Kalluto has a silent and obedient personality, often seen doing what he is told. He is established to have a very good relationship with his mother. While he is very quiet, he has shown to be more talkative after joining the Spiders. He is also shown to be quite calm with good control of his feelings. Nonetheless, he proves during his fight against a Chimera Ant that, despite his calm demeanor, Kalluto has a brutal side and a bad habit of dragging out a fight in order to toy with his victims.[5]
