A young tensura fan who had just reached adulthood immediately finds the current stage in his life to be overwhelming. With so many things to keep track of, he holds doubt that he has a place in this world. "I don't think I could survive in this world," a thought that consistently flows through his head, and as if fate decided to be cruel, he met an early end. He despaired at the thought of the rest of his existence forever residing in an unknown Void, but as he was about to force himself to accept his eternal fate, he regained his sense of touch. It felt unfamiliar, but yet he knew he touched something. He lived once more but no longer as a child of Man, but now as a monster, specifically the weakest race, a slime. he came to realize that he reincarnated in his favorite isekai, "Tensura," and not someone set to be a background NPC character but as the third Tempest sibling alongside side Rimuru and Veldora. For any reincarnated person, such an opportunity would be a dream come true, and it was for our protagonist, but this gift came with a few strings attached. he will also come to realize that living in a fantasy world that holds lots of monsters, demons, and gods that want to kill you isn't actually that fun to be in especially for someone who has a mind of an anxious oddball
This is a tensura fan-made project that has no association with the "thattimeigotreincarnatedasaslime" franchise which is officially made and owned by Fuse, please support the official realizes.
