You might be able to find it in some specialized bookstores that carry a wide range of light novels. Also, online platforms like Amazon or Barnes & Noble could have it available for purchase, either in physical or digital form.
Well, I'm not that familiar with 'slime saint light novel' specifically. But generally, light novels often have unique settings and characters. You could try looking for it on some light novel platforms or forums to find out more details like its plot, main characters, and the overall theme.
Well, one obvious difference is the medium. Manga is visual, so you can directly see the slime's appearance, the expressions of characters, and the action scenes. For example, in a slime battle scene, the manga can show the slime's movements vividly. However, a light novel uses words to describe all these. It might describe the slime as a gooey, translucent blob that pulsates with a strange energy.
Well, without more context, it's difficult to say exactly. 'Slime' in light novels often refers to a type of creature, which can have various forms and abilities. The '300' might be a volume number, a chapter number, or something else entirely. It could be a story where the slime is the protagonist and there are 300 important elements in the plot, like 300 quests it has to complete or 300 different types of magic it encounters.
