Most of the time, even in serious situations, the Captain might speak about bananas. Despite this, the captain is someone who will lend his help to all, unable to ignore those in need regardless of what he says. He is stated to be someone who respects Evelysse and Coro, who in turn rely on the Captain.
The captain has gender-neutral dialogue in the Japanese version, however some events characters refer to the Captain with male pronouns, for example Verda asks if she can refer to him as her "big bro" when she joins the crew. He sometimes has fantasies of women when asleep or otherwise unconscious, as seen in Planet of the Deep Blue Sea or Memory of a Bouquet.
