The Tensura web novel follows the story of Rimuru Tempest. He starts as a normal salaryman in Japan but is reincarnated in a fantasy world as a slime. Rimuru then begins to build his own nation and gathers various powerful and unique beings around him. He also gets involved in many power struggles and battles against other strong entities in this new world.
Personally, I think both have their own merits. The Tensura manga is great for those who are new to the series or just want a more straightforward visual experience. The panels are well - drawn and can easily show the progression of the story. On the other hand, the light novel is a treat for those who love to get lost in detailed worlds and complex character development. It allows you to use your imagination more as you read the detailed descriptions. So, it's really a matter of whether you value the visual aspect more or the detailed written content more when deciding which one is better.
Some local libraries might also have the Tensura novel in their collection. You can check their catalogue and borrow it if available. Additionally, there could be some fan - made translation websites, but make sure they are legal and reliable sources.
In the Tensura web novel, Rimuru Tempest is the central figure. He is a slime with unique abilities. Shuna is another important character. She is often involved in the management of Rimuru's nation. Diablo, a powerful demon, is also a main character. He serves Rimuru and is extremely powerful in combat. These characters, along with many others, contribute to the development of the story, with their different personalities, abilities, and goals.
One popular tensura fanfic might be those that explore different character relationships. For example, stories that focus on Rimuru's interactions with his newly formed kingdom's citizens in more in - depth ways. It could show how his leadership impacts individual lives.
