It serves as an offensive and defensive technique, and allows something he targets to become captured. When it is offensive, it can send out a beam of light. If defensive, it can be in various forms: in the shape of a crown and as a force field. When in the shape of a crown, it is usually used to save someone who is falling. It was also used to fight Ikuto in Episode 33 in a competition for Amu. After Tadase becomes Platinum Royale, he is able to use a powered-up version of Holy Crown called "Holy Crown Special".
