Quoted By:
Mori's relationship with her roommate is a reverse mantling. Instead of the The Hero of Kvatch becoming Sheogorath or Setsuna F. Sei becoming Gundam, It's Sheogorath becoming the Hero of Kvatch, aka "Mori Calliope of Hololive English First Generation" becoming her roommate. It is her EGO consuming the world, not the other way around. Not only she has achieved her ikigai, but she has also achieved CHIM.
