My Yusha-sama!

Since ancient times the Demon Lord has kidnapped a princess to lay in wait for the Hero at Demon Lord Castle. However, records show that these princesses responded to their kidnappings in many different ways, with some falling in love with the Demon Lord as they spent time with them, some hitting it off with the Demon Lord and joining them in their quest for world conquest, and some who tried to defeat the Demon Lord before the Hero arrived. So -- what fate awaited Princess Rona when she was kidnapped by the Demon Lord after its sudden appearance? (Excerpt from "Demon Lords Love Princesses?")
