People picking up a physical copy of Gal Gun 2 will find a surprise inside. It turns out PQube will be localizing Punch Line, the 5pb visual novel based on the anime series of the same name. It will be released in Summer 2018. (Thanks, Oldmario on Resetera!)
The Punch Line ad in copies of Gal Gun 2 does not state a platform for the game. However, it originally released on the PlayStation 4 and PlayStation Vita in Japan in 2016. It follows Yuta Iridatsu, whose soul and body were separated. He has a unique ability where seeing girls’ underwear once will give him brief super strength, but seeing them twice will cause a meteor to destroy Earth. (However, if the meteor does fall, Yuta will go back in time and have a chance to keep this from happening.) Players help him try to return to his body while also protecting the young women who live in the Korai House apartments with him. Kotaro Uchikoshi, known for the Infinity and Zero Escape series, wrote the Punch Line anime, manga and game scenario.
Punch Line is immediately available on the PlayStation 4 and PlayStation Vita in Japan.
