日本のメディア: Overlord by Kugane Maruyama

I recently finished season 4 of Overlord, based on the light novels by Kugane Maruyama. I currently own all fourteen volumes of the light novel that are translated to English. This fourth season has been among my favorites yet, and incorporates content from volumes 10, 11, and 14.

Cover of volume 12

The series follows main character Ainz Ooal Gown, an undead magic user who reigns over the fortified dungeon of Nazarick. The main character was formerly known as Suzuki Satoru, an average salaryman of Japan before being transported to a world resembling one of a videogame he used to play where he now is trapped. The show is considerably dark in themes and subject material, and follows the main character as he leads his newly formed nation in the search of comrades that are now gone.

SPOILERS: By the fourth season, Ainz has lost most of the humanity he once had and is convinced by his subordinates to follow a plan of rapid conquest of the surrounding nations. The culmination of this appears in the final third of the season (covering volume 14) where Ainz makes an official change in foreign policy. It is here that he decides to fully embrace the archetype of being a ruthless villain and vows to obliterate its neighboring country after political schemes bring the two nations to war. The end of the season shows the complete and intentional destruction of the entire country, with even the capital city being reduced to rubble, and signaling a major twist as the audience is suddenly introduced to previously only hinted-at characters who present a complete upheaval in the current understanding of how the world works. 

The content of the latest books and the latest season cements this anime/book series as my favorite fiction content.
