Yu-Gi-Oh! Dark Side Of Friendship

After the story, the bell rang and the girls went to each of their classes. Yugi started to walk around the school, when he was busted by a teacher. He looks at a much older girl who as purple and pink hair and green eyes.

She asks "Do you have a schedule."

He replies with "No, but..."

she cuts him off with "are you new here?"
before he answers, she cuts him off again by saying "follow me, and I'll get you a schedule and show you around."

Yugi nods his head in approval. He follows the older girl to some office where a much older lady awaits. She looks at him and says "I'm principal Celestia, how can I help you?"

A few mins later (like 30 or 45 mins.) Principal Celestia walks into a classroom with a short kid saying "Everyone, this is our newest student. All of you make sure he feels right at home." Then she leaves.
