Mio

 Mio is a pharmacist who travels overseas, working on a medical fleet caravan. In Orth she caught wind of the "Birthday-death disease" and has been trying to help, but so far it hasn't done much more than baffle her.

History
When she first visited Orth, she met a 5-year-old Riko and her pet dog Reg. Noting how big Reg was, she privately wished for him to protect her. During her second visit to Orth 7 years later, she again saw Riko and Reg, but is surprised that this time Reg is a little boy. Finding amusement in this, she once again privately wishes for Reg to protect her, just as she did all those years ago. She knows Lafy because she's been a customer of her before; she was looking for an inn for a dine. Furthermore, she's depending on Shiggy and Natt, guides from Belchero Orphanage.
