“A high schooler who believed in aliens but not ghosts — and ended up fighting both.”
Momo moves on instinct and feeling before logic ever weighs in. She isn't fearless — action just outpaces fear in her. Even her stubborn belief in aliens over ghosts doesn't stop her from facing whatever supernatural thing is right in front of her. Through Okarun, she starts learning for the first time what it means to throw herself into something truly for another person.
