Real name unknown. Civilians or those outside the organization call him "Elder," while Mido's private soldiers simply call him Kagemusha. A Japanese man in his 50s or 60s acting as a body double for Mido Kosaku. His actions seem evil, but in reality, he doesn't even come close to the true Mido Kosaku's cruelty. He has a surprisingly youthful physique and fair skin. There are moles on the left side of his neck and under his eye, though it's unclear if they are real or drawn on. Most people (except the assassins) believe he is the real Mido.
