There are around 184 Mikayuu ff in AO3. I read most of them so… I thought, maybe… I’d be of some help?
Ignore the order, please. These are my favorites but I can’t decide which’s better tbh
I hope someone finds this useful ^^

What other people don’t know about Mikaela is that behind the facade of tranquility he wears on the outside, there’s a weakness he never let the others see, not even Yuuichirou. Even before vampires took over the world, Mikaela didn’t allow his dark past in his everyday life. When Mika comes back from Ferid’s more exhausted than usual, Yuu demands to know what’s going on.
Angsty but cute :’) <3
This writter’s so good and the characters are so in-character I strongly believe it could have happened in canon.
To Be A Family
Glimpses of the daily lives in the Hyakuya family after the apocalypse and taken captive by the vampires.
The hyakuya children being cuties and showing Yuu what family means <3
Mikayuu as kids <3 !
Lots and lots of fluff.
I highly recommend.
Do I Wanna Know
Guren Ichinose runs a boy’s love cafe in Tokyo, to spite his family and because why not. Mika works there with a crew of young men.
One day, a familiar face from Mika’s past shows up for his first day of work, and nothing is the same.
Mikaela is a Reaper, who is sent to the human world as punishment for skipping out on his work, but what happens when he becomes friends with the person he’s supposed to reap? How is he supposed to separate work from his personal life when death is constantly around him?
Angsty in the latest chapters.
It doesn’t have as many kudos as it deserves.
The AU is much better than it seems! You’ll actually be surprised.
He begged, “You can take everything – everything, so please. Please don’t take Yuu.”
500 years; 6,000 months; 182,500 days; 4,380,000 hours.
What a terribly quiet world it is.
A world without Yuu.
After Nagoya’s failed mission, an unsteady truce is formed between Shinoa’s squad and Mikaela Hyakuya, making Yuu feel conflicted inside. On one hand, he’s got Mika back, his friends are alive, and they seem to be trying to be civil with each other, even if it’s just for his sake. On the other hand, Guren is being held captive by the vampires, Shinya has just given them a mission Yuu doesn’t like, and Mika… Yuu doesn’t really know what Mika is feeling.
Maybe not even Mikaela knows what he’s truly feeling, after all.
Everyone’s so in-charater it’s perfect.
I wish this happened in the manga…
The war’s over and the world looks forward to a brighter future ahead of them. Mika and Yuu have survived the worst, but soon find that they still have one more challenge left to overcome.
Wait a Minute
There is a reason you don’t mess with people’s feelings.
I’m Right Here
Guren struggles to face the future after a recent divorce. Shinya’s desperate to run away from his past. Yuu just wants a family, whereas Mika’s absolutely terrified of his. Nothing’s as easy as it looks on the surface and all four of them have definitely got issues to face before they can even grasp a semblance of happiness in their lives.
Somehow, a chance meeting at the local supermarket puts into motion a set of events that will finally change their lives. Whether it’s for the better or for the worse is another matter entirely.
PAIN.SUFFER.I CAN’T EAT. OR SLEEP ANYMORE. SEND HELP. DON’T READ IF YOU’RE TOO SENSITIVE. THE ANGSTIEST(?) SHIT EVER. I NEED THERAPY NOW. I STILL HAVE NIGHTMARES.
MIKA DESERVES SO MUCH LOVE. MIKA’S AN ANGEL. PLEASE SAVE HIM.
It’s a gureshin fic but, in my case, I could barely even notice with ALL THE ANGST.
A Musical Matchmaking
“Who died and placed Ferid as the moderator for the Theatre Club?”
“The real question is: why you still decided joining it?”
Arms of the Ocean
Ever since his beloved family was murdered, Yuu’s dreamt of Mika being alive. Over the years their dream meetings won’t stop reoccurring with Mika growing older alongside Yuu.
Fate must love being cruel to Yuu because there’s no way his dreams are real. After all, dreams are made up in your own head and Mika is dead…right?
Driving with You
Yuu sneaks into a car (Kimizuki’s) and drives off and Mika takes a car to see his sick sister. The two crash (literally) into each other and change their lives completely.
A Latte of Mishaps
Wherein Yuu is a barista at a cafe and Mika is stressing over his research paper that is due at the end of the week.
Based on “Little Red Riding Hood” by Charles Perrault.
Fast Food of the End: Do You Want Fries With That?
Mika is a poor university student working at McKruldo’s in order to make end’s meet. He hates his job, but it was the only place that would hire a kid with a temporary address. Yuu on the other hand, has his own apartment that he lives in while attending university, but as a stipulation of getting his own place, his parents require him to work at the fast-food restaurant where his uncle is the Assistant Manager. Working at Hiiragi Fried Chicken is a drag, but Yuu figures that at least it’s better than McKruldo’s across the street.
One day, Mika’s sweeping the parking lot of McK’s in order to get away from the General Manager’s constant sexual harassment, when he sees a black-haired boy cleaning the windows at HFC, their main competitor. Their eyes meet, and…
Our eyes met, and everything around me began to fill with colors beyond imagination.
Cute soulmates AU.
A Dance on the Spider’s Web
If anyone ever dared to look Yuu in the face and say that life of an idol trainee must be idle, he would punch them in the face. If anyone dared to say the same thing to Mikaela, they would be needing a spot on the nearest cemetery.
Singing, dancing, and acting on a daily basis, a nine-people idol unit begins the journey towards their debut. Little do they know about the truth in the rumours surrounding their group from the days before it was even founded. Show business is ruthless to those who cannot adapt - and even worse to those who can.
First chapter is the funniest thing ever.
When his delinquent best friend, Yuuichirou Hyakuya, almost got himself hurt in a fight, the head of the student body, Mikaela Hyakuya, decided to abandon all of his charismatic charm to teach his friend a lesson.
There’s a boy that has always attended Shinoa’s parties. His name is Mikaela, and he’s the cutest person Yuichiro has ever seen.
Yuu is so akward and Mika’s a prince charming (◡‿◡✿)
When Yuu first escaped from Sanguinem and met Lieutenant Colonel Guren, he couldn’t help himself. He broke down, he became depressed and he felt drained of the all the life he used to have.
Cute scenes between Guren and Yuu. It has more Mikayuu than expected(even though Mika’s “dead”, I mean).
I actually believe all fanfics here deserve a try. We were blessed with great writters in this fandom (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
Plus, there are some stories with a lot of potential but, since they’ve barely even started, I didn’t think I should have added them.
