異世界転生騒動記 [Isekai Tensei Soudouki]

In this isekai comedy from AlphaPolis, a modern Japanese salaryman is reborn as the son of a noble family in a fantasy world—only to find his mind now hosts the consciousness of a scheming, centuries-old warlord. The series follows the boy as he navigates political intrigue, magical warfare, and the chaotic advice of his inner strategist, blending slapstick humor with kingdom-building drama. Running since 2016, the comic has been a steady presence in AlphaPolis's lineup, known for its lighthearted take on the reincarnation genre and its focus on the friction between a peaceful modern soul and a battle-hardened ghost.
