So Kai really is the more spiritual-driven of the bunch, like the one who I think got the less connections to the material world. From the religious references(so from Christianity, Buddhism and Hinduism ?), to the way he acts so detached and passive, even his blue-ish skin tone.
And concerning his tattoos, I can also see insects? Idk, I’ve also seen that they’ll be important in his route … do they symbolize anything or is it mainly for the horror aspect ?
