For some reason the names of the heroes are displayed as symbols. I haven't found a solution yet.

Mio is an ordinary female student. She has an amazing past, where she saved another world one year ago by taking on the body of a futanari.
Living peacefully in the present day, she meets her childhood friend Luka for the first time in 10 years, but fate shakes her once again.
To her surprise, she is reunited with Seira, a saint who appears from another world.
Seira had appeared to stop invaders from another world who threaten the modern world.
In order to protect peace, Mio once again stands up as a brave warrior with the holy sword Futanari!
