Hello, as this seems be a rare ship I wanted to give it a try. I think it turned out better than I hoped.

Chapter 1

Nio looked at her tablet so this was the Class Black she would be arbitrating. They seemed interesting though nobody struck her has remarkable that is until she came to a picture of a girl with short blue hair and a sharp expressionless dagger like face. But it wasn't this that had struck her instead it was the cold piercing sapphire blue eyes that stared out. Nio had only ever seen eyes like that on the chairwomen when she was focused on her work. Azuma Tokaku was the name beside the picture, interesting Nio though she found herself looking forward to meeting this Azuma.

She like everyone else had been surprised when Haru gave out here phone strap presents. Although Tokaku didn't seem to care one way or the other; the picture certainly hadn't exaggerated her look if nothing else her eyes were even more piercing in person as if they could bore though whatever they looked at. Nio found them fascinating.

"Hey I'll be your lackey" Nio had managed to catch up to the girl and had made her rather forward offer. Knowing what she did she didn't expect Tokaku would agree but she found herself hope, it might allow her to get to know Tokaku better.

"You stink" she replied, the one answer Nio hadn't expected.

Tokaku was already disgusted, she knew nothing about her target and she most certainly did want to be in this class. Everybody save Haru had the smell of an assassin including this blond girl, although Nio's scent was slightly different, more intense. There was something familiar about it she couldn't quite describe.

Recovering from this Nio decided to comment on the strap. Even though she knew who Haru was it wasn't time to revel that yet. "I don't need this" she said as she tossed it out the window and was surprised at how quickly Tokaku grabbed it. She had fast reflexed Nio though, this was somebody not to be underestimated.

As it turned out Tokaku was placed with Haru, Nio was excited to look in on them but when she checked the cameras nothing came up. The cameras were either covered or disabled, that was quick she thought, she'd already figured that the smart ones would do this but still she felt strangely disappointed not be able to look in on Tokaku.

Nio beamed, tonight was the night, time to tell everyone who the target was. She was willing to lay down money that the one to win would be Tokaku. Still she was concerned that Tokaku hadn't arrived yet. She hadn't gotten the opportunity to tell her directly about the meeting but had left a note. So when Tokaku finally showed up Nio was relieved and skipped over to give the challenge card saying "here's yours" and was going to say more only to be struck dumb (a rare thing for her) as Tokaku began to rip up the card.

What!? Nio thought, no it couldn't be, not Tokaku surely Haru hadn't; Tokaku you idiot!

Things heated up quickly after that and the psychopath Otoya's chance had come and gone; now Koko was giving it a try. Nio watch on the screen as an explosion went off in the library a feeling of concern washing over her as Tokaku used her body to shield Haru.

Concern?

What was this?

The only person who's safety Nio could ever remember being concerned about was the chairwoman Yuri. Shaking her head, she tried to dismiss the thought that she was starting to care about Tokaku's safety as well.

Tokaku stepped into the cafeteria Haru had already run ahead and now a line had formed she would have to wait. Looking around she saw Nio beside Haru at a table talking excitedly. For some reason this sight irritated her. So far she'd gotten used to the school routine and even Nio's constant attempts to banter with her and Haru. Still when she thought about it the only person to talk to her other than Haru was Nio everybody else kept their distance. Grabbing her tray she moved toward the table were the two were still engaged in conversation. She was still unsure why she didn't like seeing Nio so close to Haru. Certainly Haru was a better conversationalist than her and she was confident that Nio wasn't going to attack her, certainly not out in the open.

Jealousy?

No. Tokaku shoved that thought aside she was just being protective as she grab a chair interposing herself between the two.

Despite having her conversation broken Nio wasn't angry at Tokaku she'd gotten used to and even found enduring her rather abrasive and direct manners. She actually felt happy that Tokaku even let her sit beside her rather than try and run her off or move elsewhere as the others did.

Staring down at Tokaku's tray she laughed "curry again".

"Melon buns again". Tokaku retorted back looking at her tray.

Nio smiled she had found it endlessly amusing that Tokaku also shared a fetish for a certain food. And well Myojo melon buns were the best! She wouldn't have said the same for the curry, yet Tokaku without fail always ordered the same thing, despite Nio and Haru prodding to try anything else on the menu.

Incredibly sensei came up with the idea on his own that class black should host a play. More incredibly still was Shiena's immediate request to be made director. Shiena assigned each of them their roles and Nio found she was to play the friar and Tokaku along with Haru were to play Tybalt and Mercutio. This However meant that there'd be absolutely no interaction between her and Tokaku on stage.

Nio came up to Shiena's desk "you know maybe I should play Marcutio, I have more of the personality". "No, it has to be them" Shiena forcefully replied. This puzzled Nio was Shiena planning something.

"Still" Nio tried again.

"NO" Shiena sharply replied, glaring at Nio and ending the conversation.

Shiena wasn't the only one Nio had to worry about Haruki had turned in her challenge card. And well Nio was sure that Tokaku could take her in a fight despite her strength Haruki's last request about receiving her prize even if she were dead had her worried. This worry proved to be well founded as she observed on camera Haruki setting up the theater ceiling to fall. Even Tokaku probably wouldn't be able to survive that. She wasn't supposed to interfere in the assassinations only observe, the chairwoman would be mad if she did but still it seemed unfair for Tokaku. Maybe if she moved that prop over a bit it would provide a shield If Tokaku was smart she could use that.

Tokaku was irked she'd survived another attempt but with the stage needing repair and Shiena's exhausting re-rehearsals every one even Nio was being kept busy. She had expected that not being pestered by Nio would make her happy. Instead she kept expecting to hear that playful voice where ever she went. She'd even gotten used to Nio's scent.
