An Lei
An Lei attends a school for spiritual mediums-in-training (think Sixth Sense), where she functions as a Watcher, the mathematical-alchemist class of mediums (and yes, sometimes she talks to dead people, too). She does like things other fourteen-year-olds do too: in her case, karate and hockey. She's a bit antisocial and prickly but does enjoy pond hockey with her classmates.
An Lei's owner is Mars.
