The Magic Train of Piqmentia Grand Academy that took students to the Alba Mountain Range is currently being surrounded by thousands of monsters. The teachers, principal, and King Leonida fought against the monsters. The teachers looked overwhelmed against the endless wyverns. Kalya who was currently surrounded by dozens of wyverns inadvertently lowered her guard. As a result, she belatedly realized the two-way attack coming at her.

Upon hearing Silphy's scream, Kalya immediately created a double-sided barrier for each attack. But unfortunately, the strength of one of the barriers wasn't enough to withstand the wyvern's attack. The fireball headed straight for her, Kalya no longer had time to dodge or create new barriers.
