I Became a Sengoku Lord! (戦国王になった！)

Hello. I am Iwasawa Hiroshi, a normal 16-year old teenager who suddenly woke up in this weird world that looks like feudal japan. With no memories save for some things that I feel strangely knowledgable about, I just wanted to live a normal and quiet country-side life as a doctor. Or atleast that was the plan... "Huh?" "All Hail our new Daimyo! Lord Iwasawa Hiroshi!" "Banzai!!!" And so, it has started... I Became a Sengoku Lord!
