Isagi? Nah, Usagi!

Summary:

Basically Isagi wakes up one day in blue lock with bunny ears and a tail. Follow him on this adventure where he desperately tries to hide them from his teammates and gets fawned over in the process!!

(This was somewhat inspired by Cat-Boy isagi by @kiiiyosei in that it got me thinking about this trope!! But i thought instead of a cat boy id give isagi rabbit ears instead since his name is close to Usagi which is supposed to be rabbit or hare in Japanese)

Notes:

Hello Lovelies!! I hope you all enjoy this fic as much as I had fun writing it!! A bit of a warning that uploads may be inconsistent as this is sort of a side project/break from my main fic “The Heart in Disguise” but i’ll still try my best to keep up with this one too!!

Chapter 1: An unpleasant surprise to wake up to

Chapter Text

“What.

The absolute.

FUCK IS THIS!?”

 

A shocked screech rang through the halls of blue lock at approximately 2am, a time when absolutely no one should be so much as dreaming of being awake.

And yet still someone was. That someone being none other than the heart of the facility, Isagi Yoichi himself.

The raven-haired boy stared at a vision of himself in shock, but surely the boy he was seeing in front of him couldn’t be him. No, the bathroom mirror must have been replaced with a computer screen or something,,, maybe the late hour was getting to him. He rubbed his eyes, splashed cold water on his face, pinched himself even!! But nope,,, nothing was working.

Eventually when nothing else worked to wake him up or get rid of the vision, the boy raised his hand above his head, heart all but stopping as his hand made contact with something way too soft.

“no, no no, no- JUST NO THERES NO WAY THIS IS REAL RIGHT NOW!!” the boy spiraled a bit, now wondering if he’d been drugged or was on some prank show,,, maybe he’d been hit with a soccer ball to hard and was now clinically insane as a result of some concussion,,, hell maybe he was in a coma- YEAH THAT HAD TO BE IT! Cause there's no way what he’s seeing right now is real, things like this didn’t happen, at least not in real life.

The boy looked up into the mirror again trying to catch his breath so as not to fully fall into a spiraling panic attack. The image that freaked him out so much, well the form he took that would probably haunt him in his nightmares, was that of his normal self, with the all too abnormal addition of bunny ears on his head. That’s right, two long fluffy droopy ears that framed his face and occasionally twitched slightly.

On top of that his hair was also suddenly slightly longer, or frizzier and took up the space where his ears should be- HIS EARS WERE GONE?! Wait but he could still hear, a little too well in fact. Yeah, that was the first thing that tipped him off that the rabbit ears couldn’t be fake.

He wondered if he turned around would there be a- “YUP I HAVE A TAIL TOO WHAT?!” the boy screamed internally as he reached behind him to find a lump wiggling against his lower back under his track suit. The sudden awareness of the tail made it much more uncomfortable under the fabric, but that could be dealt with later as he now had way bigger issues to deal with.

He had just woken up to pee and this was what he got, “damn what the hell man” he mumbled as he slowly slipped into some weird space between continuous panic and acceptance. Deciding that there was no point in holding things off any longer he stomped out of the bathroom, straight to ego’s office.

--------------

One knock,,, two knocks,,, three, “oh fuck it” isagi gave into his urges, banging on the door ready to knock the damn thing down until Anri came to it, yawning and mumbling something about blue lock needing a curfew. But she stopped, silence over taking her as she saw who was at the door and what he looked like.

The usually wide eyed womans eyes somehow were blown even wider as she stared at the boy in front of her, wondering if this was some late-night fever dream or just a straight up regular dream. Isagi sighed tears beginning to slightly sting his eyes as the panic of another person actually seeing what he sees set in. He nodded at Anri before looking down, gritting his teeth and closing his eyes to fight off any tears, he wasn’t a crybaby anymore, “yeah I know crazy right? I need help I don’t know what's up with,,, these.” He said pointing at his ears.

Before he knew it Anri was pulling him into the office, which was actually just an empty triangular room with a desk in the corner opposite to the entrance door and two other doors on the other side of the room. One door was slightly opened and seemed to have what looked like a woman's room through it, Isagi quickly put together that that must be where anri slept as she went through the other door and came back out with an annoyed looking ego.

---------------

After the same initial shock from ego followed by some tough interrogation over the possibility of the ears being a prank, Anri called in one of the nurses of blue lock to look at Isagi and check what was wrong. In the end she reported that she couldn’t figure out what had happened, and that aside from the ears and tail nothing else seemed abnormal about the boy. The only clue she could give was that she had heard rumors of similar situations throughout the medical field, stories of people waking up with animal traits, but they were only that, stories.

Still the fact that those stories even existed hinted at something more.

In the end they decided that there couldn’t be anything done for now, and that since his health was fine regardless isagi could go on his way and continue training as normal while they try and search for a specialist or anyone who may know something.

“Wait- You want me to go out there like this?! Like everything’s normal?!?!” The bunny boy asked as the nurse pushed him out of her office.

 “Yup! Unless you’d rather be sent to a lab to get poked and prodded” was her answer before ego tacked on “or fall behind your peers.”

Realizing the adults were right isagi fell into a shallow acceptance of his fate, too tired to think up reasons as to why this was a terrible idea. Ego and Anri (mostly Anri) quickly formed a solution to tell the public so that they wouldn’t get suspicious. Though Isagi had taken a large hoody to try and hide in, they knew eventually that wouldn’t work, so they’d frame the rabbit ears and tail as a sort of fan service special do to blue lock’s success, hoping that the investors wouldn’t mind and just see money.

As for the other blue lock members,,, Well the realness of the ears and tail couldn’t be explained away with editing magic or as fake accessories so they’d leave that up to isagi to deal with once he gets over trying to hide them.

——————

Now in the Changing room isagi sat tiredly in front of the mirror, only slightly less horrified by the ears he saw. As he tilted his head to look at how they moved he thought “You know if these things weren’t real or on me, they’d actually be kind of cute.”  

The idea was quickly shaken away though as he remembered the fact that he’d be facing his friends with these,,, things.

The boy now alone once more took the chance to change out of his track suit. He blushed as he looked in the mirror, realizing that the shorts ended right above his mid thigh. The boy huffed, wishing he had gotten a longer pair or sweatpants instead, before  remembered that the waste on those were higher and would more than likely be uncomfortable with the tail, not to mention he felt a lot warmer than usual. (rabbits have a higher average body temperature than humans)

Once the shorts were on he pulled over a lose shirt about two sizes too big. The shirt was long enough to where it reached just above the shorts, but its looseness was far more comfortable than the skin tight track suit he’d been initially wearing.

Finally he pulled on the large jacket he’d gotten, making his best attempt at tucking his ears under the hood. He’d to clip them down, but frankly that sounds like it’d hurt, and seemed to be more trouble than it was worth.

Now drowning in clothes, the raven haired boy caught his own eye  in the changing room mirror. He decided that despite the heat from the hoody and the way the clothes looked like they were eating him, it was a fair trade off in return for hiding his ears.

With that he said a quick prayer to who knows who and made his way back to his room to try and get some sleep.

Thankfully all three of his roommates, kurona, nanase, and hiori were still sound asleep at 5am, so they didn’t even notice as the bundle up boy slid under his covers and drifted off to sleep.

——————

“Isagiiiii, isagi-san wake up pleaseee”  A dark haired and tired Nanase stood at the foot of his teammates bed trying to shake him into consciousness but was only met by groans asking for more time as he dug further into his covers. “mmm just gimme m-second”

It was now 7am, meaning it was time for breakfast and soon after morning practice, and though they technically wouldn’t be in trouble themselves for letting isagi sleep in, the three roommates would prefer it if their friend wasn’t late.

“Enuff a-dis just pull the covers off an’ hit em awake!!” Hiori chimed in not wanting to waste any more time.

“Wait wha-“ before giving them any time to rebuttal the light-blue haired boy ripped the covers off of his teammate while simultaneously smacking his face with a pillow from his own bed. If it where anyone else he would probably feel bad, or worry they’d get mad, but since it was isagi he didn’t mind playing a little rough as he knew the boy would let it go.

“Mmmm ok im up im up!!!” Isagi loudly mumbled as he shot upright, surprised at the rude way he was awaken.

“That was kinda rude hiori” Kurona said as he finished changing and turned to see a shocked isagi with rabbit ears and an oversized hoodie. Wait- rabbit ears?!

The three roommates stared at isagi in shock now seeing the ears on his head. They hadn’t been able to see the top of his head with the large hood of his jacket pulled over his head, however now that head sat up in surprise the hood had slipped off, and revealed a pair of bunny ears sticking up, alert.

Isagi looked at all three of the boys, confused before remembering the events of a night prior “shit,,, I guess that wasn’t a dream-“ he mumbled under his breath.

Nanase was the first to speak, “I-isagi- are you aware that there are-“ “OH MY GOSH THEYRE SO CUTEEEEEE” hiori exclaimed cutting the boy off as he reached for isagi’s ears.

The blue haired boy quickly moved back, ears wilting to partially cover his now strawberry red face. “ack- please don’t touch they’re sensitive! And yeah they’re real,,,”

The boys gaped at the confirmation that the ears were real as well as the image before them that seemed way too cute and almost slightly lewd, Isagi wearing shorts in a hoodie way too big for him, red faced as he curled into a ball with fucking bunny ears on his head?! Yeah this was definitely a picture from some “steamy” romance manga.

Out of the three hormone filled boys kurona was surprisingly for once the first to recompose himself. “Where did they come from?” He asked, moving to sit at the foot of isagi’s bed.

The blue haired boy brought his hand up, lightly moving the ears from in front of his face in a way that almost made hiori’s heart stop “I don’t really know,,, they showed up last night and I went to ego and then the nurse” he shrugged shyly moving to sit up in his original position. “No luck. They couldn’t figure out what happened so I just gotta deal till they can. I was trying to hide them but I guess its hard since the three of us share a room” “ah I see,,,” kurona responded nodding.

Hiori Kurona and Nanase all gave a silent thanks to the gods that they were the one’s sharing a room with isagi, both because they were privy to this secret and because who knows what some of the pervs in blue lock would do if they knew! Not them though, they were respectful mhm!

“Ah ‘m sorry for tryin ta touch em then! I thought they’d be fake ya know.” Hiori said bowing his head in apology.

Isagi sighed again giving him a shy smile “Pft its ok, but what you really should be apologizing for is ripping my blanket off and hitting me though!!” he said giggling as he grabbed the pillow hed been using and attacked hiori.

Nanase bursted out laughing from the opposite side of the bed and Kurona huffed a chuckle of his own.

“Okokok I deserve that!!” hiori laughed softly as he stood up, finally evading isagis attacks “We should hurry up before we miss breakfast though!!”

Isagi dropped the pillow realizing the boy was right and quickly began trying to adjust his ears to fit under his hood again. When he realized he didn’t have a mirror and he’d have to ask for help he huffed and asked them to wait before leaving. “Mh Kurona can you help me with this”

Within less then a second Kurona stood in front of him ready to help. Despite Holding his usual bored poker face, Nanase and Hiori could see that he was practically glowing from the inside as isagi asked him to move his ears till you couldn’t tell they were under the hood.

Kurona always one to follow the other boys lead easily did as told while also trying to smooth out his all too soft and fluffy hair. “Isagi your ears are really really soft,,, and your hair too, even more than usual”

The boy just blushed trying not to squirm around too much at the feeling of someone else touching his ears. Though kurona was gentle, the entire situation felt way too intimate, and the sensitivity of his ears wasn’t helping, he felt almost as if the other boy was feeling him up in a way.

From their place in front of the door Nanase and hiori watched, extremely jealous of Kurona’s position and silently hoping they’d get to help instead next time. When Kurona finally finished isagi pulled his hood down, making his way quickly out the door past his friends, desperately trying to hide his blush. “So cute!!!” they all thought before quickly trailing behind.
