Shou Marufuji sat in solitude under the tree on the Osiris Red dorm's cliffside, remembering the good times he had with Judai Yuki, his best friend and big brother figure since his first day at Duel Academy. It had been a week since Shou and the rest of his friends had returned from the Alternate Dimension, and even though Judai said he would be back, Shou couldn't help but cry, wishing that he was there with him right now. Just then, in the sky glowed...

"A shooting star?" Shou, with his last ounce of hope, wished upon it; "Please bring Aniki back. I want to tell him one more time how I feel at this moment...!" He paused to see the shooting star descending upon him. Panicking, he dove to the ground to avoid it, but the meteor rocketed passed him, crashing to earth with a strong tremor deep in the forest.

"Is... is that...?" Shou blinked. He ran into the woods in the direction of the star, wishing, hoping beyond hope that his wish had been granted. Sprinting through the thickening trees, he approached the crash site, where smoke still emanated from the impact. As the smoke started to clear, Shou's heart leapt as he saw the profile of a person who stepped out of the crater.

"Aniki!" Shou cheered with delight.

"Shou, today was fried shrimp day, right?" Judai Yuki chuckled pleasantly.

"Aniki!" Shou cried with delight, running up to his best friend and giving him a big bear hug, overjoyed to have him back.

"Did you miss me?" Judai smiled. Shou was always a head shorter than him, but as he held his best friend, he noticed that Judai had grown a few inches since they last met. However, that wasn't the only thing about Judai that had changed since they last saw each other; for some reason, his head was pressed against something very soothingly soft...

"Mm?" He pulled his head back a small ways to see something he obliviously overlooked in his delight of Judai's return... well, two somethings... two very big somethings... "A-aniki, you're... a-a-a-a-a...!"

"A what?" Judai blinked.

"A-Aniki? Do you... feel any different?" Shou blushed, trying not to look directly at these new somethings.

"No." Judai shook his head, puzzled. "Why?"

"Uh..." Shou's joy was now turned to confusion. "Well, for one, you're... naked..."

"wha...?" Judai blushed, looking down at himself. It was then that he noticed just what it was Shou was getting so embarrassed about. "WHHAAAAAAA!?"

"Everyone! Good news." Shou announced to his friends, who were still reminiscing about the old days.

"You mean...?" Manjoume whipped around to face Shou.

"He's back, don?" Kenzan blinked.

"Well... yeah, but... there's something strange about... 'him'..." said Shou awkwardly. "Come on, I'll show you..." He led the group to the room that he used to share with Judai. The moment the door opened, Manjoume, Kenzan, and Fubuki turned very red in the face, shocked at the new Judai, Asuka simply staring in confusion.

"H-he's a... a she?" Manjoume blurted after a moment of stunned silence. Asuka flicked him in the back of the head for his tactlessness, but couldn't say she wasn't as flabbergasted as he was.

"He definitely is a girl now..." She thought, her eyes scanning Judai's new body. Though his face still maintained some of its young, boyish charm, there was something noticeably feminine about it now, his hair had grown almost down to his shoulders, and his body bore a very womanly figure, a perfect hourglass-shaped middle, very round tight butt, and large breasts about the same size as her own.

"What happened to you?" Asuka asked, unable to think for the life of her how he could have ended up like this.

"I don't know." Judai answered, trying on a few of the clothes he had laying around his room, but he had outgrown everything, even his signature red jacket. "Am I really a girl now?"

"And what a girl!" Fubuki grinned flirtatiously. Asuka dragged her older brother away by his ear as he objected, claiming that it was okay because Judai was still technically a man.

"He's made me wait all this time, and he comes back a chick?" Manjoume scowled. "Is he trying to screw with my head?"

"Aniki's an 'Aneki?'" Kenzan blinked, having no idea what to make of this situation.

"Guys, sorry, but I need some time alone." said Judai, prompting her friends to leave.

"I don't care if you're a girl or a boy, Aniki." said Shou as the others left. "To me, you'll always be my Aniki."

"I know." Judai smiled. "But I need some time to think right now. This is all really confusing."

"Alright." Shou nodded, closing the door behind him as he left.

"This is really happening..." Judai muttered to herself once her room was quiet once more. She held her breasts, feeling them to make sure they were really a part of her body. She looked down past them to her crotch, where his penis used to be. Now, there was nothing. He ran his fingers down the flat plain where his genitals used to be, as though making sure that they weren't invisible, gasping at a new sensation she felt as her fingers moved a little further down. She sat, and peered down between her legs.

Judai didn't pay much attention in sex ed class, but she knew this was the thing that girls had that boys didn't; a vagina. She ran a finger exploringly down the front of her entrance, gasping again at the sudden shot of pleasure that coursed through her body. She opened the folds of her pussy with one hand, and while taking in the sights of her new genitals, explored how each part of her new anatomy felt with the other hand. Though the feel of her vagina shocked her and made her body tense with every touch, Judai couldn't help but want to feel it more and more.

"Are you enjoying your new body?" Judai flinched, suddenly closing her legs and covering her new body as she turned to see the translucent form of her fusee, Yubel.

"Uh, I... I didn't know you were here...!" Judai stuttered.

"Just relax. It's normal for a healthy young woman to feel this way." Yubel smiled with amusement.

"But I'm not a..." Judai broke off, an idea coming to mind. "Wait, is this because of our fusion? Did fusing my body with yours make me a woman like you?"

"So it would seem..." Yubel mused, bending down and examining her fusee's new body. "I hadn't thought of that. And I never would have thought the use of Super Fusion would have had such a... drastic effect on your physical form."

"Me neither." said Judai, feeling her own breasts.

"Do you regret this fusion, then?" Yubel asked. "I wouldn't resent you if you did."

"No. Not at all." Judai assured her. "But this is a difficult thing to wrap my head around. It's definitely going to be a hard thing to adjust to..."
