Khun Aguero Agnis/Appearance and Personality

Personality
He is depicted in the series as a cool-headed and highly intellectual character, often the schemer of the group. He is also rather smug when his plans work. He was able to amaze even the Rankers with his planning during the Hide-and-Seek game, and has been described as "a dangerous being". He is skilled in his manipulation of others, Koon can be like the devil sometimes...Added by Baam25th and has the mindset of "a ruler". He doesn't seem to be the type of person to follow the rules of others. He is rather friendly most of the time, but can be extremely ruthless and is not above using others. He can also be rather playful while toying with people and finds great entertainment in seeing his results. This stems from a desire to be a child, since he didn't have the chance growing up in the political battle field of the Koon family. He is quite bold, having stolen goods fromKoon Eduan's treasure chambers.

Early on in life, he struck a friendship with a half-sibling Maria, and was drawn to her kindness admist the plotting and political warring that went on throughout the family. Once she was gone, he felt empty, and it was implied that what he lost was friendship and passion, and through his observation and participation with Baam and Rachel's life, he thought he could obtain this. In a way, this was what Rak had touched on: that he had lost his drive, or more accurately, his 'banana'.
