Chapter Nine

"You know," Kamui began conversationally, "Your tree is talking to me."

Annoyed Seishirou faced the shorter male, It was bad enough having to spend the whole day 'bonding' with his supposed brother but now he had to talk to him too "How charming- wait the tree can talk?!"

Kamui smirked content in the knowledge that he knew something the great Suakurazukamori didn't about his own tree. Seishirou bit his tongue for allowing his ignorance to slip. Kamui would use it against him for sure but it was too late now to pretend he knew about the damn things supposed voice.

"So you've been serving this tree for how long? And it hasn't talked to you," Kamui began laughing and Seishirou frowned "Not that I can blame her of course."

"If it chooses to speak to you brat, I think I'm better off," Seishirou said nonchalantly

The stupid tree, who in their right mind would choose to talk to Kamui? And why not him! He was double the man Kamui was – at least in height anyway. Kamui was probably lying through his teeth – the damn brat. He'd call his bluff!

"I guess your mind must be just as primitive as the tree's then," Seishirou retorted.

Trying his best to ignore Kamui's smug face as to avoid the suspicion that he was curious, Seishirou asked in flattest tone possible, "What does my tree say anyway?"

"Oh I didn't think you'd be interested Sakurazuka-san?"

"Of course of not dear brother, but why not indulge me?" Seishirou said smiling sweetly.

For some reason, perhaps because there was a brain beneath all of Kamui's hair, he decided to quit provoking the man.

"She says she wants a new assassin... You're becoming quite inconsistent."

How dare 'she'. He was good at his job!

"Also that you should hurry up and just kill that damn – oh my God not Subaru!"

"After all she has no intention of starving to death... it's nothing personal... well... nevermind..."

He was sure he could do with firewood. Serving a tree all his life... Why did he have to be like every other assassin in his family anyway? He'd always been rather inclined to change. Thinking about it he'd always thought about growing a moustache... well that was slightly too much change for him... maybe a beard or no... Maybe he'd just not shave for a day! Some people liked a bit of stubble on a man... maybe Subaru-kun...

Seishirou noticed that for once Kamui was actually quiet with an obvious blush tinting his cheeks. Staring at him pointedly Seishirou sighed, "What did it say?"

When Kamui started stuttering, Seishirou was very pleased he had reduced himself into asking.

"Uh...W-w-well uh she has other suggestions for what you could do to Subaru-kun. Not that I'll let you of course," Kamui finished haughtily despite his rather unfortunate mumbling. It did not appear as if he was going to tell either.

"Also that if he dares to kill you she'll torment you for all eternity because there is no way she is belonging to –Your tree is evil Seishirou. Really you have got nothing on her!"

The assassin was slightly disturbed at the news that Subaru would want to kill him. He'd thought they'd been through all of that already. Did his Subaru-kun still hold a grudge against him? Besides he'd make an awful assassin. Even Kamui made a better assassin than him – and that was saying something...

"Ewwwe Subaru-kun with you!"

Seishirou really wished he'd been more obedient as a child. For then he might have remembered the skill of selective hearing. If only he could control his hearing enough to completely block out the odd frequency of Kamui's voice! Assassins were not supposed to have brothers or any siblings for that matter; not even any family! His mother killed his father. He killed his mother and if he didn't do something about Kamui quickly the boy would kill him. He certainly seemed insane enough...

Kamui furrowed his brow and Seishirou assumed he was trying to speak back to the tree. He would never admit to himself but he knew the feeling inside was jealousy; stinging irrational jealousy. He had no desire to talk to the tree but the fact that Kamui could and he couldn't! Their brains must be truly primitive and therefore compatible Seishirou rationalised. Maybe he should kill Kamui... but then everybody would be suspicious. They knew he'd hardly taken the news that they were siblings well. No... He'd buy time and when he was back in the clear he'd make his move on Kamui. It would be an accident of course but...

Kamui rudely interrupted his reverie by shouting excitedly, "I..."

It was at this moment that his vision faded slowly till he looked around at empty white space. The last thing he saw was the swish of long blonde hair and pale fingers as the figure fled.

Opening his eyes Seishirou found himself snugly wrapped up on his couch a shrill ring reaching his ears. Throwing what must have been the weirdest dream of his life to the back of his brain he attempted to get up to answer the phone only to see two bright eyes in front of him.

"Finally you're up Sei-san!" Hokuto screamed joyfully with a much deserved mischievous glint in her eyes.

Seishirou just stared at her blankly for a few moments... Why was he not in bed? Who had tucked him in with a blanket and just why was Hokuto-chan in his apartment? The twins had never come to his apartment had they? Well he couldn't remember now... come to think of it he wasn't sure they knew where it was... but most importantly how did she get in?

Smiling brightly Seishirou said, "Hello Hokuto-chan!"

Hokuto, who already knew what a great actor her future brother in law was, was not in the least bit surprised by the cheery greeting.

"Ah you must be so hungry Sei-san! I've made a wonderful breakfast for us though and I have so much to tell you!" She said scurrying off into his kitchen. He noticed there was a black tail protruding from her apron and two pointed ears protruding from her head. They bounced from side to side as she ran and he suppressed a much needed laugh.

"Hokuto-chan what are you doing in my-" he started rising from the couch and making his way into his kitchen. He knew not what Hokuto was playing at and for some reason that really scared him. Though nine times out of ten he wasn't positive he knew what the girl was thinking.

"Oh... there you are Sei-san! Hurry, eat before it gets cold and I'll tell you everything. I need to get to school now anyway..."

Reluctantly and impatiently Seishirou sat awaiting an explanation. He didn't have to wait very long for words to flutter from the girl's mouth.

"You have reservations at Jasper's Restaurant tonight at eight pm. It's a very good choice you know it specialises in western food though you can get dishes from all over the world," She paused.

Seishirou looked at her like she'd just literally grew ears and he wondered if he'd entered a new space-time continuum.

"Of course, you already sent a letter to Subaru-kun asking him on the date-"

"-I did?" Seishirou confusedly interrupted.

"-Go you Sei-chan! You'll be happy to know he accepted and he'll see you at eight tonight!"

"But-"

"I'm so happy you've finally started to take this relationship seriously! I would have resorted to serious actions, believe me you would not guess the plans I had for you guys... I really would like to stay and chat but I can't be late to school. See you later Sei-san and I'm sure you'll love the outfit he'll be wearing!"

With his mouth agape Seishirou heard the front door of the apartment swing shut and as if his luck wasn't already bad he heard another person enter the apartment. On his guard he made his way to the front room where Kamui was already standing.

"I was going to knock but Hokuto-chan assured me you wouldn't mind if I just went in Sakurazuka-san. Though it did seem you really were not expecting visitors," Kamui said quietly, his gaze turning to the blanket on the couch, the distinct lack of house slippers and Seishirou's own disgruntled appearance.

Slightly shocked by Kamui's politeness but eager to find out what he wanted Seishirou invited him to sit down, offering food and drink which was politely declined. It was well with the assassin seeing as he doubted any food was left after Hokuto's extravagant breakfast.

"I do hope your wrist is better now Kamui-kun?" he asked a bit surprised that it wasn't bandaged after the damage he had done to it last night. Taking a good inspection of the boy, Seishirou was happy to find that he saw little to no resemblance in himself. Still, he could not have been mistaken about the dream he had. It was not one to be dismissed lightly. Not at all.

Kamui looked at him dazedly then seemed to remember, frowning he said, "Yes. Thank you."

He sounded strangely devoid of all sarcasm.

They sat for some time in silence; Kamui distractedly digging his fingernails into his thighs and Seishirou studying him dangerously. He knew what was coming.

"You want to tell me something Kamui-kun. By all means go ahead. I'd hate for you to be late for school. Your education is very important after all."

Kamui caught his eyes. No words passed only a deep questioning between the two.

"I received a letter today. It was a reminder that I had a reservation at Jasper Restaurant."

Interested, Seishirou raised his eyebrow, "You did?" It was very odd indeed. He had immediately suspected Kamui or at least Hokuto to have made his and Subaru's reservations... but it was slightly uncanny for Kamui to be in possession of one too.

"You mean it's not from you?" Kamui mumbled thoughtfully "I thought you'd want to pay me back for yesterday or something... And Subaru got one too written from you and the writing was identical..."

For a moment Seishirou looked confused then his expression changed to that of a person who had just remembered something, "Ah yes... I did book a reservation for Subaru-kun and myself a few months ago. Jasper's is always so busy you have to book far in advance" Quietly he mumbles to himself, "I must be getting old, I'd quite forgotten." It was almost purposely said.

At that Kamui smirked but remained silent. A few moments passed before he spoke again.

"Well I guess I don't know who I'm meeting then, "Kamui said flippantly. Then with his lips slightly tilting upwards and a look of consideration on his face he said, "I doubt even you could handle two teenage boys right Sakurazuka-san."

Refusing to be provoked Seishirou answered just as flippantly as Kamui, "My heart is for Subaru-kun alone... I'm sorry Kamui-kun if you thought I or if you have feel-"

Kamui chose that moment to cough indignantly at what the older man implied.

"I didn't think that," he said plainly though his cheeks were still red from the accusation.

Pleased that he'd now embarrassed Kamui enough and restored his pride Seishirou had to find a way to get the young teenager out of his home. He was so concentrated in thought he almost missed when Kamui stood and began to move to the apartment door.

"Oh and one more thing Sakurazuka-san," Kamui started.

"I know." With that Kamui left.

Seishirou decided he needed to move apartments and buy a few more locks.
