Kyuutei wo Kubi ni Natta Shokubutsu Madoushi wa Slow Life wo Ouka suru: Nonbiri Sekaiju wo Sodatetara, Saikyou Ryouchi ga Dekimashita

In Leet's previous life, he died of exhaustion after a life as a corporate slave. After his reincarnation, he is revered as a hero for using his rare "plant magic" skill to end the war, but he is framed by his colleagues and expelled from the court. "I can finally make my ideal village!" Leet, who originally wanted to live a slow life, obtains a run-down plot of land, and freely manipulates plants to enjoy his slow life as he pleases. The village becomes more and more prosperous due to Leet's unintentional cheats, and Leet is visited by a flower girl, a cat girl, and even an imperial princess...? (Source: Akita Shoten, translated)
