Ethereal Enigma

While returning home from his first day of high school, our Protagonist encounters a strange woman who encourages him to make a wish at the shrine. Although skeptical, he unwittingly summons Erilynn, a beautiful yet bold princess from another world. With no idea how she came here or how to send her back, the two must put aside their differences and work together to unravel the mystery.

Now, high school isn't the only thing on our protagonist's mind. He must keep Erilynn's identity a secret while searching for the elusive and mystifying old woman who started it all.
