"By the Grace of the Gods" is a fantasy isekai anime series that centers on Ryoma Takebayashi, a reclusive man who dies in his sleep and is reincarnated into a magical world by three gods. The gods grant him divine blessings, including enhanced physical abilities and an affinity for magic, as a reward for his virtuous life. Ryoma is reborn as a young boy and begins his new life in a forest, where he befriends slimes, low-level creatures often dismissed as weak. Through experimentation and his unique connection to the slimes, Ryoma discovers their untapped potential, training them to perform tasks like cleaning, cooking, and even combat.

After spending years in solitude, Ryoma encounters a group of adventurers who introduce him to human society. He moves to a nearby town, where he begins to integrate into the community, taking on odd jobs and forming relationships with locals. His expertise with slimes earns him recognition, and he establishes a laundry service using his trained slimes, which becomes a popular business. Ryoma’s kind and humble nature endears him to many, including the noble family of the town, who take an interest in his abilities and offer him support.

As Ryoma navigates his new life, he encounters various challenges, including bandit attacks and magical beasts, which he handles with ingenuity and the help of his slimes. His journey also involves learning about the world’s magic system, forging bonds with adventurers, and uncovering the mysteries of the gods who reincarnated him. The series balances slice-of-life elements with light fantasy action, focusing on Ryoma’s growth as he adapts to his new environment and uses his unique skills to help others. The narrative emphasizes themes of kindness, perseverance, and the value of overlooked creatures like slimes, all while maintaining a gentle, episodic pace.
