Toriko no Shirabe -refrain- if Aina no Shou | 虜ノ旋律 -refrain- if アイナの章

Aina Leminen is an exchange student form Finland, attending Seiren Girls' Academy. At school, she is a member of the string orchestra club, and has led a happy and fulling life with her friends.

──Then comes the spring break.

Right after the holidays, Aina travels to a village in the mountains.

Apparently, she is invited to "perform Finnish songs at the village festival."

In that case, the advisor and other members of the club would have to go with her as well, but unfortunately, all of their schedules overlap, so along with her promoter and client, Miyake Issao, they head to the village together.

Despite feeling lonely, Aina is excited for the opportunity to perform the music of her home country.

However......

What awaits Aina is not the festival she has pictured, but a festival overflowing with the desire of men.
