Ten flying undead wyvers are heading towards Seiki and Silvia, followed by a group of catastrophic orcs running towards the students. Some are consumed alive, while others are crushed to death. Fearing for their lives, Seiki and his friend flee the arena. A wyvern approaches and appears in front of them. A catastrophic orc leaps from the wyvern, and all of a sudden, captain Muji, the first division's captain, incapacitates all of them. Seiki then notices that the deceased orcs' carcasses are slowly decomposing, much like professor Fray's body when he killed her. Then they are ordered to flee immediately by the captain, for they are no match for the monster that lurks within the arena. Seiki and the rest of the group quickly escape, but they don't realize that a group of zombies bats are chasing them. By chance, the imperial knight shows up and launches an assault against the undead. They all choose to aid the knights in their battle against the undead, then Ark appears along with the second-year class B. He immediately unleashes his ultimate skill—the "war cry"—they all gains and increase in their strength, speed, and defensive stats. They are all in shocked that Arc can now cast a high tier skill. Ark's ultimate skill allows them to all completely destroy their undead enemies. Afterwards they decided to accompany the imperial knights in order to aid them in defeating the undead armies. In the center of the arena, Saul and Keil are attack by the remaining ten undead wyverns. Keil then begs for assistance from the Azura kingdom, but they decline, instead they focus on securing their nobles first before heading home. Feeling disappointed by his comrade, Saul advises Keil to concentrate on their enemies rather than pleading with those cowards for assistance. Akihiro unexpectedly shows out to assist Keil and Saul, he unleashes a powerful aura and uses his unique skill, "silent mist," to cover Efrim while he heals all of the injured students on the arena. Saul and Keil are struck by the wyverns' "putrid breath", resulting in them enduring extreme agony and decaying injuries. But Efrim decided to use his divine skill, the "Hand of God," a powerful healing spell that can quickly heal wounds within a wide area. It simply means that it can reach even beyond the arena. Keil and Saul are shocked because this is the first time they have ever seen a divine tier skill that's being casted infront of them. Their body glows and there's an aura that resembles ropes that ties everyone together. Those that are bound by the aura receive rapid healing and ability enhancements. From the flying undead wyverns, the catastrophic orcs and their minions leap and rush towards the students. Following that, Akihiro unleashes his ultimate skill "misty slash" in front of their undead foes, while Muji unleashes his ultimate skill "decaying slash" on the rear of their enemies. After they both vanquish their enemies, the elder brother Muji commends his younger brother Akihiro for having developed into a very strong person.
Once more, a gang of elder lich ambush Seiki and his friends, calling forth their skeletal minions in the process. Then, with the use of their "dark impulse" magic, the elder lich shoot extremely potent dark balls in the direction of the knights. Fortunately, Efrim's divine ability allows the damage they take to heal instantaneously. The knights gain an extremely powerful ability boost with the aid of the ultimate skill "war cry," and they simultaneously cast their unique skills unto themselves "lion's heart" and "increase speed." Their teamwork allows them to overcome the group of elder lich. Along with other students, they all rush towards the arena where they watch the fierce combat between the imperial captain and the catastrophic orc. (A catastrophic orcs are A rank monsters that are wielding a club as their primary weapon, they're capable of using self regeneration and they're extremely powerful opponent). After some time, Victoria has recovered completely and is prepare to fight. Using his first ultimate skill "overdrive" she transforms into her Valkyrie form, and afterwards she activates her second ultimate skill, the dragon killing art "divide" and instantly she obliterates all ten wyverns in one shot. The remaining ten undead wyverns charge towards Seiki and his companion, directing their "putrid breathe" in their position. Apparently, a black metal chain encircles them, protecting them from the impending attack. "Silvia recognizes the chains and she says that Professor Grim is the source of them." Using his ultimate skill, "chain imprisonment," the professor immobilizes the undead wyvern and then summons out an enormous cube prison chains to lock the wyverns. Later, professor Inu makes her appearance while riding her black electric guitar. Professor Grim then tells Inu that he has already succeeded in imprisoning the wyverns together with the orcs. She then plays her guitar while using her ultimate skill, "death note" an invisible notes heads toward the enemies and travels inside their ears. Blood is slowly leaking from the wyverns' eyes, and they are now shrieking in pain. The catastrophic orcs are thudding their heads against the chain prison as though they are in excruciating pain. Suddenly, their heads explode, leaving all of the witnesses shocked and clueless about what had happened. The remaining undead are then all destroyed by Saul and Keil. Seiki is about to go, when all of a sudden the undead's essence starts to fly toward the enormous gate. Slowly, the enormous gate begins to open and a silhouette starts to show. Everyone can only hear the agonized scream of that particular someone as it attempt to pass through the gates. That certain someone is determine to get beyond the gates, but princess Victoria doesn't allow it, she immediately cast her ultimate skill—the dragon-killing art "divide"—and she cuts straight toward the gate with a very strong blow. When her attack hits the enormous gates, it bursts, and smoke is seen all around the gates. Out of nowhere they hear a very cold voice, uttering the word "finally" . The smoke clears, revealing nothing but a stunning, naked, and alluring woman floating into the air. As she gradually approaches the ground, she begins to question Efrim about why she is staring at her in that manner. Seiki then catches sight of the stunning woman's eyes, which he describes as the demonic eyes of lust. He had, in some way, came upon a book in their hideout about a demon general who seduces individuals and leads them to their demise. Silvia tries to stop her brother Efrim from walking towards her, but he ignores her. A terrifying plant with big mouth and sharp teeth slowly emerges from the ground, all of the men are moving slowly in the plant's direction. Professor Inu then used her ultimate skill, "death note". The demon lady is slowly pleading with her to stop while screaming in agony, but all of a sudden, she smiles and laughs. The demon asks Professor Inu if she is aware of who she is dealing with. In response, she confidently states that she does not care and asserts that she is more alluring and charming than the demon. The demon informs Inu that she is one of the demon general "Belial" and she's the embodiment of lust. Then, Inu intensifies the situation: she plays her guitar so loudly that it make her opponent's eyes bleed, but she still senses something is off. She finds it hard to believe that the demon is only laughing at the effects of her ultimate skill. Victoria then launches an attack with her ethereal sword while Silvia casts a unique spell to increase her stats called "ability enhancement." Victoria aims for the demon's throat, but Belial only uses her bare hands to parry the blade. Of all the males, for some reason Seiki is the only one who is immune to the demonic eye of lust. He's contemplating whether or not to assist them when all of a sudden Silvia breaks her brother free from the monster's hypnotic eyes by hugging him, but Belial summons her enormous man-eating plant and it begins to consume the knights. Luckily, commander Tomoyoki arrives and smashes the monstrous plant just as it is ready to swallow the other captains. Then he gives the order for Inu and the others to quickly take the other male students and captains out of the arena. As there are more chaos about to come and all of the sudden, the plant grow again and launches an attack on the commander.
