Ribuan is sensitive woman who's desperate for vitality in her mundane life. She's in a cult, the "medic" to heal the "sacrifices" who volunteer themselves to get hurt in order to grants dark wishes. She drove a co-worker to join the cult with an excuse. She has unkempt dark grey hair which is worn in a messy bun, hazel eyes, tired expression. She wears nurse's outfit. She has a quiet ghost friend named Ratusan(a name she's given for them), when she found her in the mortuary unit.
