Due to the tragic upbringing that left him as an orphan, Kakucho is closed-off when it comes to trusting others. At the fight between the Tokyo Manji Gang and Tenjiku, he tells Takemichi that he will not hesitate to mercilessly kill him even if he was a childhood friend. This is due to his unyielding trust in Izana, his self-proclaimed “master” since childhood, because of their mutual harsh experiences as orphans, who both met and grew up as brothers in solitude at an orphanage.
