Isma Feed (イスマ, Isuma)? is one of the antagonists of Digital Devil Story 2. A sorcerer from Salem and brother to MIT professor Charles Feed, he wishes to summon the demon Seth into the world and make a pact with him.
Shortly after Akemi Nakajima's defeat of Loki, Isma learned of his Demon Summoning Program and left for Japan. There, he found Ohara, who had used the program to summon Seth. Relocating to an abandoned hut in the Soga Forest, Isma used the Demon Summoning Program to summon Seth and makes a pact with him, promising to summon him into the world and aid him in conquering it. In time, Isma succeeded in summoning Seth into the Assiya world, though this is in part due to Seth being summoned in the body of Ohara and Loki's child and due to the high amounts of Magnetite inside Yumiko Shirasagi, who Seth uses as the "heart" of his current form. Isma and Seth then begin to hypnotize the people of the nearby cities into being mass sacrificed to build Seth's true body and merge the Assiah and Atziluth worlds, and Isma summons Typhon to guard over the ritual.
When Nakajima, Charles, Narukawa, and Cerberus make their way towards Seth, Isma merges with Typhon and engages Nakajima and Cerberus in battle. After Nakajima is knocked back by Isma/Typhon, Isma taunts him about how Yumiko is Seth's prisoner and how even if they need her, the two will torture her to make Nakajima suffer. At seeing Nakajima's suffering, Narukawa awakens to his power as the reincarnation of Tsukuyomi and quickly kills both Typhon and Isma.
