Gai Sensei
A teacher who thinks he’s the best, and also a guy named Fuad Kabir who probably thinks he’s the best too. They both like being called sensei, even though they’re both a little weird.
Fuad Kabir showed up in the middle of a battle and said he was the real sensei. No one believed him.
He tried to teach Lee how to do the renge. It ended in tears and a lot of screaming.
He and Gai had a friendly rivalry, but it was more like a middle schooler’s crush.
