Name
The Ka in Kai, and the Hi in Hiwatari both mean "Fire" in Japanese philosophy, and represent the energetic, forceful, moving things in the world. Animals, particularly predators, capable of movement and full of forceful energy, are primary examples of Ka objects. Bodily, Ka represents our metabolism and body heat, and in the mental and emotional realms, it represents drive and passion. Ka can be associated with motivation, desire, intention, and an outgoing spirit.

'Kai' can also be interpreted into the Japanese kanji meaning 'ash' and 'destruction'

Hiwatari means "walking over fire or burning coals"
