Frequently Asked Questions — That Time I Got Reincarnated as a Slime
How many filler episodes does That Time I Got Reincarnated as a Slime have?
The Slime Isekai anime has approximately 3 filler episodes across its run. The series (also called TenSura) is adapted closely from the light novel and manga by Fuse.
Is there a Slime Isekai Season 3?
Yes. Slime Isekai Season 3 has been confirmed and is expected to air in 2025–2026, adapting content beyond the Walpurgis arc. The manga and light novel are far ahead.
How powerful does Rimuru become?
Rimuru eventually becomes a True Demon Lord (after the Tempest arc) and later reaches God-level power in the light novel. He starts as a weak Slime but his Unique Skill "Predator" allows him to absorb and replicate the abilities of anything he devours.
Is Rimuru male or female?
Rimuru is technically genderless — as a Slime, he has no physical sex. He was formerly a middle-aged Japanese male named Satoru Mikami. He uses male pronouns (he/him) and eventually manifests a feminine appearance as a child-like humanoid.
What is Unique Skill Predator in Slime Isekai?
Predator is Rimuru's starting unique skill that allows him to absorb and devour any substance, including living beings. He can analyze and replicate their abilities, appearance, and properties. It is the source of most of his acquired skills.
Does Shizu ever recover?
No. Shizue Izawa (Shizu-san) is already terminally ill when Rimuru meets her and dies at the end of their encounter. Rimuru absorbs her soul and inherits her mission to protect the hero children she taught.
What is Tensura chronological order?
Watch order: Slime Isekai Season 1 → Tensura Nikki (slice-of-life side story, optional) → Season 2 Part 1 → Season 2 Part 2 → Season 3 (upcoming). The original Season 1 OVAs are side stories best enjoyed after Season 1.
