This spell is a part of the ceremony when cadets take an oath to help protecting innocent people from criminals. The ceremony is usually held after the completion of the second term, just before the future guardians go to their summer practice to help preventing crimes.
Today I take the oath to fight,
To carry hope through darkest nights,
Protecting every human being
From the injustice that I see.
Despite the hardship and the pain,
I’ll choose the right and honest way.
Today I swear with all my heart -
I am a guardian of Light.
