Maou 2099

Maou 2099 is a modern, darker, and more serious version of Hataraku Maou-sama! Both stories start with a powerful Demon Lord losing a crucial battle and finding himself transported into an entirely unfamiliar world where his once-feared powers are suddenly useless. They struggle to live in this new world, facing difficulties with their jobs. 

Despite being different goal and background, surprisingly these two animes have more similarities. It's frightening how their concept is very much alike- • MC goes into hibernation, both animes occur in their own same universe but in future timeline - which gives them isekai vibe. • The superpower characters depend on human emotions towards them; in Maou 2099 MC's power come from positive and negative human thoughts about him . Similarly in Kaminaki sekai no Kamisama Katsudou Goddess's power comes from the more follower she has. • Most importantly, both Demon lord and goddess in these two animes have to start their journey from the beginning and challenge more powerful forces than them in their current era.  read more
