Ren AI Flag ~AI ga Risou no Koibito o Erande Kureru Matching App o Tsukattara Isekai no Yuusha to Matching Shita~

Ryouta Midou finally achieved the vibrant university life he had always dreamed of, yet one persistent problem continues to plague him: despite his best efforts, he remains completely unsuccessful in finding a girlfriend. Desperate for a change in fortune, he clings to a last shred of hope by downloading "Ren AI Flag," a matchmaking application recommended by a friend that uses artificial intelligence to pair users with their ideal partners. To his absolute astonishment, the app delivers a seemingly perfect match—a breathtaking blonde beauty named Lilia. However, Ryouta's excitement quickly turns to bewilderment when he discovers that Lilia is no ordinary girl; she is actually a hero who has crossed over from another world entirely. What was supposed to be a simple attempt at romance spirals wildly out of his control as Lilia immediately pressures him into a serious relationship with marriage firmly in mind. Before he can even process the situation, the two unexpectedly end up living together under the same roof. Thus begins a delightfully unconventional romantic comedy following a male university student who simply wanted an ordinary love life, only to find himself entangled with a heroine from beyond his world.
