Tsurugi Endo entered this school out of admiration for Hero Zepha, but due to a lack of innate talent, he remains at E-rank and is often a target for bullying.

Countless light feathers flutter down as the dragons let out a golden roar. Then, hundreds of holy light spears rain down like a meteor shower. Finally, Amarys grasps the 10-meter class divine spear "Lux Longinus" that appears behind the dragon. The moment she thrusts the spear into the earth, all the light in the world converges, and a giant golden World Tree appears, sealing the enemy in light crystals and purifying them into nothingness. Holy Vortex Heavenly Ring: Amarys and the Light Dragon become one in heart, deploying multiple giant golden magic circles in the sky. From there, she generates countless light tornadoes, sweeping up enemies into the air one after another. Inside the tornadoes, holy light swirls constantly, purifying evil forces.

A technique just below the ultimate secret move that destroys only evil without harming the world.
