I'm not entirely sure as I haven't read it in full. But generally, it might be about the adventures of a slime in a reincarnation - like story. It could involve the slime evolving, making friends or foes, and exploring a new world.
Well, the title 'tensei ni hakobijin no isekai kouryakuhou novel' gives some clues about the novel. 'Tensei' usually refers to reincarnation, which is a common trope in isekai stories. 'Hakobijin' could be some sort of important figure in the story. The 'isekai kouryakuhou' might suggest a strategic or planned adventure in the other world. Without reading it, we can only guess that it may have a story full of fantasy elements, with the protagonist using their new - found identity or abilities in the isekai world to face various challenges and grow.
I'm not entirely sure specifically as there could be many different stories within this genre. Generally, 'isekai' often involves being transported to another world, 'onsen' is a hot spring, and 'tensei' might refer to reincarnation in a novel context. So it could be about a character being reincarnated in a world with hot springs.
A 'succubus ni tensei light novel' might tell a story full of fantasy and adventure. The succubus could be the main character who is on a quest. Since it's a light novel, it might have a mix of action, some comical moments, and a bit of romance. For example, she could be in a world where she has to fight against other supernatural beings while also trying to understand her new succubus identity. And perhaps she meets a group of allies or a special someone during her journey.
One unique feature is the slime as the main character. It's not a common choice for a protagonist, which makes the story stand out. Slimes are usually considered weak or minor creatures in most fantasy settings, but here it becomes the center of an interesting adventure.
