If Lisa could see the pure "Long-range Water Needle"—
she would see that Brian was pierced through the heart by a dazzling, dreamlike, beautiful yet extremely fierce and swift blue water needle, before collapsing to the ground.
She would also see that the other two met a similar fate.
One of them was pierced by a dazzling water needle that continued its momentum to strike one among the many magic apprentices.
The other water needle, after penetrating another person, traveled through layers of space and happened to hit the highest point of the Magic Guild's emblem on the roof of Hubert's Magic Laboratory in the town center: a being engulfed in roaring flames, resembling some non-human entity.
—if Lisa and the many magic apprentices present could see the "Long-range Water Needle!"
"Water Magic, turns out to be so dazzling."
Andrew, of course, could see the form of his own magic.
