Daisaku is a gentle giant. One of his most notable quirks is him making up his own sayings such as "the strawberry seed only shows its face three times", but no one has any idea what they mean. Daisaku himself admits that they don't mean anything, he simply enjoys saying them. While his voice has been described as "creepy" by others as it's more feminine than his build suggests, it doesn't seem to bother him and even thinks of it as a compliment He also dislikes violence.
