"Im gonna be late again !" Serenity cried, running to school, her black hair blowing in the wind behind her. It was days like this when she hated being half-demon and couldnt run at top speed. She finally reached school and proudly stepped into her classroom.

"A new student ? Nice you meet you, young man" the teacher said. Serenity sweat-dropped and laughed a bit. "Im Serenity ! But thanks for the complement !" Serenity said with a grin.

(Later that day)

Inu-yasha and Serenity were training in the backyard more than ever. "Come on Serenity, you can't be tired yet !" Inu-yasha shouted. "Me tired, not a chance !" Serenity shouted as she ran at Inu-yasha at full speed. Inu-yasha began running at her as well. They both jumped into the air to kick one another.

Inu-yasha kicked Serenity in the center of her face and saw her drop to the ground, rubbing her face. "No fair ! Your legs are longer than mine !" Serenity cried. "That's why im glad you're a girl, if you're a boy, that would've been a perfect kick to my face !" Inu-yasha laughed. "A boy ? Hmm..." Serenity muttered to herself.

(The next day in China)

"So, you said you wanted to train ?" Sesshomaru asked. "Yeah, I want to be able to beat Inu-yasha for once" Serenity said. "Did we really have to come to China to train ?" he asked, crossing his arms. "Well, no...But I wanna try something" Serenity said.

"You wouldn't even be here if it weren't for me, I had to swim here with you on my back !" Sesshomaru growled, placing his hand on Serenity's head and cracking her neck a bit. "I'm sorry Fluffy-sama ! Stop trying to internally decapitate me !" Serenity cried. "Let's just go to this training ground" Sesshomaru growled.

After finding the training ground Sesshomaru and Serenity jumped on different bamboo poles. "If I fall in, im blaming you" Sesshomaru said. "You won't fall, you're an expert" Serenity said. "What a true fact, now attack me !" he shouted. Serenity jumped at him and aimed a punch. Sesshomaru blocked her attack and knocked her away.

"EEEEK !" Serenity cried as she quickly clung to one of the poles. Sesshomaru shook his head and kicked Serenity off the pole and into the air. "Hmm ? I had no idea she was that light..." he thought. When she came back down she landed right into a spring. "Help ! I can't swim !" Serenity shouted. Sesshomaru jumped in after her, forgetting what kind of water it was.

Serenity watched her vision become blurred by the water. Horrible thoughts of her drowning raced through her mind. She was then pulled out of the water and held close to Sesshomaru. "You okay ?" he asked.

"Yeah, just great" Serenity said, coughing up water. Something then caught her attention, why didn't Sesshomaru change ? Did they fall into a normal spring ? "I'm so glad you're okay !" Sesshomaru said as he hugged Serenity tightly.

Sesshomaru's eyes narrowed and he hugged Serenity tighter. He felt his hands along her and felt her figure had gotten more masculine. He backed Serenity away from him and felt her chest. Flatter than day old soda.

"Serenity...you're a...a..." Sesshomaru tried to say. "A boy ?" Serenity asked. "YES ! Why ? You were supposed to be the only girl in the family !" Sesshomaru cried. Serenity rubbed his own chest and sweat-dropped. "Im a boy...it's happened...ALRIGHT !" Serenity cheered.

(That night)

"Just where have you been, young lady ?" Inu-yasha asked furiously. "n-nowhere" Serenity said. "It's late ! Have you forgotten that you are to be home no later than sunset ?" Inu-yasha growled. "No, I didn't forget. But coming back from China took longer than I thought" Serenity said. "CHINA ! You went to China !" Inu-yasha shouted, getting angrier by the second.

"Sesshomaru went with me...I thought you wouldn't mind. Plus, I had a run-in with the Cursed Springs" Serenity sighed. Inu-yasha felt Serenity's chest. "You're a boy !" he gasped. "Yep..." Serenity said.

"Anyway, I don't want you going to China ! You know what happens to girls there !" Inu-yasha yelled. "I can take care of myself, Inu-yasha ! Im not stupid like you !" Serenity yelled. He then gasped, had he just said that ?

Inu-yasha grabbed his wrist and dragged him to a chair. "So...I'm stupid ?" he asked, holding back his rage. "No ! You're not stupid ! You're the smartest person I know !" Serenity cried. "Im not falling for that, even though it is true" Inu-yasha shouted, sitting down and yanking Serenity over his lap.

"Please no Inu-yasha !" Serenity begged, which sounded different with her now being a boy and all. Sesshomaru sighed and covered his ears, knowing the wailing would soon come. Serenity closed his eyes and cringed, waiting for it to begin.

The familiar sounds of someone getting spanked were heard, but no screaming was heard. Serenity opened his eyes and actually grinned. This wasn't hurting all that much. "Is that all you got ? Man you must be getting weak !" Serenity laughed.

Inu-yasha stopped smacking him and blinked. "You don't feel that ? You some kinda masochist or something ?" he asked. "No ! Im not like your pink-haired girlfriend !" Serenity shouted, getting off Inu-yasha's lap.

"You're off the hook this one time, but don't go to China without telling me ever again, or else !" Inu-yasha warned. Serenity shrugged then got an idea. "Inu-yasha, I've wanted to do this for a long time, but I never had the guts to !" Serenity shouted as he ran at Inu-yasha and kicked him in his crotch, hard.

Inu-yasha made a high pitched shrieking sound before dropping to his knees and onto the floor. Serenity laughed a deep voiced laugh and grinned. "This is gonna be fun" he thought.
