This week’s Famitsu (via Hachima) has confirmed the Japanese release for Omega Labyrinth Z.

The new PlayStation 4 and PS Vita game will launch on July 6th in Japan. The roguelike RPG brings with it new elements not seen in the original game, Omega Labyrinth, and it takes place after the events in the first game.

The biggest change in the game is naturally the maximum breast cup size being increased from K-cup to a whopping Z-cup. Development on the sequel is roughly 70% complete at the time of publication. The game also features a new protagonist, Rio Akanezaki.

Here’s the currently revealed characters:

• Aina Akemiya (voice by Haruka Yamazaki)
• Nako Mito (voice by Aya Uchida)
• Rio Akanezaki (voice by Ayaka Fukuhara)
• Saeri Soja (voice by MAO)

As the original game featured a breast-growing RPG mechanic, once you reach the new Z-cup you’ll be able to unleash the “Hyper Omega Slash” one time. Once you use this attack, your breasts will deflate and become smaller. Both the “Omega Power” and the “Agony Awakening” mechanics from the original are present.
