Mermaid's Deity
Prologue

one year prior to the series...

It's summer the sky is clear the sun is bright and Nishinoya Yuu was having the time of his life hanging out at the beach checking out cute girls! though it kind of sucked that they kept thinking he was in middle school or worse elementary... he shuddered as he swam out farther from the shore and and rolled on to his back to stare at the sky "Someday I'll be taller find a girl! a cute one too!?" he declared getting a few beach goers attentions as they swam nearby,
Suddenly he heard an older woman in the distance yell "Frick!" his gold eyes looked behind him just in time to see a huge wave slam in to him the short male gagged as water filled his lungs as he tried desperately to swim to the surface only to get pulled back by the current the last thing Nishinoya saw before blacking out was fallow haired girl and with gray blue eyes reaching out to him "...A mermaid?.."

when Yuu woke up he was in a hospital bed with his mother sitting by him sobbing and yelling for a doctor, after checking him over the doctor gave him the okay to leave but, not before asking it the black haired teen had any questions which he did "Y-yeah what happened to the mer- uh girl who saved me?"

both the doctor and his mother stared at Yuu oddly "What girl?" his mother asked he gave them a description but his mother shook her head "there was no girl like that when I arrived, are you sure you weren't just dreaming?" she suggested Yuu bit the inside of his cheek; he was sure he wasn't dreaming! but, not wanting to worry his mother anymore then he has,.. he kept silent about it and put the whole event put behind him.

that was until the following school year received an unexpected visitor.

"Aw crap, I'm late! the teacher's gonna kill me!" Yuu yelled running to school he had a dream about the time he almost drowned and slept through his alarm. in his haste to get to his destination the libero failed to notice he dropped his student ID or the fallow haired girl pulling a suitcase behind her.

She picked it up and went to alert the teen he dropped something but, he was already gone the long haired girl's gray-blue eyes scanned ID and was silent when she read the school name "...Karasuno" she mumbled before calmly walking in the direction the boy ran off in.
