The theme of being 'betrayed' isn't overly utilized in isekai, but nearly all series with this theme are highly captivating.
1. Her Majesty's Swarm
Unlike other works, Her Majesty's Swarm takes a completely different direction, even when compared to other isekai with the theme of the main character being betrayed. The story follows an eighteen-year-old college student who, in a strategy game she's playing, chooses to play as a demon faction named Arachnea. Suddenly, for some reason, her body shrinks, reverting to her teenage years, and she becomes the ruler of the Arachnea army.
Quickly adapting, she builds and develops her Swarm army and establishes an alliance with the forest-dwelling race of elves nearby. However, a group of slave hunters arrives in the forest and kills one of her Swarm creatures. Things take a turn for the worse when a group of knights from a nearby kingdom arrives to burn down the elf village and massacre all its inhabitants. This truly enrages her, leading her to plan revenge against the entire world.
2. Tsukimichi: Moonlit Fantasy
Tsukimichi: Moonlit Fantasy, also known as Moonlit Fantasy, tells the story of Makoto Misumi, just an ordinary high school student leading an ordinary life. One day, he's suddenly summoned to another world to become a 'hero'. However, the world's goddess scorns him for his differences, stripping away his 'hero' title before casting him into the wilderness on the world's fringe.
While wandering in the wilderness, Makoto encounters dragons, spiders, orcs, dwarves, and various non-human tribes. Coming from another world grants Makoto the ability to unleash magical prowess and combat skills beyond imagination. But how will he handle encountering various species and surviving in a new environment? In this scenario, Makoto strives to turn the other world into a better place despite humans and deities turning their backs on him.
