転生したらスライムだった件 異聞 ~魔国暮らしのトリニティ~

In That Time I Got Reincarnated as a Slime: Trinity in the Demon Country (2019–present, Kōdansha), this spinoff manga shifts focus from the main series' nation-building to the daily lives of three original characters—a demon, a dwarf, and a lizardman—who become citizens of the monster nation Tempest. Written and illustrated by Tae Tona, the series expands the world of Rimuru Tempest through lighthearted slice-of-life adventures, offering a warm, character-driven counterpoint to the epic fantasy of the original story. With 13 issues and counting, it’s a charming companion piece that deepens the setting’s sense of community.
