Shin Megami Tensei V: Vengeance Low-Level Challenge - Part 16 [Check Description]

Peak gaming time!
The rules:
Fresh NG file, Canon of Vengeance.
Hard playthrough.
Only ONE demon per species (another one can be contracted, but then the first one gets kicked out) [Will be canned if no progress is feasible.]
Only mandatory battles.
No powerups (Gospels/Balms/Incenses/Sutras/Haunts).
No Omagatoki: Luck.
No DLC.
Miracles, Grimoires, Items and Fusion Accidents are fair game.
