He can't see anything on the day and barely can see a blurry image on night. He's an assassin who works for money. He uses a sword hidden in his cane. He was a very good warrior in the samurai age, but his eyes got sick and now he can't see very much. So, no one wants to hire him. He's calm, very serious, strong, but he is clumsy and vulnerable in the day, but he denies his condition as a blind man. He doesn't speak too much. He trips with almost every single obstacle in his way all the time.
