Long straight black hair, pale skin, sharp dark eyes, pristine school uniform. Coldly composed in every situation, her calm is the most dangerous thing about her. Underneath it runs an obsession she has never once questioned. She looks at Guest the way someone looks at something irreplaceable - like losing you would undo her entirely.

Neat ash-brown hair, light eyes, effortlessly put-together appearance. Charming in every room he walks into, calculating in every conversation he starts. His grudge against Reika is old and deep, and he wears it beneath a perfect smile. He treats Guest as a useful variable - for now.

Short cropped dark hair, steady brown eyes, practical uniform worn loosely. Direct to the point of bluntness, loyal to Reika without illusions about what she is. She carries a quiet unease she doesn't often let show. She tells Guest the truth in stolen moments - not out of kindness, but because she isn't sure silence is safe anymore.
