■ Prologue

At Anberyl Girls Academy, there is legend of a mysterious Holy Grail that can grant any wish. The holy grail is hidden deep inside an ancient cave at the academy. The cave, which is usually off limits, is opened only on the anniversary of the academy’s founding. However, while the Holy Grail was found by some students, it was for some reason destroyed, and that became the true legend… or that’s what was expected… The girls’ adventure surrounding the Holy Girl will begin once again…

■ An Orthodox Roguelike RPG

Like the previous game, Omega Labyrinth Z is an orthodox roguelike RPG featuring “automatic dungeon creation,” “a reset to level 1 each time you enter the dungeon,” “losing all your items when you die,” and a “hunger level.” Each time Aina and company enter and challenge the dungeon, the map, monsters, and items will change. In the dungeon, the player and monsters move in a turn-based system. Defeat monsters, accumulate experience points, and level up to strengthen your character.

When you exit the dungeon, you’ll return to level 1, and when your HP is reduced to zero, you’ll lose all of the items you’re holding. Also, you can take along one partner character in the dungeon that will follow you. Of course, your partner can also be equipped with weapons and armor, and given instruction based on the battle situation. Together with your partner, aim to clear the dungeon while using the weapons, armor, and items you obtain in the dungeon, and while overcoming the monsters and traps within.

■ Don’t Just Level Up! Chest Up!

By defeating the monsters lurking within the dungeons, you’ll accumulate “Omega Power,” which is a power that embodies the girls’ strength and is different from experience points. Omega Power gathers in the chest, and the more you collect, the bigger the girls’ chests gradually become.

However, not only do the girls’ chests get bigger,their stats will also increase in a different way from leveling up the higher their breast cup size increases. Additionally, for each increase in chest size, an “Exploding Breasts Mode” where your stats are doubled can be used. In Omega Labyrinth Z, the number of times this mode can be used increases by one for each bust size increase, and can be activated at your preferred timing.

Unfortunately, exiting the dungeon will return the girls’ chest sizes to normal, but you can use the Omega Power you gathered in the dungeon to purchase and appraise items. Increase your chest size, enhance your stats, and buy and appraise items—this is the power of dreams, this is Omega Power.

■ Z Chest Mode

The biggest bust size in the previous game was K-cup, but in Omega Labyrinth Z, if you continue to build up Omega Power when you’re at K-cup, you can activate “Z Chest Mode,” in which your bust size immediately becomes Z-cup and your stats are significantly enhanced.

Furthermore, you can use the ultimate special move “Hyper Omega Slash” just once, which deals a great amount of damage to monsters in the 3×10 square ahead of you, as well as destroys the dangerous traps set in the dungeon. Hyper Omega Slash is super powerful, but the character’s bust size will return to its default after it’s triggered and items within the attack range will be destroyed. Know when to use it!

■ Appraise Unknown Items

In the dungeon, you may obtain items that are unidentified crystals, whose item name and effect you won’t know. Items with unknown effects can be appraised by directly pouring the Omega Power you’ve gathered into the item.

It’s extremely easy to do. Just prop the unidentified crystal in between the chest, then fondle the breasts. The more stimulated the crystal, the more Omega Power is poured into the item, gradually expanding the item. An item that has reached its limit will no longer be able to contain its unidentified form and the source material will spurt out, revealing its true nature.

The character used for item appraisal can be chosen from among your party. Appraisals after escaping a dungeon are unfortunately appraisals with default size chests, but you can appraise items with big chests while exploring the dungeon. The results of an appraisal don’t change based on character and bust size, so you can appraise items with your favorite girl. If you don’t want to go about the appraisal scene, it’s also possible to skip it. Find unidentified crystals, prop them between the girls’ chests, and fondle away until the source material is revealed.

■ Faint in Agony Awakenings

“Faint in Agony Awakenings,” in which you increase your initial stats and acquire new skills, and are indispensable for strengthening characters, will of course appear in Omega Labyrinth Z. By bringing back and using “Faint in Agony Aroma” (Omega Power solidified into an aroma), the girl will become excited and have a variety of delusions.

Omega Labyrinth Z has new situations where you can see unexpected and new sides to the girls. By touching the heart marks that emerge on the girl’s body during this delusion, the Omega Power will pour in and the mood will escalate. As the level of excitement rises, your stats and skill acquisition experience points will increase. When the level of excitement reaches a certain point, a “Sen-sitive Spot” will appear.

The girl’s level of excitement will increase the more you touch spots that aren’t the Sen-sitive Spot. However, if you tease her too much, she’ll cool down, so be careful not to do that. If you further increase her level of excitement, she’ll enter a “Shyness Break” where her whole body becomes sensitive. By continuing to touch the same spot during a a “Shyness Break,” the girl’s climax zone, the “E-Spot,” which goes beyond the Sen-sitive Spot, will appear. Touching the E-Spot will significantly increase her level of excitement.

Faint in Agony Aroma

You can use multiple Faint in Agony Aromas at a time. If you use 10 of them, you can have 10 times the awakening. Also, there is only one type of Faint in Agony Aroma, you can buy your favorite delusional situations from the in-game shop, and you can choose your favorite to use when the time comes.
