"The 4th avatar of Vishnu. He took his form to defeat Hiranyakashipu, who can't be killed by human, animal or deva, and killed his foe at dusk, since he couldn't die at other times."
Narasimha is the avatar of Vishnu, a deity in Hinduism. The story goes that Vishnu had killed the Asura Hiranyaksha. Hiranyaksha's brother Hiranyakashipu was angered by this, and vowed to kill Vishnu. To do so he must gain immense mystical powers, which he believed will be given by Brahma if he underwent many years of penance. Brahma was pleased with Hiranyakashipu's efforts and granted him a boon, in which he asked for protection from death by human, deity or animal in any space by any weapon in any time. With the boon he attempted to kill Vishnu, but Vishnu took upon the avatar of Narasimha - part deity, part animal - and managed to slay Hiranyakashipu.
"Origin: India. One of Vishnu's ten avatars. He is a human with a lion's head. Hiranyakashipu, the immortal king of the Rakshasas, tried to kill his son. Narasimha defeated Hiranyakashipu in retaliation."
Narasimha can only be acquired through fusion. He is particularly notable for being one of the few demons that gain a powerful suicide affinity attack boosting feature after Mitama fusion. He appears with Vishnu when he acts as a boss.
An Angel of Muspellheim, he is faced as a boss in Ice Book. Narasimha is the angel who disguised himself as Berith earlier in the story. Along with his disguised comrade Ictinike, they would seal away Zebul as a statue in Muspellheim. He will later be fought in his true form in the destroyed Future Harajuku, where he stands guard of the Gate and shows Akira the world sacrificed for the sake of the eternal battle. Upon his revival after beating the story, Narasimha will stay in the entrance to the Deep Hole.
