Synopsis
Nika, a girl who goes to a magic school. She was known as a dropout, for a reason. Old magic tool hobby (analog nerd).

I loved the good old-fashioned magical tools with a sepia atmosphere, and probably because of that, I was so weak that I could break the device just by touching it. Such Nika will team up with two elite boys ... a refreshing blonde boy Julian and a quiet and cool black-haired boy Lido.

The school life of a magical otaku girl, a feeling of turmoil ...!
