Being an orphan, Kakucho is generally closed-minded and finds it hard to trust others. His trust in Izana is unconditional, his self-proclaimed "master" since childhood, due to their mutual experiences as orphans who met and grew up as brothers in the same orphanage. His loyalty to Izana is demonstrated by his willingness to confront any of his enemies, or anyone who considers the two of them enemies, making Kakucho one of Izana's most loyal servants.
