   Summary

   He observes Saika Takao roams inside the Metaverse, stealing treasures alongside the other Phantom Thieves.
   That girl is no Persona user, but instead, a Demon Summoner.
   No trace of rebellious will could be found in her heart; a heart of a perfect pawn.
   One day, Law and Chaos will come to clash.
   Under his guidance, Saika will have no choice but to bathe in the blood of her friends and recreate the world through the Conception.
   A world without crimes or lies, just like what he intended.

   Or,

   What if SMT demons replaced Persona shadows? What if more mythological figures participated in the 'game'? What if an OC joined the Phantom Thieves? What if there are various SMT elements and characters in P5R? Basically, a bunch of 'what if' inside a single fic.

   It could be read fandom blind (or at least, you can read it without the context of one fandom)
