Another Diabolik Lovers story with children that I’m pulling straight from my head...

AU Family: “The House at the End of Nothing”

Family: Laito + Yui + Haruki (and a baby in the womb)

Style: Heavy and silent atmosphere — everything carries a strange weight.

---

The House

○ I like to imagine that Laito and Yui live isolated and alone.

○ It’s in the middle of an ancient forest, where the fog never lifts, not even during the day.

○ The house is large and vintage, but decaying. The windows are tall and dusty, the floor creaks as if protesting every step.

○ There are old tapestries with strange symbols.

○ A pendulum clock marks the time with a dry tock, like a sentence.

○ One of the rooms was turned into a sewing room (Yui hand-sews clothes for Haruki and the baby).

○ Laito spends most of his time upstairs — in the old bedroom he used during his teenage years, now filled with Latin books, old letters, and a sweet, rotten smell (like dead flowers).

○ The kitchen is always cold. There’s no modern stove, just an old burner that Yui learned to light with matches.

---

Family Routine

Morning

○ Yui wakes up early, exhausted. Sometimes she vomits (pregnancy and nerves).

○ Haruki is still asleep — usually curled up too tightly for his age, with dark circles under his eyes. He sleeps clutching one of the eyeless teddy bears Laito gave him.

○ The first thing Yui does is check if he’s warm — he gets fevers often.

○ Then, she goes downstairs to warm goat’s milk (Laito doesn’t allow her to give human milk — “You need to feed the one inside you now, not the one that’s already born.”)

Noon

○ The house falls into silence. Deep, stifling silence.

○ Laito usually shows up around this time, smelling of blood, cigars, and sweet cologne.

○ He kisses Yui forcefully and tries to play with Haruki, but the boy pulls away.

○ Sometimes, Laito says he’s going to “teach” something — which means locking himself in the attic with his son.

○ No one knows what happens there, but Haruki comes back with charcoal-stained hands and empty eyes.

Afternoon

○ Haruki draws on the hallway wall with chalk Yui hides in a jar.

○ His drawings are always the same: a woman with stitched eyes, a man with a crown of thorns, and a child with no mouth.

○ Yui cleans it all before Laito sees.

○ When she erases them, Haruki screams:

> “She’ll get mad if you erase it! She’s coming back tonight!

○ Sometimes, Laito falls asleep in the middle of the afternoon, exhausted. That’s when the house breathes.

○ Yui uses that time to bathe Haruki, make tea, and sew. Sometimes she sings softly, always glancing over her shoulder.

Night

○ Haruki only sleeps if Yui holds his hand.

○ The room is dark, but Yui keeps a small candle burning. He cries if she puts it out.

○ Laito demands Yui in bed with him, but she tries to negotiate to stay with her son.

○ She almost always loses.

○ Haruki then hears the sounds from his parents’ room — sometimes whispers, sometimes screams.

○ Once, he tried to block his ears with candle wax. He only stopped when Yui caught him.

Impactful Moments

1. The first time Haruki bit someone

He had a fever and was starving. He was dizzy, and Yui took too long to prepare the milk.

When she knelt to hug him, he bit her clavicle hard, his eyes completely red.

Laito smiled from the doorway.

> “He’s awakening...”

2. The dance in the empty room

On a rare day with softer rain, Yui put on an old record.

She picked Haruki up and danced slowly with him pressed against her belly.

He asked:

> “When my sister is born, will you still carry me?”

Yui froze. She didn’t answer.

3. The hallway of the “breathing” house

Haruki swears the north wing hallway breathes. He hears whispers coming from the cracks.

One night, he drew a huge face on the wall with charcoal.

> “She lives here. She wants to come back.”

Laito saw it and only muttered:

> “I knew he’d inherit it.”

Dynamics Between Them

Laito x Haruki

○ Laito is both fascinated and impatient with his son.

○ He sees in him what he lost in himself — but is also irritated by so much weakness.

○ He constantly says Haruki needs to “wake up,” to “learn to feel pleasure in what frightens.”

Yui x Haruki

○ A strong bond, but marked by pain.

○ Haruki clings to Yui as if she’s the last safe thing in the world.

○ Yui loves her son, but fears what the environment is shaping him into.

○ Secretly, she writes letters for him to open “when he’s old enough to leave.”

Laito x Yui

○ Toxic, erotic, suffocating.

○ Laito manipulates her with the idea that “she belongs to him,” that “no matter where she runs, she’ll always come back.”

○ Sometimes he’s too gentle. Other times, too cruel.

○ Yui is trapped between fear and emotional/psychological dependence.

○ She believes there’s nowhere to go. And that’s worse than any physical prison.

I decided to get this AU out of my head, so I made some headcanons... I hope you like them ;⁠-⁠)

Well... English is my native language, so please forgive me for any mistakes ✊😔

⚠️ TW: Unwanted Pregnancy, and Child Death

─────────── ⋆ ⋅°₊ • ୨୧ ‧₊° ⋅⋆ ──────────

• Yui's pregnancy came as a result of an accident, a moment of misplaced affection and exploitation. Shu had no interest in becoming a father, and Yui was initially overwhelmed by the idea of bringing a child into such a broken world.

• Despite the initial shock, she made a choice to carry the baby, believing it could give her a reason to live beyond the endless torment.

• The pregnancy was never celebrated. The Sakamaki brothers didn’t care. They mocked and ignored her every step of the way.

• Shu’s indifference was clear from the start. He barely acknowledged the pregnancy, treating Yui as if it were just another inconvenience.

• Ayato, as usual, expressed possessiveness, making claims like "If the kid’s mine, I’ll raise it my way." Yui couldn’t even get a moment of peace from him.

• Laito was more detached, mocking her condition by calling her "a breeder" and making jokes about the baby’s future.

• Subaru, though silent, was visibly affected by the news, but never expressed it. He avoided Yui more than ever, retreating into himself.

• Kanato, on the other hand, showed a rare moment of discomfort, questioning the existence of the baby as if it were a threat to his position in the family.

• Yui was determined to keep the child, even when the world around her was a constant reminder of her suffering. The pregnancy gave her a sliver of hope, something to live for amidst the chaos.

• There were nights when Yui would talk to her unborn child, promising it that she would protect it no matter the cost. She imagined a life where she could be a real mother—one who could show her child love and care, despite everything.

• She believed, deep down, that the baby would be different, that it could somehow escape the darkness of the Sakamaki mansion.

• When Adam was born, the brothers remained indifferent as ever. There was no celebration, no joy—just the same cold atmosphere that filled the mansion.

• Yui was alone in the delivery room, and the only sound that echoed through the space was Adam’s first cry. It was a sound Yui would cherish forever.

• Even though the mansion didn’t feel like a home, in that moment, Yui believed she had created something beautiful, something innocent.

• Adam was an unusually calm child, even in such a hostile environment. He rarely cried and seemed to seek comfort in Yui’s presence.

• His big, innocent eyes would follow her movements, and he would reach for her hand whenever she was near. Yui loved those moments, when she could feel his warmth and touch, even though her life remained harsh and unyielding.

• At times, Adam would try to reach for the other brothers, but none of them ever truly reciprocated the affection. He would eventually return to Yui, finding solace in her arms.

• Adam’s death was a horrific accident.

• One day, while exploring the mansion’s grounds, Adam wandered off and accidentally tripped down a flight of stairs. The fall was enough to cause severe trauma to his tiny body.

• Yui found him almost immediately, her heart shattering at the sight of her son’s limp body. She screamed, but Shu’s only response was a cold, detached glance.

• Ayato acted annoyed by the inconvenience, and Laito treated it as a mere spectacle. Subaru was lost in silent guilt, unable to process the devastation.

• Adam’s death was the breaking point for Yui, and her hope for a better future died with him.

• Yui’s grief was quiet but all-consuming. She couldn’t understand why the child she had fought so hard to protect had been taken away.

• She often found herself staring at his empty crib, unable to comprehend the loss. Shu showed no empathy, and the others didn’t seem to care.

• In the silence of the mansion, Yui carried her grief in solitude. Her only solace came in the form of dreams, where she saw Adam running through a field, laughing as if nothing had ever hurt him...

• Teniendo en cuenta que Sentinel fue el principal asistente de los Prime, eso deja como algo bastante obvio que conocio a Starscream, Shockwave y Soundwave, que eran miembros de la Guardia de élite.

• Sentinel y Arachind, como dije anteriormente creo que tienen una relación tipo "amigos con beneficios", pero seguro solo son eso y son mas como colegas o amigos muy cercanos.

• Puedo apostar a que Sentinel durante las reuniones de los Prime, se quedaba medio dormido... mas si hablaban de poesia.

• Después de cada reunión con los Quintessons, asegurado un buen lavado.

• Sentinel de seguro cuando estaba borracho, pedia que lo destrozaran.

Lamento si fue muy corto, pero es lo que tenia hasta el momento.

Si quieren puedo tratar de hacer headcons de Sentinel x Personaje.

Inglés.

• Considering Sentinel was the Prime's main assistant, that makes it pretty obvious that he knew Starscream, Shockwave, and Soundwave, who were members of the Elite Guard.

• Sentinel and Arachind, as I said before, I think they have a "friends with benefits" type relationship, but they are probably just that and are more like colleagues or very close friends.

• I can bet that Sentinel during the Prime meetings, fell half asleep... especially if they talked about poetry.

• After each meeting with the Quintessons, a good wash is ensured.

• Sentinel surely asked to be destroyed when he was drunk.

I'm sorry if it was too short, but it's what I had so far.

My muse was given truth serum. Ask them questions on anon and they’ll have to answer honesty. They must answer no matter what the question is.

Gdzie Ron Weasley jest agentem FBI, a Blaise groźnym przestępcą. Ron musi złapać Zabiniego, ale jak zauważa Blaise, Ron ma do niego słabość, co Zabini wykorzystuje, by uciec z kraju.

Gdzie Sam Wilson jest aniołem, a T'Challa człowiekiem, który je (anioły) widzi. T'Challa zakochuje się w nim, jednak wie, że nie mogą być razem, więc znajduje sobie żonę. Gdy umiera, Sam odprowadza jego duszę do Czyśca i tak panowie się poznają.

Gdzie Dean Thomas jest mordercą i opowiada jak zabił swojego męża, Seamusa Finnigana. Wyjawia dlaczego to zrobił

Gdzie Leo pośmiertnie opowiada o zasadach w jego świecie (tj. choroba kwiecistych płuc i system bratnich dusz) z perspektywy osoby aseksualnej (tu też warto wcisnąć to, że tylko osoby zakochane widzą kolory)

Gdzie Pietro Maximoff jest nocnym łowcą, a Clint Barton faerie. Pietro próbuje pokazać, że nie każdy faerie jest zły tak jak Meliorn

Gdzie Hercules Mulligan jest super bohaterem, a Lafayette zwykłym informatykiem. Mężczyźni zaczynają badać sprawę tajemniczej śmierci Jamesa Madisona.

Gdzie Sam Winchester opowiada o swoim życiu w Piekle, zanim poznał innego demona, Gabriela.

Gdzie Oryński (z książek R. Mroza) razem z Chyłką są wampirami - wegatarnianinami i próbują przekonać innych, że nie trzeba pić ludzkiej krwi, co kończy się śmiercią jednego z nich.

(wzorowane na arcie!!) gdzie Castiel Novak jest policjantem, a Dean miejscowym złodziejaszkiem, który nałogowo chce być wsadzany do więzienia przez Casa.

Gdzie Castiel Novak jest synem Demeter, Dean Afrodyty, Gabriel Hermesa, a Sam Winchester Ateny. Cała czwórka jest następcami wielkich Herosów, tj. Nico di Angelo, Percy Jackson itd. Cas, Dean, Sam i Gabe muszą pokonać zbuntowanego Boga i go zniszczyć. Misja jest od początku skazana na niepowodzenie, ale herosi uparcie chcą ją skończyć. W tle jest depresja Sama, Destiel i zmartwiony Gabriel.

Gdzie Seamus pracuje w warsztacie samochodowym Deana Winchestera razem z Magnusem Bane'm i podrywa klientów, do czasu, gdy poznaje Deana, świeżo upieczonego studenta malarstwa.

Will Treaty jest Avengersem, a Gilan jest sekretarzem samego Tony'ego Starka. Panowie poznają się, gdy wściekły Gilan rzuca obelgami na biednego Willa, bo ten zalał mu kawą dokumenty.

Może druga część??
