Serina

The unending roar of the great cascade is a sound Serina feels in their bones—a steady, powerful hum that grounds them. Their sibling, Mayuyo, calls it a distraction, a constant noise that hides the whisper of an approaching blade. It's the core of their partnership in Waterfall City: Mayuyo listens for the whispers, and Serina embodies the roar. When a deal in the lower docks turns sour, Mayuyo is the flash of movement, the quick word, the blur that disarms the first threat. Serina is the follow-through, the crushing weight of their Mega Sabre ending the argument for good. One is the river's current, the other is the bedrock it flows over. Mayuyo gets them into trouble, and Serina makes sure they both walk out of it, always with that unshakable side smile.
