Demon Compass

The Demon Compass (妖気計, Yōkikei, literally translated as Demon Energy Plan) is the second of the seven items of Yusuke's Spirit Detective kit.[1]



The Demon Compass resembles a cheap analog watch, but its face is a black ring surrounding a red circle, cut into eight triangular sections, that has an elongated diamond mounted on top of it. Beneath the red circle is a small yellow bar that measures Demon Energy in much the same way as an illustrated vector of a digital equalizer does with sound.[2]

The diamond itself is bisected horizontally, with the top part painted black and has a navy-blue hitodama painted on it, while the lower part remains white.[3]


The Demon Compass indicates how far-away and in what direction an already-identified demon is from the Compass' wearer.[4]


Spirit Detective Saga[]

Botan first used this device to track down Yusuke just after his first defeat at the hands of Gouki.[5]

While using this device to try and find Rando at the Genkai Tournament, Yusuke accidentally broke it because it presumably overloaded itself on Rando's Demon Energy.[6]

Chapter Black Saga[]

Botan mentions the Compass as a possible way of finding Hiei. She claims that it's been modified NOT to overload by using Hiei's DNA as a way to lock on to his Demon Energy and find him that way.[7] But she's discouraged after Kurama casually tells her that he doesn't keep a lock of Hiei's hair on him.
