Sergio is an elite with the ability to manipulate the rain. However, he is only able to start a storm and is unable to control or stop it once it starts falling. When Sergio was with the Dagger Society, they gave him the name of Rainmaker. This name is then used again when he joined the Rose Society.
Biography
Not much is known about Sergio before he joined the Daggers, except that he worked on a ship as a rigger. When he was eighteen, Raffaele came to him to convince him to join their side. He immediately refused, but when Raffaele brought him to dinner where he and Enzo demonstrated their powers, and brought out a bag full of gold talents his opinion immediately changed. However, his powers did not appear for months and eventually he caused a terrible drought in Estenzia. Desperate to prove his worth, he tried calling upon the rain in the middle of huge markets and in public without any luck. Raffaele demanded Enzo to kill him immediately, fearing he would disrupt their plans. Enzo instead knocked him out with the tip of a poisoned blade, sparing his life and shipped him off somewhere else, leaving only a short note. Sergio has since then held a grudge against the Dagger Society, and is eager to ruin their plans when Adelina suggests so.
Some time after the Daggers abandoned him, he joins the Night King as one of his mercenaries and eventually learns to control his powers. The Night King finds him useful, helping to steal from other ships and conquering pirates that try to steal from the Night King. His group of mercenaries become a part of the Night King's private fleet, and the ship that they yield is called Double Edged Sword.
After Adelina's murder of the Night King, he realizes her powers and offers her his assistance to get out of Merroutas. It is when Sergio conjures up a storm to help them get away that Adelina realizes that Sergio was the young boy Rafaele spoke of, the boy who could not control the rain. Sergio and his Mercenaries pledge their alliance to Adelina and the Rose Society with the promise of a fortune, and along the way he grows close with Violetta.
