Shaula:  “Ah! You came, Master?! I’m so glad! Come to see my big performance? Or more like an office visit! It’s bring Master to work day, so please enjoy!” Shaula responded with a cheerful voice that was entirely at odds with the situation.

The moment the beams made contact with the sands, the ground was consumed by massive explosions. The demon beasts running furiously across the sands were no safer, splattering blood and flesh everywhere as they exploded, too.
