About Tensura names

Tensura is the fan shorthand for That Time I Got Reincarnated as a Slime, and naming is at the heart of the series: Rimuru hands out names to the monsters who join him, and each group gets its own pattern. The ogres who become kijin receive Japanese names built on color words (Benimaru, Shuna, Souei, Hakurou). Goblins get quick Gob- and Rig- names such as Gobta and Rigurd, lizardmen and wolves short names like Gabiru and Ranga, and orcs a blunt single syllable in the manner of Geld.

Other families work differently. The true dragons all begin with Vel-. Demon lords carry Western names, often a full one: Milim Nava, Leon Cromwell, Luminous Valentine. The primordial demons are known first by a color in French (Noir, Blanc, Rouge) and later take names shared with sports cars, such as Testarossa and Carrera. Otherworlders summoned from Japan keep ordinary Japanese names like Shizue Izawa and Hinata Sakaguchi.

This list spreads its names across those families, mixing well-known characters with originals for OCs and fan fiction: Ginmaru and Kurenai for kijin, Gobru and Rigord for hobgoblins, Velmyra for a dragon, Seraphine Nocturne for a demon lord, Vermeil for a primordial. Romanized spellings vary between releases (Souei or Soei, Hakurou or Hakuro), so each canon name appears once in a common spelling.

How to choose Tensura names

  • Choose the family first. A monster named by Rimuru, a demon lord and a summoned Japanese student follow three different naming systems, and the name tells readers which one your character belongs to.
  • For a kijin, build on a color or metal and add a traditional ending: Aomaru, Shirogane, Kokuei and Beniha sit naturally beside Benimaru and Souei.
  • Goblin names are meant to be quick and a little silly. Run a set of siblings down the vowels (Gobra, Gobri, Gobru) the way a tired namer would.
  • Give a primordial demon two names: a French color for its ancient title and an elegant single name for the one it receives later, such as Carmin and Tempesta.
  • Spell canon names the way your source does. Romanizations differ between the novels, manga and anime subtitles, so pick one and keep it consistent.

Frequently asked questions

What does Tensura mean?

It is the common short form of the Japanese title Tensei Shitara Slime Datta Ken, known in English as That Time I Got Reincarnated as a Slime. Fans use Tensura, TenSura or simply Slime for the novels, manga and anime.

Are all of these names from the series?

No. Familiar characters such as Benimaru, Gobta, Veldora Tempest, Milim Nava and Testarossa are included, but most entries are original names written in the same patterns, like Tetsumaru, Zabiru or Lucian Ashcroft. The originals are not canon, and the list makes no attempt to cover every character.

How do I name a Tensura OC monster?

Decide who named the character and follow that habit. One of Rimuru's ogres would get a Japanese color name such as Kinrou or Rurika, a direwolf a short name ending in -ga like Raiga, and a lizardman something close to Gabiru, such as Kabiru.

Why are some demons named after colors and cars?

In the series the oldest demons are first referred to by a color, given in French, and several later receive names shared with sports cars. This list follows the color habit with words like Azur and Grenat and keeps car words to a handful.
