when rimuru is signing his paperworks for 500 years of torture, he suddenly got an idea of how to cure his boredom. to travel to another world! but after many years of travel between different worlds, his next travel will be his exact same old world where he lived as a human. he then decided to get reborn here and start a normal life. and after he turned 12 years old, he started his High school life. but one of his classmate is strangely different, he's not from the Cardinal world or a human or even the one he encountered through different worlds but... a completely Unknown being. I do not own Ttigraas, if you see any wrong sentences or grammar please forgive me cuz I'm not good at english, all the photos I'll be using is not mine and belongs to their respective owner. But some of it are my own drawings. There will be some memes along the story, It will be at least 1500 - 2000+ words each chapter. And this is my first story so please enjoy :).
