Takeshi Kaga was the Japanese Chairman on Iron Chef, and was also Jean Valjean in Les Miserables, among many other things.
I only just realized they were the same person and had a little spaz attack. Hence crappy MS Paint Kaga-sensei tribute.
I love all three of these, Iron Chef, Les Mis, and Takeshi Kaga~
ETA: bluepeets has graciously informed me that in the middle picture above, it’s Kaga as Javert rather than Valjean. He’s played both parts! Meccha sugoi.
