Besides, the Demon race woman didn't even break a sweat when she reached this floor ahead of the 15 humans. Thinking of how she concealed the signs of combat, it made one fear thinking something laid in wait since they step into the floor, and one would think she had the geographical advantage. It would not be strange if something happen.
The crisis the two had sensed was immediately proven to be correct.
"I see. Then, I won't ask any more. Also let me say this... to invite you is not my main priority, so don't even think of something naive like I won't kill you. Lutos, Havell, Enki. It's time to eat!"
The Demon race woman called out three names and, CRAAASH! Sound of something crushed echoed along with Shizuku and Nagayama's anguished voices when they were blown away at the same time.
"Guh!?"
"Gah!?"
It was not known what blew the two away. With the order of the woman of the Demon race, they sensed the left and right spaces of Kouki's party suddenly blurred. There were "existences" approaching them with speed comparable to "Ground Shrinker," and attacked the unprepared classmates who were watching the conversation between Kouki and the woman of the Demon race.
Even with Shizuku and Nagayama's maximum precaution from the very beginning, they were barely able to notice the surprise attack, and they stood to protect the students who were suddenly the aim of their invisible enemy.
Shizuku was a speedfighter, so her defense is low. Therefore, she drew her swords into a cross towards the blurring space, and tried to jump back to dull the force when she received the impact. However, the enemy's attack power was far greater than she had imagined, so her defense was broken, and she was thrown to the ground, sucking all the air in her lungs. There was even shallow cut on her abdomen.
Nagayama was a "Great Martial Artist," which owned special aptitude towards defense even among hand-to-hand fighter class. He had acquired the skill derived from "Body Strengthening" called "Body Hardening," which was similar to "Vajra," and both skills had great credibility as they were far stronger than a steel shield. Coupled by his huge figure, his hard to break through defend made him suitable to be called a human fortress.
