The Tres Kantos is an all-male trio composing of three journalists. They show themselves, on the latter part of the series. Initially reporting about Juan as the Anak ng Dilim. The three boys later helped Juan to find the gem of humans and broadcasted to the masses to pray for Juan.
Actually, they are all originally members of the kapatiran, disguising as a techie- nerd guys. No one was even aware of this fact maybe not until they reveal their true identity.The reason behind their cover is anybody's guess.
