Mushoku Tensei: Isekai Ittara Honki Dasu Part 2

similarity 1. Both anime have mc that start of weak but latter become op 2. rimuru and rudeus were middle aged men and reincarnate after dying differences 1. rimuru is slime while rudeus is a human 2. slime is about building a new town while mushoku tensei is about mc overcoming is past to become a better person  

Traveling in a similar fantasy world with presence of magic and races/species like elf, dwarf, demon and dragon. Creative worldbuilding, with inspiring scenery and backstory. Both focus on drama regarding human thoughts and emotions, learning the feeling of others, and cohabiting with others, with less for battle actions. Now the most important part, both have great storytelling and well written characters, making it easy to understand the story. Sousou no Frieren fans might not end up liking Mushoku Tensei due to presence of mild ecchi, but if you liked MT then definitely try out Sousou no Frieren 

Isekai with op mc and cute waifus. Both are pretty ecchi, with multiple races like demons and that. 

This is totally mushoku tensie level of world-building, but the stakes are a bit more relaxed. a very interesting dynamic between the characters exists.ART is also on a similar level . 

Somali and forest spirit is more advanced and better written version of good part of mushoku tensei without its bad part (aka author's obsession with sex). If u are look for more unique worldbuilding and similar adventure and slice of life themes with better and more resonating character and deep real redemption themes, I suggest somali and forest spirit. If u are looking for a more self insertable version with sex addicts finding justice and a more generic/basic, but well/similarly executed worldbuilding and much higher production quality, then u conversely go with mushoku tensei 

- Main cast travels to numerous destinations and has to fight unique enemies - Vast and interesting open-world as a main theme of the show - Made by new studios with reputable staff members - Takes place in a desert environment  

At 27 years old, Arata Kaizaki is stuck in a cycle of being unable to land a job after quitting his first job after 3 months.

This soon changes after he is given the chance to relive his life as a 17 year old high schooler for one year and will be granted a job to help him return to society. Like Rudy he thinks of his age and experience in life to be something that will help him. But just like Mushoku Tensei, it does him as much harm as it does him good. Overall he is able to relive his life gaining new experiences he was unable to have before, confronting past traumas, and helping others with his life experience.  read more
