Tengu are a species that originate from Japanese mythology. Those who became tengu and had ignorant or cruel hearts would become ko-tengu (small tengu) and those that were knowledgeable would become dai-tengu (big tengu). The koppa-tengu or "leaf tengu" are among the smallest of the kotengu family, possessing very little spiritual energy. It is sometimes said wolves that live an exceptionally long life will become koppa-tengu and later will change into a form closer to a Karasu Tengu. The koppa-tengu often act as retainers and messengers to larger tengu, especially the tengu king: Sojobo, a kurama tengu.
"A type of Tengu, the supernatural form of a wolf that has lived to an extraordinary age. Like Karasu-Tengu, they appear as mountain priests and act as menial servants to other Tengu. Unlike Anba-Tengu and Karasu-Tengu, Koppa-Tengu have no great supernatural powers, but their huge wings allow them to soar freely through the sky. They are clever but cowardly, rarely appearing before humans and traveling silently in groups at night. Among the many different types of Tengu, Koppa-Tengu serve as the messengers. They use the elements of small birds for this purpose."

Koppa Tengu can be found as a common enemy in Tennozu. As with the other tengu, Koppa Tengu is also tasked with finding Amanozako.
One Koppa Tengu can be found in Tennozu Isle and initiates the quest "Birds of a Feather," requesting protagonist, requesting a giant bird's feather to make a crown to become stronger. After the protagonist returns with the feather, he realizes he made a mistake in not getting it himself but rewards them for their efforts.
An enemy Koppa Tengu can be spoken to by Amanozako, resulting in humorous dialogue in which she terrifies him, but he gives her an item nonetheless. If in the protagonist's party, he may also speak to an enemy Kurama Tengu and reveals he accompanies the protagonist to grow stronger, prompting the senior tengu to give him an item to help him in his training.

The scroll hanging before Koppa is "tora no maki" (虎の巻*)? which teaches secret techniques and is meant for senior disciples within the school. So ironically Koppa would be too low of its rank to get hold of such scroll. The term is borrowed from the Tiger chapter (虎韜, hu tao) of the Six Secret Teachings (六韜, liu tao) which detail military strategies from the Chinese Zhou dynasty. In modern day Japanese, "tora no maki" is borrowed for "cheat sheet," especially commercial publications which claim to improve school students' performance in examinations.
Koppa Tengu is the only Temperance Persona in the Persona series with a weakness to Bless skills.
