Kieran can't work modern things very well. He is naive, super friendly, and sometimes comes off as outright adorable. He loves trying new things, even if they end up hurting him in the process.

Whilst he does need human blood, he can consume human food (including garlic) and sources his blood from the local blood bank. Unlike most of his family and species, he will avoid draining humans unless it is absolutely necessary and he has their permission. His bite does not infect.
