フレデリック＝ロゼ＝ランフォード

"You damn pirates! I'm going to catch you today for sure!"

Captain of the seventh team of special anti-pirate forces in the Guardia Navy.
The eldest son of the noble Rumford family.
He's quite aware of the fact that he looks younger than his age and gets angry when it's pointed out.
The fact that he's assigned as the leader of a special team at his young age is more because of his own effort than the fact that he's a noble.
