According to Kuys, he established the Glorious Panda Family about fifteen years ago. It was that time that he was still active as an adventurer and even roamed the Sky Empire
According to him, Sky Empire was pretty big. For example, Sky Kingdom which the Falcon City and Eagle City belonged to was just part of the many kingdoms under the watch of the Sky Empire.
Kuys was not originally a resident of Eagle City. In fact, he only came here around twenty years ago along with his son, Mario.
Ban just realized that Boss Mario and Kuys were actually related. However, he hid his surprise and listened intently to Kuys story.
Fifteen years ago, Mario adopted a boy he found in the slums. The boy was quite cheerful and active, and aimed to become a strong powerhouse in the future. However, the Beast Tide occurred, and due to some unfortunate event the boy and his dreams were buried along with the Beast Tide.
