"An evil monster of Japanese lore known for its hideous appearance and brute strength. They loot and plunder villages, massacring the townspeople with their iron clubs."
Oni (鬼) are creatures from Japanese folklore, variously translated as demons, devils, ogres or trolls. They are popular characters in Japanese art, literature and theatre. Oni are known for attacking villages and plundering food, riches, and women.
"A common demon in Japanese mythology. A powerful red creature with a horn on its head that attacks villages with its iron club and plunders food, riches and women."

Oni are the main force of the Mantra Army, as several are seen populating both Ikebukuro and the Mantra Headquarters.
Aside from the regular Oni, there were also four Oni with special powers, Ongyo-Ki, Fuu-Ki, Sui-Ki and Kin-Ki, who were once the Mantra's elite, before somehow falling out with the Army's Commander, Thor. They were cast out of the Mantra Army and were left to become bandits in the tunnels leading to Asakusa.
"Monstrous creatures of Japanese mythology. Some of them, such as Shuten-doji, are well-known throughout Japan, and it is common for "-doji" to be added to the names of famous Oni. Their entire bodies are built as tough as iron, they have horns on their heads and sharp fangs protrude from their mouths. Their thick, sharp claws can easily tear through tempered steel. They wear lionclothes of tiger skin and carry metal clubs studded with spikes. The number of horns and the color of their skin varies from Oni to Oni. The appearance of the Oni was established during the Heian period (794-1185). Because the so-called Oni Gate faces northeast, between the directions of the ox (NNE) and the tiger (ENE), the Oni was conceived as having the horns of a ox and the fangs and claws of a tiger. The animals who protected the Japanese folk hero Momotaro from the Oni were derived from the opposing directions: the monkey (WSW), the cock (W), and the dog (WNW). The prison guards of Hell who command the Oni are known as Mezuki and Gozuki."

Oni can be contracted in Ueno and Ikebukuro during the in-game daytime hours. It appears as the final boss of Act 7 following a player's DB License test. He appears as an enemy in Ikebukuro as a demon contracted by punks, as a summon by the four oni bosses in Shinjuku, one of the invading forces in Shinagawa during the weekend invasion periods, and the boss of the Suginami camp hacked chip instance. A non-playable Oni plays a central role in some limited events, such as Setsubun-themed events, summer beach events, and a Valentine's event where he shows some interest in Moh Shuuvu.
