Isekai Ojisan  

Uncle from Another World, 異世界おじさん

Three decades have passed since Takafumi's uncle fell into a coma. Now he has awakened as if he had risen from the dead. Soon after, Takafumi discovers that his uncle is obsessed with video games and that while in a coma, he was transported to another world as a heroic guardian. As a result, Takafumi must now live with an uncle who possesses magical abilities and needs to be brought up-to-date on two decades of technological advancements, including smartphones, high-speed internet, modern anime tropes, and the aftermath of the '90s console war.

Isekai Ojisan has been published in English as Uncle from Another World by Yen Press since June 8, 2021.
