Oppai means a big chest, so chippai means a small one. Within the dungeon, there are traps called “Tsurupeta Traps.” This basically means “smooth and flat.” This trap turns your character’s breasts to A cup size between several turns. This also affects characters whose breasts are large from the get-go (like Mirei’s E cup and Hana’s F cup). These traps affect your status, and the shock of your shrinking chest means you can no longer use your skills. And since you can’t hold an item between your breasts with an A cup, that means no Oppai Appraisals, either."

So there are booby traps as well eh? Oh Japan

Speaking of which, can we call it by its actual title " *ω* Labyrinth "? Please?

" "?

That image is an attack on the senses.
