In Digital Devil Story: Megami Tensei
Loki serves as the major antagonist of Digital Devil Story: Megami Tensei. Nakajima Akemi summons Loki and has him get revenge on several students at Jusho High School. Loki seizes control of several students bodies and murders the students that Nakajima wanted revenge on. Loki then demanded women be sacrificed to him, eventually allowing him to impregnate Ohara, one of Nakajima's teachers. While Nakajima was no longer watching, Loki practiced at teleporting through computer screens and taking physical form, which he eventually uses to rape and kill Yumiko Shirasagi, one of Nakajima's fellow students who happens to also be the reincarnation of Izanami. Nakajima attacks Loki with Cerberus and then escapes to Asuka, where he plans to resurrect Yumiko. Loki, angry at being injured and fearful of Nakajima summoning other demon lords that could compete with him, follows Nakajima to the tomb with the hopes of killing him. Loki kills Yomotsu-Shikome and he causes Yumiko's body to rot and attack Nakajima in an attempt to break his spirit. Izanami appears to fight Loki, but Loki captures her and prepares to rape her. Nakajima manages to summon Hi-no-Kagutsuchi as a sword and uses it to kill Loki.
