Red Rider can be fused by any combination of demons resulting in a Fairy.
Shin Megami Tensei IV
Red Rider is one of seven fiends available to fight as an optional battle. He is found in Kasumigaseki, in the underground area that requires ID Card Lv3 to access; for this reason, he can only be fought on the Neutral route. He has a 1/256 chance of spawning behind the door that requires 100 Luck to open; if he doesn't show up, a message displays pops up saying that nobody is present. His Almighty-spam mode is set by Fire resistance. Defeating him awards you with a Soma, 10 of each incense, and the ability to obtain him through special fusion.
Red Rider is fought alongside the other three in the Challenge Quest, Errand for the Apocalypse. Belial has sealed the four in a Domain found in Infernal Tokyo's Ikebukuro. They are far weaker than they are when encountered normally, that does not make them any less threatening. If Flynn makes any attempt to challenge them before accepting the quest, the Fiends will eject him from the domain. Completing the quest grants Flynn the Peacemaker, which is only surpassed by the plasma gun in terms of raw power.
