Demon Slayer released the movie Mugen Train in 2020 and became the biggest box office hit at the time. Likewise, Jujutsu Kaisen also released the movie Jujutsu Kaisen 0 in 2021, and it too became the highest grossing movie of the year. Both of those movies took turns in smashing all kinds of box office records. And now, That Time I Got Reincarnated as a Slime is also planning to join that bandwagon.
