Mai/Third Person POV-

Mai stretched, after 3 long hours and a numb right hand her paperwork was finally finished. The only problem was that now she had to get her papers signed by her big brother, Komui. Even though she was his adorable little sister he still piled her with mounds of work.

She groaned and gathered her mountain of papers that were almost her size...which wasn't much. For a girl that was about to be 15, she stood at a sad height of about 5'2, almost 5'3.

Mai sighed as she had feared there was a long line of her co-workers along with Reever, their section leader, nagging for Komui to do his work. Komui spotted her instantly, "Mai! How's my baby sister?"

Mai muttered crankily, "Wishing her brother got his work done so she could take a nap."

Komui was about to say something when Allen entered the room with Lenalee and a girl Mai had never seen before with dark purple hair. She looked about her age, slightly older and about an inch taller. She was wearing the exorcist uniform so she must've been a new accommodator she hadn't got aquatinted with.

Komui instantly leapt to his sister's side, "Lenalee! Welcome home!"

Mai made scowled as she watched the loving exchange bitterly. Why did Komui always pay more attention to Lenalee? She was only younger than Lenalee by about a year, so why does Lenalee get more affection?

Allen avoided the usual mess on the floor and told Komui, "We returned from first our mission with Nina and successfully acquired the Innocence."

Komui nodded enthusiastically, "Ah, yes. Nina just became an exorcist after all. How did it go?"

She opened her mouth to reply, but then the Innocence in Allen's hand started to vibrate and glow. Nina looked at it and stuttered, "W-what's going on? Why is it doing that?"

Komui pushed up his glasses, "Seems like we have an accommodator in this room."

Lenalee gazed at it curiously, "What? But…who else would it be? Nina, Allen-kun and I are already accommodators. And you and Mai can't be…"

Like it couldn't contain itself anymore it flew from Allen's hand straight towards Mai which startled her and made her fall, losing all her papers.

Mai blushed a deep red. She had made a fool of herself right in front of Allen...

She then noticed the Innocence clasped in her hand. She opened it and found it glowing a bright green, the vibration from it was warm and comforting, like a beat of a hummingbird's wings.

Mai stared at it in awe knowing full well what this meant, "...Me?"

Lenalee ran to her younger sister, "Mai!"

Mai still seemed shaken, "I'm an...exorcist?"

Komui came to her side as well while Allen helpfully scooped up her scattered papers and Nina stood around awkwardly.

Komui placed his hand on her shoulder and spoke to her seriously, "It seems that you are also an accommodator, Mai."

Her comrades seemed shocked. Johnny stated, "But she's a scientist! She's one of the best!"

"Well now she's an exorcist." Komui stated calmly.

Mai touched it tenderly, "It's mine?"

Suddenly when she touched it a lightning bolt shot out and hit Reever's stack of paper setting them on fire. He dropped them, "Fire!"

He ran for the fire extinguisher but then the fire spread quickly from paper to paper Komui had carelessly scattered on the floor. Mai hurriedly torn down her brother's curtains and threw them atop the fire and patted it out until it went out. All those months of hard work, blood, sweat and tears was reduced to ashes on the floor. Mai bowed, "I'm sorry!"

Reever unaware that the fire went out yet sprayed her with the foam. Mai wiped the foam from her face and Komui raced over to her and picked her up, "My poor little girl!"

Mai blushed embarrassedly, "Brother! I'm fine! Put me down!"

Komui hugged her tighter, "No!"

Mai rolled her eyes but hugged her brother, secretly loving his attention. Then he proclaimed, "I shall carry you to your room!"

With that, the sibling duo was off leaving the scientists to cry after their lazy chief, "Chief! We're months behind schedule now! Come back!"

Nina shifted nervously and glanced over at Allen, "Is it always like this?"

Allen smiled friendly at her, "Actually I'm surprised it wasn't worse."
