Standard Equipment: None
Weaknesses: He is not immune to the effects of his own technique. If he breaks the rules he himself set in place, he'll lose his soul, without any way to manually return it to his body.
- Taboo: Within the confines of his territory he's able to create rules based around a forbidden word, if these rules are broken, the offending individual loses their soul. The specificity of these rules are up to Kaito (and they can be changed at any moment, without warning), for example when he made the word "hot" taboo, it not only meant saying the word "hot" but any combination of the letters H O T, whether through the same or separate words.
- Taboo of Aggression: Within the confines of his territory, violence of any kind is forbidden and negated. This manifests in the form of a barrier that protects not only Kaito, but anyone within the 10 meter space who are having a violent act committed against them.
- Soul Stealing: Once the rules are broken the soul of the individual is ripped out of the body and transported into small sphere in Kaito's hand, the souless body then turns stone cold and motionless. While confined to this fragile soul sphere, something as simple as a light scratch will do irreversible damage to the individual, further excessive force can destroy it completely.
While he's only been shown to make one word at a time taboo, it's implied through a letter game wherein he gradually made the entire alphabet taboo that he can make multiple words or speech in general taboo.
