“Thrust and feast, Thirteen Fangs!”

The whirlpool of Magical Energy felt almost like an underground cyclone. Though it was incredibly small in size, the magnitude of the winds was comparable to that of an actual windstorm. The Magical Energy sliced through the roof of the cavern and began to spin in the opposite direction, slowly converging inside the “lance”.

No matter what we had up our sleeves, it was too late. The words to unleash its name had already come from beneath the mask.

“Rhongo—”

In the instant when she was about to unleash the full power of the Noble Phantasm, I heard a small cracking noise.

We did not make that noise. It didn’t come from Bersac and Illumia, who had been fighting before then, or from the large amount of bone soldiers.

It came from a corner of one of the walls of the cavern.

This sound, which was incongruent with the Noble Phantasm that was about to be unleashed, attracted our attention.

Father Fernando stood there, staring blankly at that corner of the wall as a [crack] appeared there.

The crack grew quickly, bringing about a strange rumbling and and unexpected phenomenon.

Torrents of water gushed in from it.

“A mountain flood—!”

“Haha, it’s ‘cause of the swamps nearby, isn’t it? The lance’s power had already loosened the dirt around here, and it’s completely collapsed now, huh?”
