Kaku had been having a boring day at the Enies Lobby, and with Jyabura constantly making fun of him today for some odd reason, it didn't make things any better as he decided to just lock himself into the library for a while. Storming inside and slamming the door shut, he peered through the keyhole to make sure no one had followed him, and sighed in relief as he saw no one, only to turn around and find the ugly, grinning face of Jyabura in front of him. He gave off a shrill squeal of fear as he pressed his back against the door, but then just 'hmph'ed as he saw who it was. "Why won't you leave me alone, old-timer?" he sneered.

"You tell me, Square Nose, I was here first." Jyabura smirked as he pressed his finger against Kaku's nose as the swordsman gave of a yelp of pain, as he followed by rubbing his sore nose. "Hah! Sensitive as always, Kaku. Geez, you're such a girl."

"Shut up, ol' fart!" Kaku growled and pushed the old man aside as he walked deeper into the library, and Jyabura merely stroke along one of his elongated mustache strings before he followed the younger man, who of course was annoyed. "Do you have any better thing to do than to follow me?" he snapped at Jyabura.

"Heh, 'fraid not." Jyabura grinned a bit as he pushed Kaku onto one of the bookshelves, and the younger man grunted in slight pain. A book fell out of the shelf and opened up in front of them, and none of them noticed the mysterious patterns and signs in it. "Geez, you're such a girl again, Kaku." The elder man teased, but suddenly, a bright flash erupted from the book, and blinded both of them. "Damn! What the hell was that?" Jyabura grunted as he rubbed his eyes, but as he opened them, he was shocked. In front of him was still Kaku, but his body was slightly more slender, and two visible mounds stuck out of his – or her – shirt. "W-What the hell happened?"

"What you talking about Jyabura… wait… is that…!" Kaku noted his voice was a bit brighter, and as he looked down at himself, he shrieked, seeing he was now a she. A girl. "W-What the hell happened!" he demanded, trying to cover up her newly-discovered breasts, but Jyabura just grinned.

"Well whaddya know. You were such a girl, you got turned into one!" he smirked.

"I-I think it was the book." She replied. "I-It turned me female. Please tell me there's a way to turn me back to male!" Jyabura picked it up and read through it quickly, skimming through the pages until he stopped, and read one part. "W-Well?" Kaku asked again.

"Yep. There's a cure spell." He said, and Kaku sighed in relief. "But…" he slammed it shut, putting it aside as he grabbed Kaku and pushed her to the wall. "No reason to take advantage of this moment, is there?" he grinned, groping over Kaku's newly-formed breasts, which made her moan a bit. "Heh, knew they weren't fake." He smirked, and before Kaku could protest, the elder man mashed his lips against Kaku's, and the two of them kissed each other while both of them began moaning in delight. Jyabura's tongue swirled inside Kaku's mouth and met with hers, and they both turned it into a deep French kiss. After a few minutes, their kiss ended, as a thin line of spit was seen between them. And as Kaku looked down, he saw he had turned back to a man.

"W-What the…" he looked up at Jyabura again, who grinned a bit.

"Well, the spell said that the one cursed by the "Gender Spell" had to get a kiss to turn back. But he/she had to enjoy it as well." He growled slightly, being part wolf thanks to his Zoan fruit. "And I can see you enjoyed it…" Kaku looked down and blushed sharply, before he ran out of the library, hands covering a new bulge in his clothing… much, much lower this time.
