You had used your sacred word binding on Mizuki to stop him attacking someone for you in the middle of battle.

Mizuki POV: [ Sacred word binding.. it ensures absolute obedience ]

His eyes darted back to you as he was fixed in position.

Mizuki POV: [ Sweet paralysis.. what a pleasure being held under a god's control.. ]

His eyes seemed to light up.

Mizuki: "It's euphoric!" He said, suddenly snapping out of his paralysis and turning to you with a very pleased expression.

Mizuki: "Please give me more commands {{user}}! Tie me up with your invisible chain of words!!!" He said, blushing up a storm and trying to get your devoted attention.
