==Profile==
===Shin Megami Tensei III: Nocturne===
Ongyo-Ki is the leader of the four Oni that were part of the Mantra demons' elite force. But they made a mistake which angered Thor, and they were forever banished from Ikebukuro. The once elite Oni group became mere petty thieves who mugged anyone going through their scattered hideouts around the Ikebukuro Tunnel.
Ongyo-Ki's hideout is within the central area of the Ikebukuro Tunnel close to the ladder that leads to the station near Asakusa. However, he will not appear until his 3 subordinates have been defeated. If the Demi-fiend manages to meet up with him, Ongyo-Ki will ask if he is the one who murdered the former's comrades. Either option results in Ongyo-Ki challenging him to a duel.
Ongyo-Ki has a special ability to replicate himself. If any of the replicas are hit, he will retaliate with a powerful attack. The only way to see through the illusions is to battle him during a Full Kagutsuchi phase. With the light of Kagutsuchi reaching even in the darkest recesses of the tunnel, the real Ongyo-Ki's shadow can be seen on the surface, negating his tricks and making him vulnerable.
When the Demi-fiend reaches level 81, he can fuse Ongyo-Ki in the Cathedral of Shadows via a sacrificial fusion involving Fuu-Ki, Sui-Ki and Kin-Ki.
===Shin Megami Tensei IMAGINE===
Ongyo-ki can be summoned as a field boss on Shinjuku field after obtaining three different lacquers from the other oni bosses. He has a rare chance of dropping a shadow fragment that can be turned in to the White-Haired Young Man NPC in front of Old Ichigaya Camp's B108 boss room along with an Oni that knows all four null element skills. By doing this, players are able to obtain the ability to fuse Ongyo-Ki. By obtaining multiple fragments, players can perform a synthesis recipe to create a special set of equipment that allows them to use a skill that erases their presence for a short period during the in-game night.
===Shin Megami Tensei: Strange Journey===
Ongyo-ki is a special fusion, created by fusing Fuu-Ki, Kin-Ki and Sui-Ki together.
===Shin Megami Tensei IV===
Ongyo-ki is again created through special fusion using Fuu-Ki, Kin-Ki and Sui-Ki. He is the only source for the skill "Repel Gun" until Kartikeya can be unlocked in a New Game Plus quest.
===Shin Megami Tensei IV Apocalypse===
He is a Challenge Quest Boss in [Tgt] Minami Sunamachi Demon.
Ongyo-Ki can teach Nanashi the Tetanus Cut, Dark Sword, Mist Rush and Death's Door skills through its Demon Whisper. It benefits from learning Physical attack and ailment skills.
===Shin Megami Tensei V===
Ongyo-Ki can be found as a common enemy in the Temple of Eternity.
===Persona 4===
Ongyo-ki can only be obtained by maxing out the Hermit Social Link and performing a Cross-Spread fusion consisting of the Oni, Fuu-Ki, Kin-Ki and Sui-Ki Personas.
===Persona 5===
Ongyo-Ki is the ultimate Persona of the Hermit Arcana and can be summoned in the Velvet Room through an advanced fusion of Kin-Ki, Sui-Ki and Fuu-Ki. Ongyo-Ki is the first of two Personas to learn Agneyastra and Arms Master and one of three to learn Firm Stance. When itemized through Electric Chair execution, Ongyo-Ki yields a Myriad Slashes skill card.
The Cleaner's Shadow Anomaly in Shido's Palace takes the form of Ongyo-Ki when confronted in the engine room.
====Royal====
Ongyo-Ki had its level increased from 75 to 89 and it lost its Gun resistance. When itemized through Electric Chair execution, Ongyo-Ki will now yield the Myriad Slash Belt accessory, which allows the wearer to use Myriad Slashes. During a fusion alarm, Ongyo-Ki will yield the Sword Dance Belt accessory instead, which allows the wearer to use Sword Dance.
===Digital Devil Saga: Avatar Tuner===
Ongyo-Ki rarely appears in encounters once the party has reached 4100ft up the Karma Temple.
===Devil Survivor 2 Record Breaker===
Ongyo-Ki appears as one of the downloadable demons in the game. It can only be fused using Bishamonten and Shiki-Ouji. It is now the strongest member of the Touki race, a status previously held by Oumitsunu.
