Utsu Tenkai Daisuki Shujinkou VS Yasashii Sekai: Tenseisaki ga Heiwa Sugiru node, Shikou no Zetsubou wo Motomete Tabi ni Demasu

A man who loves the "depressed development" where the protagonist's body and mind are beaten to their limits, only to rise from despair towards a happy ending, has died because of a Goddess's gaffe. As recompense, the Goddess offers to reincarnate him, so he wishes for a "world where he can watch depressing plot twists firsthand." However, due to a misunderstanding, he is reborn as Lyra, the prince of a super peaceful country with no war and no bad government! Reaching his limit in a life lacking dramatic misery, Lyra sets out in search of the depressing developments he has yet to see...!
