The 'Tensei Shittara Slime Datta Ken Light Novel' has influenced the isekai genre in multiple ways. For one, it popularized the concept of a non - human lead in a reincarnation story. It also showed that an isekai story can have a more light - hearted and comical tone while still having an engaging plot with elements of adventure, politics, and character growth. This has led to other isekai works exploring different tones and moods.
This light novel has had a significant impact on the isekai genre. It introduced a unique power - up system that has been emulated in other works. The way it developed the world around the protagonist, with different species and cultures, set a standard for world - building in isekai. Moreover, its success has encouraged more works to explore the idea of a character starting from a weak and unassuming form (like a slime) and gradually growing into a powerful entity. This has broadened the scope of character development in the isekai genre.
