The idea to fight for survival and along side a partner is a theme in both series. FSN and Devil Survior 2 The Animation brings together a master and a servant/partner where they struggle for survival. Thus, there's also drama and action present from both series.
This all starts on a faithful day that would change the main male protagonist's life as they knew once before forever.
At the same time, the MC tries to fight for what they believe in along with his friend and partner/servant.
