From "That Time I Got Reincarnated as a Slime" Season 4, which begins broadcasting on April 3, the synopsis and preview stills for Episode 73, "New Days," have been released.
Following the Founder's Festival, Tempest takes its first steps toward the "Human-Monster Prosperity Zone." However, behind the scenes, the former Hero Granbell (CV: Daisuke Ono) and his granddaughter Mariabell (CV: Inori Minase), who view Demon Lord Rimuru's (CV: Miho Okasaki) rise to power as a threat, are weaving a sinister plot. Furthermore, Demon Lord Leon (CV: Jun Fukuyama) begins to make his move. As a new Hero is about to awaken, the intentions of each faction intersect, marking the start of Rimuru's next battle. It has been confirmed that the fourth season of the TV anime will be broadcast in five split cours, starting with two consecutive cours this April on NTV-affiliated stations and BS11.
