The original personality of Tohka Yatogami, who was born from the crystal of Sephira Malchut. Also known as Inversion or Dark Current. Shadow awakens and captures Tohka's body if Tohka is exposed to the strongest influence of negative emotions. In the past, Woodman founded DEM together with Westcott and Ellen. They summoned the First Spirit in the world, and unintentionally caused the first spatial quake to occur. However, Woodman claims that he adores Mio at first sight; realizing Westcott's disillusion goal causing Woodman to abandon DEM and formed Ratatoskr. At first, he was unwilling to resort to using Shido's power to seal the Spirits' mana inside his body for his goals, believing nothing good will come out of storing all that power in a single person. Yet, he was unsuccessful and theorized that a Sephira Crystal can only be extracted if all currently known Spirits have their mana stored into a single individual. Eventually, he was forced to use him as there was no other solution found. Spirits are extraterrestrial beings whose arrival is usually preceded by a spatial quake. These spatial quakes are usually involuntary, but they can also cause spatial quakes voluntarily. Each Spirit has a unique ability, and each displays different levels of knowledge about Earth. It is later revealed that the source of a Spirit's power is a gem known as a Sephira Crystal. When a human is exposed to a crystal, they receive whatever power the crystal stores inside.
