Premise

Takeru is frustrated with his hectic life, wishing for a change. While watching TV after work, he suddenly wakes up in the domain of the overseer of the universe, or "god". Informed that he died, Takeru accepts being reborn on a magical planet called Madeus. It turns out that Madeus' civilizations keep collapsing due to the failures of the inhabitants, so God wishes to cause a ripple effect to stop this cycle; by introducing an outsider with new ideas and perspectives to the world.

Characters

A Japanese salaryman who gets sent by a mysterious god to the world of Madeus so he can help its civilizations avoid collapse. To facilitate his tasks, he is resurrected as a gatherer of resources and blessed with magic.

A child of Voldius, the ancient dragon living beneath a mountain. It had trouble hatching because its egg had been tainted by impurities in Voldius' lake, but Takeru infused it with his own magic and helped it hatch. Upon its birth, Takeru gives it the nickname "Bee" and Voldius entrusts it under Takeru's care.

A high-elf that had embarked on a journey to find a mysterious white horse that their sister was searching for. They are left starving and unclean while traveling across the woods but Takeru helps them. They become friends and Takeru hires them as a bodyguard during his journey to the dwarf kingdom Voszraol. They are a fighter who has mastered the use of dual knives. Although initially referred to as female, it is later revealed that they are intersex and accept both "him" and "her" pronouns.

A Lizardman and a veteran from the adventurers' guild at Belkaim City. He befriends Takeru and is one of the very few people that know that Takeru is not native of Madeus. Long ago, he inadvertently liberated Voszraol from a demon king, a deed that Clayston is embarrassed about because he feels that he did nothing of importance. He suffered injuries that affected his ability to fight until Takeru healed him with water from Volidus' lake, which also had the side effect of turning him into a Dragonewt.

A Pegasus that protected the village of Ashleth by constantly absorbing the toxins in its lake and a rare flower to blossom nearby. Unfortunately, such an effort caused her to exhaust all her power and turn into stone. She was only awakened when Takeru purifies the lake and, as a result, she saves his life and decides to accompany him in his travels by taking a human form.
