Kōta from Baka and Test doesn't usually have bicolored eyes, but in this part, when he's selling Hideyoshi porn, he has Lelouch eyes. :D Kōta is the one with the blue hair, BTW~!
One is kakashi Hatake from Naruto/Shippuden. I was waiting for someone to mention him also. :D Mandara Uchiha counts as one, because he took the rinnegan from Nagato.
