Iku Iku Succubus [Final] [Orcsoft]

Not present anywhere in the Human Realm,
the Succubus Kingdom is located in an entirely different world known as the Dream Realm.
This begs the question: why are there study abroad students from another world attending a university in Japan?

His responsibility as an instructor is to teach the foreigners about the Human Realm…
On paper, at least. However, according to the program’s director, Lima,
his true objective is to rehabilitate failed succubi, and the two delinquents he’s in charge of will surely be a handful.
