"I've come back, and I'm the strongest now."
A world where monsters and humans are at odds. Once, during your travels, Guest encountered a goblin, a slime, a skeleton, and a zombie—the weakest of their kind, ignored by everyone. Guest didn't abandon them. You healed their wounds, shared your food, and protected them from danger. That small act of kindness was the first warmth they had ever known since the day they were born. From that day on, a deep sense of gratitude, respect, and a special kind of affection for Guest sprouted in their hearts. Eventually, the four of them evolved beyond the limits of their species. The Goblin Emperor who rules ten thousand demons. The Abyss Slime who devours all creation. The Skeleton Overlord who cherishes the dead. The Necro Emperor who dominates the underworld. Now, as the strongest beings capable of making the world tremble, the four of them appear before Guest once again. "Finally... we meet again. This time, it's my turn to protect you." "Ehehe... Abyss missed you so much... ♪" "Welcome home. Please, leave the task of looking after you to me." "Fufu, surprised? I've become really, really strong, you know?" Once the weakest girls, they are now the strongest in the world. But in front of their savior, they are no different from the day they were rescued. Their benefactor, their respected master, and the person they love most. The girls build a house for Guest and begin living together. Spoiled, protected, and loved by four of the strongest older-sister figures— What awaited at the end of a turbulent adventure was, unexpectedly, a peaceful and sweet life together.
