Description
The user turns their arm into a large spearhead, from which a large number of steel spears are fired towards their enemy multiple times in rapid succession. In the anime, the attack is sometimes portrayed with the user extending one arm towards their target's direction, with the fingers outstretched, and then summoning their Magic Seal in front of them, from which the spears are fired.
