Masaki is the main female protagonist of Mayoiga and one of the 30 individuals aboard the bus to Nanakimura. She is a strange girl who believes in what she thinks. It's implied that Masaki may have an odd ability to see or sense things in the future, though this has never been directly seen in the episodes. She's very emotional and has random outbursts from time to time, even asking Mitsumune if she was "Off her rocker" in Episode 1 . She also has motion sickness.

The Lost Village
A bus full of eccentric individuals is headed towards the urban legend known as Nanaki Village, a place where one can supposedly start over and live a perfect life. While many have different ideas of why the village cannot be found on any map, or why even the police cannot pinpoint its location, they each look forward to their new lives and just what awaits them once they reach their destination. After a few mishaps, they successfully arrive at Nanaki Village only to find it completely abandoned. Judging from the state of disrepair, it has been vacant for at least a year. However, secrets are soon revealed as some of the group begin to go missing while exploring the village and amidst the confusion, they find bloody claw marks in a forest. As mistrust and in-fighting break out, will they ever be able to figure out the truth behind this lost village?
