Generic Isekai Jumpchain (2017)

From the introduction: Literally, the word ‘isekai’ simply means ‘another world.’ But the term has come to define a genre of stories, each about an ordinary protagonist from an ordinary world, transported to a world of fantasy. Swords, spells, dungeons and dragons; orcs and slimes and elves. All those fantasy tropes and more, along with powerful abilities granted to the protagonist, to ensure that he always comes out ahead.
