Jirou says containing herself from laughing "Although though this is touching, you can't take photos that is rude!! Should I wake him sir?" Iida asked his teacher, Mr. Aizawa sighed and closed the door "Leave em' be," he says before everyone left he called Mina over and whispered to her "Can you send me those photos also?" he smiled lightly.
