Re:ZERO -Starting Life in Another World- S00 E13 Re:PETIT ~Starting Life in Another World From PETIT~ 2: Beatrice, Self-Proclaimed Teacher

"Racing through the journey of memories——"

Subaru is shocked to find that he is in the same class as Felt, and even more surprised to discover that their teacher is Beatrice. When he expresses his disbelief that someone who looks so much like a child could be a teacher, she tickles him. He tells her that he thought she was going to suck his mana out, and both her and Felt mishear him as saying “mayo.”
