Extreme Clash of Ultimate Strength (Moon Tickets, Please)
'Gale Sword Emperor.'
Hearing this title, surely anyone would be able to guess what Kurogane Ouma's ability was.
"Wind."
Kurogane Ouma was a natural-interference-type ability user of wind—in other words, a wind mage.
At this very moment, what Kurogane Ouma was using was the most common and widespread Blade-Breaker Technique among wind mages—'Vacuum Blade'.
As its name suggested, it was a slashing attack used to tear through the atmosphere and create a vacuum in the air, turning wind into blades to attack with.
Although this Blade-Breaker Technique did not possess particularly high power, it had extremely potent killing force. Its speed surpassed the speed of sound, and because it could not be detected by the naked eye, it was difficult for enemies to evade. That made it an incredibly practical Blade-Breaker Technique.
It was common and widespread not because it was unimpressive.
On the contrary, it was precisely because it was so useful that wind mages all chose to master this Blade-Breaker Technique, causing it to become common and widespread.
Thus, when Kurogane Ouma slashed out a blade of vacuum wind, the atmosphere howled and trembled. A hurricane swept over the heads of the people lying prone, swept across the space before Luo Zhen and Edelweiss, and landed on the tree-lined path beside the campus.
"Boom!"
Amid the thunderous roar, the vacuum slash traveling faster than sound severed the entire row of trees. One tree after another was sent flying into the air before crashing to the ground and kicking up clouds of dust.
"He attacked without even saying a word...!?"
Todo Touka's expression turned grim.
"He's serious! Everyone, summon your Devices!"
Though Stella Vermillion was still in confusion, her exceptional combat instincts allowed her to quickly grasp the situation.
