理事長に留学生の世話を命じられた大学職員・稜一郎。なんと留学生・カルタカは、
言葉も通じない未開の地に住むネイティブ!! 一族の戦士で超美貌の持ち主だが、
スマホやテレビ、果ては水洗トイレを恐れる彼に稜一郎はうんざり…。
だが、つたない言葉で「リョウイチロー」と呼ばれ懐かれるうちに、次第に心が傾いて!?

University employee Ryouichirou is ordered by the Chairman to take in an exchange student.

That exchange student, Qaltaqa, is a native from a developing country who can't understand Japanese!! Though he is a warrior of his tribe and a man of great beauty, seeing him afraid of the phone and the TV, and even the toilet, Ryouichirou gets fed up…

But while being called "Ryouichirou" in such a clumsy manner, he has a change of heart!?
