She was the only one who could distract him, upset him, throw him off balance, so for that he was wary and distanced himself from her.
But she was the only one he could laugh with, share something approaching a conversation with, and enjoy sharing his presence with. For that he loved her. Yes Hibari Kyoya was in love.
But she's full of secrets, ones even she, herself is unaware of.

Day 5

A gust of wind announced her arrival.
Hibari quickly closed the reports he was reading and slid them under a stack of paper. "Hello Hibari Kyoya" the girl crouched behind him said as she balanced on the back of his chair.
"Hi" Hibari replied not turning round. "Ready for our game of Shogi*" she asked as she leaned over and held up the board game in front of his face. Hibari cleared his desk (making sure the reports he was reading were hidden, not that they had anything on her) and then pointed to the chair that was seated opposite him, sat on the other side of the table

The girl leapt up and sailed through the air above him, giving Hibari an interesting view of her bum, twisted round and landed neatly into her seat, her legs criss-crossed and her two fans in her right hand. She splayed them open and started fanning, "Let's start"

It was the 5th day of Hibari knowing the girl and her 4th visit. The girl would visit briefly and shortly, appearing then disappearing quickly with gusts of wind the only evidence she was ever there.

Day 3 had been hard; the girl had visited him to practically just torment him. Her sly taunts and her over- whelming smugness that she knew about him whilst he knew nothing about her infuriated him and Hibari would have bitten her to death if he hadn't known that such a reaction was what the girl had wanted so he denied her that triumph. Hibari had redoubled his efforts to find some information on her but still nothing. There were many patients to the hospital that day

Day 4 was when she brought the Shogi board game with her. It turned out that despite her playful teasing side she wasn't much one for conversations saying that yappiting on random topics bored her. Hibari quickly realised that as well strong she was smart, and a very rewarding opponent. It was Day 5 and she had brought the Shogi board with again, planning to continue their unfinished game from last time, having memorized all the pieces positions, not that she wouldn't try to pull a fast one on Hibari to get her pieces into better positions which was why Hibari also memorized the positions.

Hibari moved his kakugyō* forward 5 spaces in a diagonally right direction and leaned back smirking not bothering to even keep up his poker face. This game was almost over, one more move from him and then it would be checkmate on the next turn and there was nothing the girl could do. But instead the girl just leaned forward smiling. Hibari's eyes narrowed, this girl was up to something. The girl had one arm up straight on the table and she slowly leaned forward, her kimono stretching giving Hibari an aerial view of her breasts. Was she trying to distract him, so that she could pull a fast one on him? Hibari glared at her, showing that he wasn't fooled but still the girl leaned over inch by inch bringing up her other arm to the table.

Then came a knock on the door and the girl was gone a slight breeze filling the room.
It was one of his minor subordinates, not even one he that one that was on his special project, blabbering on about something that was of little consequence so Hibari wasn't listening, focusing on the Shogi board, a development that had occurred in the last second.

The girl had returned a captured piece back on the board, a piece from yesterday, a piece Hibari had completely forgotten about so focused was he one carrying out his moves. The girl had placed it in the perfect place. She had placed it to put his King under check leaving Hibari with two choices: he could either go move his kakugyō to get his King out of check or continue his attack and have his king checkmated meaning game over and she's won.

It left a subtle but loud message: Back off or your King gets it.

Hibari inwardly smiled, this game was far from over. Then he turned his attention to his subordinate. "I'll leave you in charge of the situation take whatever actions you deem necessary that's all" and he dismissed the subordinate who scuttled out amazed that he had been such power so quickly.

Hibari then took up the reports which pertained to his special project and looked over them again.
Another game was being played with the same opponent.
