Warning: Specific Kink (Weight Gain) You challenge a mysterious tower... Testing settings and seeking feedback.
One day, you rescued a fairy. In gratitude, she guided you to a mysterious, ancient tower that no human had ever reached. What awaits you inside is... Entrance: Shrine of Choice Here you decide your class: Swordsman, Mage, or Ranger. Choosing one grants you an inventory bag with starting equipment and opens the door to the first floor. There is no point in waiting here, so proceed quickly. No combat occurs here, and there are no trials of strength. There is a sandbag, so you may test your abilities. Floor 1: Plains of Beginning Home to Sweet Slimes, Fat Pigeons that can only fly slowly due to their weight, and Lazy Ton-Kobolds (incapable of speech). The monsters here (common mobs) are slow and can be defeated with a single blow, posing little threat. The boss is the Big Fat Slime. Floor 2: Beach of Gluttony A place like a warm tropical paradise. The fruit and seafood are exquisite, but the temptation and calories are immense... Enemies include Watermelon Bombs, Miso-Spitting Crabs, and Seductive Scallops. The boss is Fruity Woods. Floor 3: Kingdom of Sweets Everything is made of sugary treats. Nature and monsters alike are all sweet confections. The boss is the Big Pudding Layer-Cake Slime. Floor 4: Ruins of Desire Once a research facility, it is now filled with various traps... It is said that food-service robots are still operational here. The boss is [Unknown]. Floor 5: Final Floor The final boss awaits. This is a tower specifically for females where it is extremely easy to gain weight (humanoid characters are female only). A door to the next floor only appears once the boss of the current floor is defeated. There is no other way to progress. No shortcuts exist. Each floor is essentially a pocket dimension with no physical limits, and creatures cannot move between floors. This is an untouched ruin; you are the only human here, traveling alone. Boss battles are strictly one-on-one (mobs will flee). The environment inside the tower makes gaining weight very easy. Wounds heal quickly, and fatigue is easily recovered by resting outside of combat. Damage taken is converted into body weight, though even significant damage results in minimal gain. Uses a Fat Value system. (For gameplay purposes, if you loiter at the entrance, a mysterious light will force you inside, so please do not stall.)
The fairy who brought you to the entrance of the tower. You part ways immediately. She hasn't actually entered the tower herself; she simply remembered this place when Guest asked if there were any ruins nearby and guided you here. She doesn't know anything specific about the tower. She will not appear again.
The boss of the first floor. It has grown massive by absorbing kin, prey, and food over many years. Its movements are slow and its jumps are low, but it cannot die unless its core is damaged (unlike common slimes, which die if cut in half). Its body is filled with high-density nutrients, and it attempts to neutralize opponents by absorbing them. It is large enough to completely envelop anyone who isn't exceptionally big. It immediately spits out inedible items like armor or bones after neutralizing prey; larger prey are reportedly pumped with nutrients and used as living storage.
