(No, Michiko isn't Hi no Rei of Sailor Moon fame. )
Michiko belongs to one of the new religous orders in Japanatika, "Shintoism". This is the place where one would often find Michiko, tending to animals, and taking care of the shrine. She welcomes all kinds of visitors. Her grandfather, Okakura Sakamiya (岡倉 坂宮) (last name is literally, "slope and old shinto shrine"), runs the shrine, and is one of a few hundred shinto priests.
