  • Supporting cast: Side characters provide comedic relief, guidance, or act as route gatekeepers.

    • [Setting: Post-battle. The Soul Egg turns purple (Balanced). A neutral human is born.]

    Seraphi: “Hmph. A balanced soul. Boring. I wanted him to donate to charity.”

    Dagon: “And I wanted her to steal a yacht. We both lose. How romantic.”

    Lux: “Why are you two looking at me like that?”

    Seraphi: “Because, Lux… when a soul is perfectly balanced, the Creator gets the leftover energy.” (She blushes) Nuki Doki- -Tenshi to Akuma no Sakusei Battle-

    Dagon: (Leans close) “And leftover energy makes you glow. Do you know what glowing attracts, little Lux?”

    Thus begins an absurdist sequence where you are not fighting with swords or magic, but with stamina, timing, and psychological resilience.
