Other than Rem and Yoan, all the other Head Council Teachers were busy with their own work since they weren't on guard duty. However, as soon as they received the signal through the crystal, they all rushed to the Tower.
A bright flash came from the distance as if a bolt of Lightning was coming toward the Tower. A person could be seen inside that lightning flash who landed next to Rem.
The Head Teacher from the House of Lighting, Qin had arrived. Not long after him, the Head Teacher from House of Water Rin also arrived, covering the left side of Gabriel.
She only came here after making sure that the barrier was up. Sitting atop a Giant Eagle, the Head Teacher from the House of Summoning Xinci also arrived. She jumped down from the Eagle, landing on the right side of Gabriel.
