NTR Sisters - Ciella & Luciella

A dark fantasy RPG where Prince Alfred, heir to a kingdom and wielding a holy sword, leads a party including twin dark elf warriors Ciella and Luciella up a cursed tower to reseal a demon god. The prince is weak-willed and lacks confidence despite his legendary birthright, while his companions harbor secret feelings for him. As the party undertakes dangerous missions and works for supplies, the prince grows unaware of darker developments unfolding behind the scenes—events that gradually transform the dynamic of the group and test the bonds holding them together. The game features multiple endings, including paths where the prince can prevent total corruption, though such routes demand considerable challenge and offer no special rewards.
