Möbius Brides

Dungeon and Bride is a strategy/tactical hybrid RPG with heavy visual novel elements and dungeon crawling mechanics.
You play as a Theo, a rookie adventurer who is looking to became a respected demon hunter like his late father and hopefully also find a beautiful bride in the process.

At just 20 years old, your life is about to change forever. After the tragic loss of your parents, a mysterious benefactor has provided you with a luxurious home and a chance at a bright future. But there's a catch: his will stipulates that you must marry one of his three enchanting daughters within days to secure your inheritance. With the benefactor's wife and daughters now living with you, your life becomes a whirlwind of passion, desire, and complex relationships. As you navigate this new reality, every decision you make could lead to love, passion, or even a harem full of lasciviousness.

Through the slots, you must “bring” Konoha’s body to ecstasy and complete the quota before the “death deadline.”
If you fail, the floor will collapse, and you will “fall.”
The only way to survive is to completely “develop” her with your own hands…

Having lost her grandmother, Shirafuji Sana found herself completely alone. With nowhere else to go and nothing to eat, she turned to the Imperial Army and its strange 'bride thorn' program.

Bride thorns are girls offered up as rations to the Vampdolls - blood-drinking women conscripted into the Army as its fiercest soldiers. Starved, desperate and completely unaware, Sana was made to sign an enlistment contract, only to be promptly introduced to Hanafusa Yukine, a beautiful, yet scornful Vampdoll.

At first, the two were far from an ideal match. With time, however, little by little, they began opening their hearts to one another. On their first night, they learned just how exhilarating - physically, emotionally - sucking blood can be. This came as a shock, but the two, awkwardly, trustingly, successfully made it through their first feeding.

Not long after that, they were sent out for active service and Yukine was incapacitated in the fighting...
