/Hello! Ok, so I'm writing this story with Tantei-Otaku-Kun. Her OC is Serenity, while mine OC is Miyu. I hope you will enjoy our story!/
"Father, you cannot be serious!" A certain young warrior yelled furiously. She have a shoulder-length white hair, a part of her hair tied into a single bun. She is wearing a white shirt with a jacket that has a crescent moon on the back of the jacket. For the pant she wears a black jeans. "You cannot possibly just leave me there's in Paris for kami's sake! Why you just sent guards to investigate it instead?" She demanded angrily.
Her father give a cold look.
"How dare you ranting on me for being so foolish?" He said coldly. "You're a warrior that I raise you for the past thirteen years!"
She winced and felt guilty that she ranted her own father, for being stupid.
"I'm sorry father. It won't happened again." She apologized. "Again. May I know why that your sending me to investigate to Paris to just confirm that stupid, Hawkmoth, is there?"
He nodded seriously.
"Of course. Please have a seat." He said and point the chair. As she sat down, his face become deadly serious like he is going to one of the hell war. "There have been rumors about Hawkmoth appeared, and he was last was seen sixteen years ago. There was a two thief that stole the prehistoric Miraculous and burned out the ancient temple's people. Fortunately there's only one that have survived the attack and took the ancient box that held two legendary Miraculous, Ladybug and Chat Noir..." He bit his lip in concern/worried. "Those two legendary Miraculous haven't been seen for several centuries for Tsukino heir...However ever since a year ago Ladybug and Chat Noir appeared since Hawkmoth made his first move to get the legendary Miraculous. And you see why that I'm sending you there to help and guards Ladybug and Chat Noir with your life even if you need to use your forbidden spell, remember Serenity Lunar Tsukino, use that spell when the time is right."
Serenity nodded in determination.
"Yes father. I will obey your wishes. I, Serenity Lunar Tsukino will forever help and guards my master within my life." She vowed. Once that vowed begins; it won't be broken until the day she die.
"I wish you a great luck my lady." The maid smiled softly and then warned her. "Please don't use that forbidden spell, I don't want to see the last heir of Tsukino bloodline. We need you for the sake of the Kingdom of Lunar, it will fall into ruins without a heir."
She chuckled nervously, facing her wrath is scary.
"No promises." She joked.
She glared at her and then sighed.
"I raised you for sixteen years, you are like my unborn child that unfortunately died at birth." She said sadly.
She look at her sadly.
"But I'm your 'daughter-figure', I don't mind that you call me daughter." She smiled kind-heartedly. "Be a frank, I don't like you when you say 'my lady' it sound like I'm in trouble..."
"Nonsense, I need to give you respect!" She said sternly.
Serenity rolled her eyes.
'Typical...' She thought. 'Worth a try I guess.'
"SERENITY LUNAR TSUKINO!" Her father shouted. "IT'S TIME TO GO!"
"Crap! Bye!" She yelped and waved for a farewell at the maid. She rushed out the room with her stuff in the sliver packing-bag.
By the time she got down stairs, her father give a stern look.
"Your late Serenity." He give a cold look.
She cringed at his tone.
"Sorry father." She apologized. "It won't happen again."
"I certainly hope not." He muttered.
She give a you-don't-know look.
"Don't jinx it."
"Too late."
She groaned. She is not looking forward to go to Paris to face-to-face that stupid, Hawkmoth.She give her packing-bag to the servant to put her packing-bag in the trunk.
"Anyway I apply you to school that called 'Françoise Dupont High School' in Paris."He said coolly.
She stunned in shock because she have never went to school in her life; she was home schooled in her life.
"EEEH?!" She yelled in shock. "Me? Going to school?!"
He nodded grimly.
"Yes. I have suspicions that Ladybug and Chat Noir secret identity lies there." He said.
"Uh, so, they're teenagers?" She asked.
"What? I got my Miraculous when I was your age." He defended the unknown holder of two legendary Miraculous.
She snorted.
"So, I'mma to school being a princess?" She asked sarcastically.
He grimaced.
Serenity's eyes widened.
"Oh s—!" She choked. "You gotta be kidding!"
"Sorry." He said quickly.
She groaned; not looking forward to Paris AT all.
