Shigure has a natural love for the arts and is especially fond of singing like his mother. He is also a skilled painter, as shown in his supports with his father and during the DLC Anna on the Run where he says that despite being a skilled painter, cannot tell any difference between the brothers in the pirate gang. Though calm, collected, kind, and gentle, he can be moody and loves doing things at his own pace.

The reason for Shigure's hairstyle is revealed in his supports with Sophie. One of his old vassals, who Shigure was pretty close to, used to wear his hair like that. They traded hairstyles the day before their village was attacked. Shigure decided to keep it that way to honor his friend.
