31 October is always Niou Masaharu's favorite day in the year except for his birthday. Because to him, that day means a day of mischief to others other than himself.
He press the door bell of a house, causing it to ring while waiting for person he was waiting for to open the door, soon, the door opened and appears Ryuuzaki Sakuno, one of the member of Seigaku Girls Tennis Club.
Niou first known about her was during summer holidays. The Girls Tennis Team of Rikkai was having a match with Seigaku's Girls Tennis Team, one of Niou's friends was playing in it so Niou went there to tease her rather than cheer for her... and Sakuno, as the member of Girls Tennis Club, will be here cheering.
Back to Sakuno opened the door and saw Niou. She blink. Why is Niou Masaharu here, in tokyo when he was living in Kanagawa? "Niou-san, why are you here?" she asks, for her being too innocent (or naive), she doesn't know that she should stay out of trickster if she doesn't want to be into trouble.
"Sakuno, trick or treat?"
"Eh? Gomen... I don't really understand what you mean..."
"You forgot?" Niou said with shock, although he wasn't shock at all. "Today is Halloween... so, trick or treat?"
"But... I don't have any sweets with me right now..." Sakuno said softly, if she remembers about Halloween, she would have at least prepared some sweets.
"You gotta be kidding... coz' I saw such a sweet 'sweet' in front of me." he smirked his usual smirk and come closer to her.
"But I'm sure I don't have any sweets with me!"
"Are you sure?" he says in a seductive tone and slowly place his hands around her waist, giving her no space to escape. He pushes her into his arms, "But aren't a such a big sweet?"
"Niou-san!"
"I can't wait to taste the sweetness within you..."
Owari.
