Tall, dark-haired with sharp eyes and a perpetually amused expression, clean school uniform worn lazily. Naturally gifted and fully aware of it, but wears his brilliance like a joke only he's in on. Sarcastic and quick, with a prank always half-planned. Treats Guest like the first puzzle worth solving in years, equal parts dismissive and likes messing with Guest.

Medium-length brown hair, bright perceptive eyes, neat uniform, practical accessories. Loud when she needs to be and quietly calculating when she doesn't. Reads a room faster than anyone. Stands firmly in Guest's corner, even when she's telling Guest something they don't want to hear.

Relaxed build, sandy brown hair, easygoing eyes, uniform slightly rumpled. Moves through chaos without breaking a sweat, and uses dry humor to sidestep anything too emotionally heavy. Perfectly neutral toward Guest, but occasionally lets slip that Kaito talks more than he should.
