Sui-ki Shin Megami Tensei III: Nocturne Design

Sui-Ki (スイキ, Suiki) is a recurring demon in the series.


One of the four oni controlled by Fujiwara-no-Chikata. Named after water, Sui-ki can freeze anything to the core.



Shin Megami Tensei III: NocturneEdit

"One of the four oni Chikata Fujiwara was said to have controlled during the Heian period of Japan. He could cause floods with the swing of his arms."
—Shin Megami Tensei III: Nocturne Compendium

Sui-Ki is one 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.

Sui-Ki's hideout is located around a trapped area within the tunnel after going through a pitfall. He presents himself as a cold demon who would leave those who demonstrate courage alone. If the Demi-fiend feigns cowardice, Sui-Ki will attack.

Upon defeat, Sui-Ki expresses curiosity towards the Demi-fiend in his last few breaths, openly wondering if he's a demon or a human.

Shin Megami Tensei IMAGINEEdit

Sui-Ki can only be obtained through fusion. He appears as a field boss on Shinjuku field when summoned by one of the charms the Yaksini NPC in Ichigaya Camp's B11 will trade for magnetite.

Shin Megami Tensei: Strange JourneyEdit

"One of the four oni controlled by Fujiwara no Chikata, it can cause floods at any time. In the Taiheiki, Ki no Tomoo succeeded in expelling the oni by reading a Japanese poem."
—Strange Journey Compendium

Shin Megami Tensei IVEdit

Sui-ki has placed a Domain over a relic on Shinjuku's East Entrance Main Street. Defeating him obtains the Corked Bottle relic needed for the optional main quest Bring Back Wine.

Sui-ki are later encountered as normal enemies in Infernal Tokyo.
