HAPPY BIRTHDAY TO @mjtheartist04 !!!!!🩷🩷🩷🩷

Happy Birthday to literally one of the kindest, sweetest, and funniest people I've ever had the greatest opportunity to meet!!! I swear anytime I get the chance to talk to this girl and just hear her voice and laugh it makes my heart melt.

Here's a little something from an ask you answered a while ago that I JUST couldn't stop thinking about... So I've indulged in a GenRika Mermaid/Pirate AU...🙈

MJ, you're an amazing gift giver- through and through, and you never fail to lift my spirits and show kindness, and to make people laugh. You're stories and AUs always make my day to see you on my dash, or to get a text. Your daily reminders and love filled messages do so much for me you will never understand. You mean the world to me, and you mean the world to all those 400 followers!! Today is your day, and I hope you are reminded of that all day today with nothing but love and support. I love you Pookie!!! 😘🩷🩷🩷

Joined my freind tassunas art comp on tiktok,(slinkyastasuna) and this is lowkey the coolest thing I’ve ever drawn me thinks.

I am also now Hyperfixating on carptaro. I would like to draw myself spoon feeding him cat food like you do with real carp. I need to learn everything about carp and make it about him

I feel like if Gyutaro were a fish he would be a carp, and Ume would be a koi. Because even though they are literally just the same fish, koi are regarded as beautiful and fancy and beloved, while carp are seen as disgusting ugly pests.

And obviously Himiko(tasunas oc) is a koi bc her oc loves koi :3

What if the angelic energy from Alastor's wound is what finally dispells the suggestion?

He's not compelled to listen anymore, though the thought pattern has still been in there a while. Just going to need to make some new neural pathways to work around that dark spot.

Ooh if Alastor did have the angelic energy in this AU that would make it interesting. Like, it flares up every time Vox speaks or makes a suggestion, because it's activating the hypnosis hardwired into Alastor's brain.

It snaps Alastor out of it but it's a very painful experience. Probably would make him work double-time just to avoid Vox.

The tiny mermaid Syalis was happy when humans were not yet hunting her kind. When the hunt began, her elders protected her, and she lost everyone she loved, one by one, until her heart turned into a piece of ice. There was a time when she fought against humans, but this did not decrease their numbers, but increased them. So much that the mermaids began to become extinct. The seas were polluted with blood and the power of her kind diminished, and Syalis fled… unwillingly. For centuries, she had no time to rest. Whenever she found a new place, it was discovered immediately. It's unclear whether she was trapped because she was tired or because she gave up.

Kanae gets injured and Akaza has an idea on who the culprit is.

[therabbitthatpostthings]

Kids will believe anything you tell them. You tell them to be good so Santa will bring them toys. You tell them to brush every night and a fairy will bring them money. You tell them mermaid scales grant wishes and you have the bravest 7 year old armed in their little yellow raincoat, determined to find a mermaid.

Frankly, (Y/N)’s guardian should have known that a headstrong kid like them would just march themselves down to the beach after school. It’s not like the signs weren’t visible but you never really think a child will do something until they do it. The guardian sighed reading over the red crayon on yellow construction paper: Gone To Find Mermade Wishs.

The fun was short lived as the clouds started to look heavier in the sky. They felt a bit of concern. That heavy weight a parent gets when their child isn’t in eyesight. “I’ll just go down there…” they thought, already out the door and walking to the beach. Surely such a small child could not have gotten mixed up in anything that dangerous.

Of course they couldn't have.

*•*

(Y/N) scooped up big bunches of sand into the bowl with holes in it. They swashed it around till all the sand was gone and the pretty shells remained. They stared inquisitively at the shells. They held the shells gently in their hands and watched as they fell into the bucket, with the intense seriousness that only a child feeling like their tracking an animal can have. (Y/N) had a steely gaze as their eyes surveyed the beach. No one was out on the beach (they had the common sense to stay inside). The seagulls squawked overhead, occasionally swooping down to grab at the creatures caught in the low tide. A group of them gathered near the edge of the pier. They looked to be picking at shiny blue stones. There was a sound amongst the squawking, it sounded like someone crying.

(Y/N) sprung into action, running over to them swinging their plastic shovel in the air. “Shoo! Shoo!”

They waved the bucket around, scattering the birds in the process. They heard a groaning and looked down. It was not a pile of blue stones but a tail! The blue tail was covered in bruises and scratches. (Y/N) leaned down to inspect when it started to move. They stepped back, finally noticing the body the tail was attached to. Its body was half submerged in the sand that stuck to its long black hair as it sat up on its arms.

“Y-You’re a mermaid!” (Y/N) yelled.

The mermaid jolted up. It looked over its shoulder quickly and took off in a crawling-sprint to the pier. (Y/N) gave chase, following under the mucky pier. “Hey! Are you okay? Are you a mermaid?”

The little mermaid was surprisingly quick with its limited mobility. (Y/N) watched as it hoisted its little body over the rocks and support beams of the pier. It climbed on the largest rock and disappeared behind it. (Y/N) climbed up on one of the rocks, “Hey! Are you okay!”

“Leave me alone!” the voice called out in a broken cry.

“Hey! I’m coming over!” (Y/N) called back despite the shouts to not to. They threw the shovel and pail over first, earning a loud ‘ow!’ from the mermaid and hoisted herself over the rocks. They tumbled down the side into the small puddle. The mermaid was sitting in the middle of the puddle. It was crying. The mermaid was small, probably about (Y/N)’s age, its back was dotted with blue scales that spread past its shoulders onto its arms. (Y/N) approached them slowly and reached to put their hand on their shoulder. The mermaid swiped his claws at their hands and hissed.

(Y/N) jumped back, cradling their hand, “Ow! What’d you do that for?!”

“You hit me!” He yelled back

“No I didn’t!”

“Yes you did! You stupid human!”

“Well- you’re a dumb fish!”

“I’m not a fish!”

“You look like one!”

“Well you’re ugly!”

(Y/N) gasped dramatically. They went clutching for the non-existent pearls not around their neck. “You’re mean! You can stay here, I didn’t want to be here anyway!”

The boy huffed, “Fine!”

“Fine!” (Y/N) yelled even louder. (Y/N) turned to try and climb the rock but it was too large for such a small child to make it over, especially without the aid of the smaller stones to step on. Defeated, they turn back around to sit down. They dramatically sat down in a huff opposite from the boy. “I’m staying!”

The boy rolled his eyes and huddled into the corner muttering to himself. He pulled his tail close to his chest and dug his claws into his arm.  (Y/N) could hear him sniffling. He was shaking. Scratches and bloody bruises covered his body. There were small spots where his scales had been picked off by the seagulls. They looked down at their own hands. The cut wasn’t deep on their left hand, it wasn’t even bleeding. Even if the seagulls put up the fight, there wasn’t much they could have done against the thick plastic of the raincoat. Even though (Y/N) was very upset about the mean words, they still wanted to help. This was a mermaid after all! And (Y/N) had a mission to complete! They moved closer and held out the red bandage to the boy. He didn’t notice so they tapped him lightly on his head.

His head shot up and he pressed his back into the sandy bank “W-What’s that?”

“A band-aid.” (Y/N) replied nonchalantly.

“What do they do?”

“It’s for your tail, you’re bleeding.”

He scoffed, “I don’t need it.”

“My teacher said if you don’t use a band-aid you’ll get sick?”

He thought it over for a second, he looked concerned, scared and finally hesitant but willing. He straightened out his tail for (Y/N) and motioned for them to put the bandaid on. (Y/N) carefully places a bandaid on each bleeding spot, all over his arms and on his cheek. Now that they could look at him, they saw he had swirling blue marks along his neck and lower part of his face leading up his bright blue eyes. He was already pretty pale, it made all of other features stand out even more.

“Why are you looking at me like that?” he asked

“Your eyes look like jewels.” (Y/N) answered matter of factly. They completely missed his embarrassed reaction as they wrapped the last band-aid around his finger. They held up their own bandaged hands. “Look, now we're matching!”

He let out a small giggle, “Thanks. I’m Giyuu.”

“I’m (Y/N).”

“I’m sorry I scratched you.”

“It’s okay, I’m sorry I said you were a fish. I know you’re not.”

“You do?”

“Yeah! You’re a mermaid and you grant wishes!”

Giyuu giggled again, “We can’t actually grant wishes. It’s something grown-ups say humans would hunt us for.”

“You mean that’s made up?” (Y/N) whined.

Giyuu shook his head, “It’s just a story.”

“Oh,” (Y/N) replied solemnly.

Giyuu noticed and moved to sit closer to them. “What were you gonna wish for?”

“To be a mermaid.” (Y/N) replied “I like swimming but I’m too little to go out on my own.”

“Oh,” He said. “If I had a wish, I would wish to have legs. I still want to be me, I would just like to walk on land sometimes.”

“Why?” (Y/N) asked.

“I don’t have any friends. All the other kids call me mean names. My sister and her friends are mean too!” Giyuu’s claws were digging into his arms again. He stared at the open crack between the pier bottom and rock. “They told me to go grab a rock from the surface if I wasn’t a guppie- and I’m not a guppie! One of those floating things got close to me so I swam and I got caught by the waves! Now I’m gonna die in this stupid hole cause I’m too small and I can’t get over this stupid rock!”

(Y/N) was quick to pull Giyuu into a hug. He sobbed into their shoulder. “It’s okay Giyuu, I’m your friend now.”

“Really?” he yelped

“Yeah!” (Y/N) cheered. “I’m your friend and I’m gonna help you out of this hole okay!”

“Okay!”

There was something about the strength of two kids who put their mind to something. For no good reason should two seven year olds have been able to lift themselves over a large rock with only the help of a plastic bucket and a lot of teamwork but, they did. The tide was still pretty low so (Y/N) had to carry Giyuu towards the water’s edge. Giyuu happily rolled in the bank, glad to be in fresh ocean water and not the murky puddle under a pier. He laid on his stomach letting the cool water run over his body.

“I wish you could come with me,” he lamented. “I think you would like it, sorry I couldn’t grant you a wish.”

“It’s fine, I’m gonna get bigger and swim farther anyway.” (Y/N) smiled “Could you come back tomorrow?”

“I’m probably in big trouble…” He sighed.

“Oh…” (Y/N) replied. “Are you sure you can’t come back?”

“I don't know..” Giyuu said.

“Well, you can take this.” (Y/N) held out their bucket. “Next time you come back we can collect more shells!”

Giyuu smiled, taking the bucket in his hands. He saw stuck on the inside was a deep blue shell, slightly chipped on the side. He handed it over to (Y/N), “Here! Remember me okay?”

“I will never forget you Giyuu,” (Y/N) smiled.

“(Y/N)!” The panicked voice of their guardian came from the shoreline.

“Oh no, I might be in trouble too.” (Y/N) shuddered.

“I’ll see you next time!” Giyuu called. He crawled back into the water and swam off once he was deep enough. (Y/N) watched from the shore as the plastic pail disappeared beneath the waves.

“(Y/N)! Are you okay!? What was that thing?!” Their guardian yelled.

“That was my mermaid friend!” (Y/N) cheered.

They wanted to argue with the child but were too relieved to be mad right now. “Whatever, come on it’s going to start storming!���

The two children, without even realizing it, had tied themselves to each other. Their destinies were intertwined on that beach. A friendship was born and a promise was made. Nothing could stop the hands of fate now.
