Kurama Tengu (鞍馬天狗) are the most powerful and well-known of the Japanese Tengu who were said to live in Mt. Kurama in Kyoto. The Kurama-Tengu are not only said to be exceptional warriors, but also have the ability to fend off disease and bring good luck.
The king of the tengu, Sōjōbō (僧正坊), is one of the Kurama Tengu, and in the 12th century was said to have taught Ushiwakamaru, the future famous warrior Minamoto No Yoshitsune, the arts of swordsmanship, tactics and magic.
Kaneko's human-like design for Kurama Tengu draws inspiration from Jirō Osaragi's Kurama Tengu, from the eponymous novel Kurama Tengu, later adapted into film in 1928. Kurama Tengu wears the attire of a yamabushi (山伏, "mountain hermit") which is said to be the basis of the mythical Tengu. He can be seen blowing into a horagai conch and wearing distinctly Jewish accessories like a tefillin and kippah. This deviation is believed to be an intent to infuse the Japanese-Jewish common ancestry theory, despite lacking official clarification.
Shin Megami Tensei III: Nocturne
Kurama can be only obtained by evolving its predecessor Karasu and is one of the few demons in the game that can only be created via secondary evolution. Even though Karasu can only be created by evolving a Koppa, Karasu can be encountered in normal battles and persuaded to join. Therefore, it isn't necessary to begin with a Koppa to ultimately obtain a Kurama, but some of Koppa's skills will be missed if that step is skipped.
Kurama Tengu can only be acquired through fusion, though variations appear in Shibuya's Celu Tower gold level instance. In the Mount Kurama instance accessed through Nakano, he is a central NPC and final boss for all levels. By gathering cords from the endchest, players are able to fuse a more powerful Kurama Tengu that learns a unique almighty spin move.

According to Kazuma Kaneko's Work III, the namesake media franchise Kurama Tengu by Jiro Osaragi (大佛 次郎) with its original novel premiered in 1924, in particular the 1928 movie adaptation starring Kanjuro Arashi (嵐 寛寿郎) has been influential to the public perception of the mythical entity. The protagonist who is a loyalist-activist assumes the "Kurama Tengu" persona to carry out his vigilante missions. This explains why Kaneko's Kurama Tengu lacks the symbolic elongated nose as the famous statue erected in Mount Kurama, Kyoto.
In the debug mode of Shin Megami Tensei III: Nocturne, there are two leftover beta cutscenes featuring the Demi-fiend, Chikatilo (ティカティロ?) and Izuna (イヅナ?) with the latter two using the models of Incubus and Kurama Tengu respectively. Izuna's mannerism is reminiscent of the Chaos Hero for his ruthlessness. On a side note, Izuna using a Tengu model is probably based on Izuna Gongen (飯縄権現), a Japanese folk god of amalgamation who takes the form of a Karasu Tengu while riding on a white kitsune/fox.
Kurama Tengu's 3D models differ slightly between Persona 5 and Persona 5 Royal with the latter incarnation features fewer facial details, resulting a younger looking Kurama Tengu.
