Shin Megami Tensei II
After orchestrating an explosion in the Center, he escaped, along with Mekata, but at an unknown point, probably because of their sharply different objectives, they parted ways. Hanada then started to work under the Madam's, being responsible for summoning demons that were used in the Coliseum to do battle. Feeling that the perfection of his research was being restrained by this, he escapes once again, now to the slums of Valhalla, where he planned to open a portal to the Abyss. After Aleph and Hiroko found him, he was murdered by a Mercurius that he himself summoned. It is later revealed that his portal opening failed due to him using an incorrect doll in the ritual.
