Murillo received the highest combined scores culled from the judges' ratings and the number of text votes, beating out six other finalists of the talent show.
He will take home the P1-million cash prize and be part of a boyband managed by Star Magic.
Four more winners, each of which will also receive P1 million and a contract with the ABS-CBN talent agency, will be announced on Sunday to complete the group.
For his finals performance, Murillo sang Major Lazer's "Cold Water" with Russel Reyes.
Judge Aga Muhlach praised Murillo for his vastly improved confidence, while singer Yeng Constatino reiterated that he is one of the strongest singers in the competition.
The other grand finals performances were Joao Constancia, Mark Oblea and Ford Valencia singing Enrique Iglesias' "Bailamos," and Tony Labrusca and Tristan Ramirez covering Bruno Mars' "Treasure."
Voting to determine the remaining four winners will resume tomorrow night.
