Kyoshiro Mibu ( Mibu Kyōshirō ) is the protagonist of the Samurai Deeper Kyo series, who possesses the soul of Demon Eyes Kyo and powerful ocular prowess. He is the third Red Cross Knight created from the flesh and blood of the Former Crimson King .

The former Aka no Ou reabsorbed Kyoshiro and  Chinmei  (or Kyojiro Mibu, Kyoshiro's first brother)  into his body, to regain his strength. Inside the former Aka no Ou's body, Kyoshiro met his second brother,  Kyosaburo Mibu .

Kyoshiro, like Kyo, knew the  Mumyo Jinpuu Ryu  sword technique (he has learned this technique  to protect Sakuya). He was able to master every technique except for the Kouryuu, the ultimate attack (because he never reached/released in battle his full potential or "the Power of Faith",  see  Demon Eyes Kyo  Techniques)
