Upon the incoming hit from opponent, defensive mana is concentrated at the hit-point and offensive mana is used to rebound the attack. This instant defence is considered a risky move, despite its toughness which may even free Vivio from all damages if she can fully detect the incoming attack. Mikaya Chevelle comments that it is similar to a pinpoint barrier (like Subaru Nakajima's application of Protection in StrikerS episode 15), although its rebounding effect sounds like a function of shield-type defensive spells.
