Your ultimate guide to the best ReZero watch order
What is ReZero about?
ReZero tarting Life in Another World began as a web novel written by Tappei Nagatsuki, first published on the user-generated fiction site Shosetsuka ni Naro in 2012. Its popularity led to an official light novel adaptation in 2014, illustrated by Shinichirou Otsuka and published under MF Bunko J.
The anime adaptation by White Fox premiered in 2016, becoming a breakout hit for its dark twist on the isekai genre and its focus on psychological struggle. ReZero later received Season 2 in 2020 (split cour in 2020–2021), plus several OVAs, expanding into a large multimedia franchise.
The ReZero narrative follows Subaru Natsuki, who is transported to a fantasy world and cursed with the ability “Return by Death”.
This forces him to relive moments of suffering until he finds a path forward. Unlike typical isekai heroes, Subaru’s growth comes not from overwhelming power but from confronting fear, trauma, and his own flaws.
With the singular goal of saving everyone, the story then unfolds across relentless timelines that challenge his sanity and the very friends he swore to protect.
