Same jist as the previous entry.

This story will take place a couple years after the end of GX. Judai is called back to the academy, being told that he was the only one that they could contact with what was happening there. What he finds isn't a threat to the world or even a threat to the academy. IIt's just a new student who refused to leave her dorm room until someone proves to her that someone really did graduate as an Osiris student. I'll just let the preview speak for itself.

...

Preview(third person perspective)

Judai walked along the path to the Osiris dorm. He arrived to find several Osiris red students going about their daily business. Judai was a little surprised to find out that there were girls in the Osiris dorm now and that there was now an Osiris Wall of Fame with his picture on it. One of the girls saw him and ran up to him.

"Excuse me," she said, "are you really Yuki Judai-sama?"

"Yeah, I'm Yuki Judai," he responded.

"Can I have your autograph?" The girl asked, offering her duel disk.

"Uh, maybe later. I'm actually here about a student who's causing some trouble. Do you know anything about that?"

"Huh? Oh yeah. Machiko-chan locked herself up in the dorm and is telling everyone to go away."

"Machiko?" Judai asked, "Could she be that Machiko?"

Judai walked up the steps to upper dorm rooms. He twisted the door knobs until he found the locked one. He knocked on the door.

"Unless you're an Osiris graduate, go away!" A voice Judai knew answered.

"Hey Machi-Machi, is that any way to talk to people?" He called.

"Eh? Judai-nii?" The door clicked as it unlocked and Machiko peaked out. Her eyes widened at the sight of Judai. She opened the door and embraced him, "Judai-nii! I missed you so much."

"I missed you too little sis," Judai said, patting Machiko's two-tone brown hair, "but why didn't anyone tell me you were coming to Duel Academia?"

"How was anyone supposed to tell you when no one knew where you were?" She asked, "You never called. Wait, if you're here, then does that mean?"

"I'm an Osiris graduate," Judai confirmed, "why else would I be on that Wall of Fame down there?"

Machiko stepped on Judai's foot.

"That's for not calling to tell us," she said, "jeez, mom was so worried that you had dropped out."

"Sorry, I'll go and visit to tell her when I get to the city."

"Your going to call and tell her, now."

"OK, jeez. I hope your not this bossy with your Duel Monsters."
