True Demon EndingBroadly, this requires doing two separate but inter-connected things; defeating the ten Fiends and completing all five Kalpas in the Labyrinth of Amala. A scene will occur at the bottom of the Labyrinth of Amala, and the player will be locked into the True Demon Ending, regardless of prior alignment.
Note that the True Demon Ending adds an additional final boss that is significantly more difficult than the normal final boss and requires very specific preparation.

Matador – Story boss
First Kalpa unlocked
2. Daisoujou – East section of the area outside of the entrance to the Mantra HQ
3.
Hell Biker – Walk south on the highway near the (previously blocked) exit from Mantra HQ
Second Kalpa unlocked
4. White Rider – Finds YOU after you witness a scene at the entrance of the Third Kalpa (may require going to the Terminal in Asakusa)
5.
Red Rider – Outside Terminal in Great Underpass of Ginza
6.
Black Rider – Room 204B in Shinjuku Medical Center, after completing the Obelisk
Third Kalpa unlocked
7.
Dante – Third Kalpa. I am not sure if he influences the appearance of any of the others, but it is probably best to defeat him as soon as possible
8.
Pale Rider – Asakusa, will be encountered during the story if other Fiends have been defeated, before going to Yushima Station
9.
Mother Harlot – After completing Yoyogi Park, at the West Park Entrance
10.
Trumpeter – Yarakucho Station, will be encountered during the story if other Fiends have been defeated
Fourth Kalpa unlocked
The Fifth Kalpa is unlocked by defeating Beelzebub in the Fourth Kalpa and then:
"Returning to the Second Kalpa and talking to the Efreet at the end of the Cursed Corridor, talking to Loki in Nyx's Lounge in Ginza, and finally receiving the Star Key from the Collector Manikin in Asakusa. The key must be used to open the locked door in the Third Kalpa and using the alternate Warp Zone to activate the switch in the Fourth Kalpa. The Candelabrum required to open the Fifth Kalpa is none other than the one given directly to the Demi-Fiend by the Lady In Black."
