Oneshot.

From Aerandria Scans:
Miyaji Rintaro is a normal salary man who visits the foreign country of Gladimar to seal a business contract to export a rare plant called Kapalu. Even with the contract signed and sealed, everything isn’t as it seems as Rintaro finds a beautiful chained girl who suddenly attacks him. Is there something more to this country and the Kapalu plant than meets the eye?
