No release date was mentioned, but the game has already been translated for a while now so I expect that it'll be on Steam very soon. The game was previously released in English but was not on Steam. Limited amounts of physical copies will be at Anime Expo next month. UGH I NEED ONE.

North American visual novel distributor Sekai Project announced on Wednesday that it will release PacoProject's PacaPlus visual novel in English. The company will have a limited number of physical copies available at its booth at Anime Expo, and customers who buy a copy of the game will receive one of two different PacaPlus clear file folders. Sekai Project will also release the title digitally via Steam.
The story follows the life of a certain Kazuma Saeki who is living the life. Surrounded by friends, especially his cute girlfriend Yukari Izumi, his school days could not be any better. However, on a bus ride back from "Alpaca Kingdom" he wakes up from a nap and finds that it's not Yukari that's sitting next to him but an alpaca. An alpaca that talks exactly like Yukari in fact...
What will happen to Kazuma and his life with an alpaca? How exactly does an alpaca play the violin? What is the connection between "Alpaca Kingdom" and what happened to Yukari? Pick up the game and get to the bottom of this fluffy mystery!
