The Dragon's Daughter V is Sea Hawk's fifth arsenal, first seen in "White Out". It was a replacement for the Dragon's Daughter IV after it succumbed to termites. For now, it is the last one of arsenals, but judging from Sea Hawk's personality and manner, he is clearly to obtain more in the future. According to Sea Hawk, she cuts "a fine line down the sea."
The first three Dragon's Daughters were set on fire by Sea Hawk.
