It's a non-eroge, moe ADV, so expect it to be cute rather than trangressive
"My Girlfriend is an Alpaca," officially named PacaPlus, follows the "unforgettable summer" of Saeki Kazuma, who visits Alpaca Kingdom with his friends, only to return home on the bus, look over and discover that his girlfriend, Izumi Yukari, has been replaced by a fluffy white animal. The visual novel from PacoProject is now being offered with the doujin circle's English translation.
