The dumb Amazoness didn't even question what she just saw and simply said, "Please teach that to me!"
"Well, it's a pretty advanced technique. Without proper control, knowledge or capacity, it's impossible to pull off something like that," replied Kisuke.
Those who normally take the vanguard position became very interested in Ki, however, the same couldn't be said to those who normally take the rearguard. They're more interested in how to counter something like that.
If this were to be widespread, their position would be in jeopardy as many people may be able to easily counter them, which in turn, increases the risk to their lives.
Of course, Kisuke knew that not everyone had an affinity with Ki, so as to not widen the gap between Magic and Ki, Kisuke planned to introduce more usages for Magic and break their doctrine that Magic could only be used the way they're currently using it. In other words, breaking their common sense regarding Magic.
"Now then, before we continue, let me add a few things for those who're making sour faces."
Hearing that, Lefiya's pouty face froze and tried to revert her expression to normal. However, her failed attempt only made her face worse. Chuckling at that, Kisuke continued, "It's not just Ki that can do this trick. Magic is also capable of doing so. Moreover, although not specialized for body reinforcement, Magic can also strengthen your body actively."
Of course, as Magic users that are more focused on their Magic parameter and are assigned to deal devastating blows to enemies, they doubt if they could really strengthen their 'frail' bodies.
Guessing their thoughts, Kisuke turned to Serafall and said, "Sera-chan~! These people don't know the true potential of Magic. The most important thing for them is their Magic's firepower. They don't even know how to walk on water despite knowing how to 'use' Magic."
Serafall, who was having a fun time with Sona while ignoring most of the things that were happening because it had nothing to do with her, immediately reacted, "Huh? The most important thing is firepower!? And they can't even walk on water!? Just how poor is their control!? I didn't expect such an infuriating group would exist!"
Since Kisuke and the rest hadn't explained the nature of Magic in this world to Serafall, she didn't know that people of this world depend on chants to control and materialize their Magic. However, even if she did know, she might have said the same thing.
It's true that controlling Magic Power in this world is hard and risky, but total control is not impossible. Just depending on what was given to you, it didn't bode well with Serafall, who even though she had an enormous amount of Demonic Power and could cast Magic through just her imagination, it didn't stop her from studying other systems of Magic, including Holy Magic even if she couldn't use it.
However, Serafall's words hurt their pride that even Riveria couldn't help but furrow her brows, "We're Adventurers. Although we know the importance of versatility in Magic, pure firepower could overturn the situation in the deeper floors, hence it's much more important. How would you defeat hundreds or thousands of monsters besieging you if not with firepower?"
Serafall wanted to refute her but managed to stop herself and simply sigh. Just from Riveria's reaction, Serafall figured that they hadn't met an enemy that could reflect Magic attacks. Pure firepower attacks are indeed effective, but only if the conditions were optimal and you wanted to finish off weakened enemies.
Unless one has special properties in their Magic attack like Sirzechs', it's a basic thing to prepare defensive or reflecting spells against large scale attacks. Moreover, destruction type spells were heavy for Magic Power consumption compared to Bewitching or other crowd control spells which are generally harder to counter due to their variations.
And if you're really besieged, saving your strength is equally important as finishing the battle quickly.
Sighing, Serafall replied, "I won't argue with you anymore since I also don't know what the Dungeon has to offer."
But immediately after, her cheerful expression returned and added, "However, I'll still demonstrate you some nifty magic tricks~!"
Riveria, however, was getting a strange feeling. It's as if a veteran is trying to tell her that she wouldn't understand unless you experienced it yourself.
Meanwhile, Yoruichi approached Kisuke and asked him if this is fine, "It's fine~ She knows she can't show anything powerful."
While receiving doubtful looks from the rearguard members, Serafall continued walking until she stepped on the water. Similar to Kisuke, she kept herself afloat, "I'm doing the same thing as he did, but instead of Ki, I'm controlling my Magic Power to keep the state of the water below me. However, this is a pretty advanced technique and it's a lot easier to just use Elemental Magic."
After her explanation, the water below her slowly froze, without her doing anything evident.
The Mages became wide-eyed seeing this as they couldn't even tell when she cast her magic, nor could they feel the disturbance in Magic Power which is very normal when a spell is being activated.
Disregarding their reactions, Serafall continued walking while creating ice on her path until she stopped a few meters away from the shore, "Of course, this isn't just limited to Ice Magic, as you can use Water Magic to condense and solidify the water itself."
As she took another step forward, instead of ice, under her feet were vortexes, "You can also use Wind Magic to keep yourself afloat, but if it's Wind Magic, you'd rather have just propelled yourself."
As she finished her words, the wind suddenly gathered and gushed around Serafall, before she suddenly shot up to the sky, hovering midair and looking down on everyone with a bright smile, "Well, these are just a few things you could do with Magic~! In a real battle, you can use these to reposition yourselves to more favorable terrain~."
"S-she's flying..." Muttered Lefiya.
"...Even Ais-san couldn't stay that long in midair," added Alicia.
"More importantly, I didn't even hear her chant a single word to do all of that... How was that possible? Is it because of a rare skill?" asked Elfy, Lefiya's roommate.
With a bitter smile, Riveria shook her head, "No... That wasn't a rare skill. After all, Kisuke was also capable of that. You should have seen Sona, Aika and Koneko cast their spells. They didn't mutter a single thing, and I don't think only they are capable of this in their Familia. You know how unlikely it is for individuals to have the same skills, right?"
She then smiled and looked up to Serafall, "She said that firepower isn't the most important thing against a large number of enemies. I wonder what she knows to strongly believe that isn't the case? Either way, I want to know more and if you want to do the same, you first have to throw away your notion of Magic and even those I taught you in the past."
Anakitty understood her stance immediately and said, "Riveria-sama is admitting defeat?"
The first time she witnessed something like this, Riveria thought that Kisuke was someone special. However, after seeing such usage of magic from many individuals, Riveria already accepted that he isn't unique. In that case, she really knew nothing about Magic and only now could she accept it.
Hearing that, Serafall smiled slightly and continued, "Now then~! To master Magic, first you have to discard the thinking that it can only be used effectively from the back. Sure you can be a Mage that bombards enemies, however, being a Magic-Fighter is better overall due to their versatility."
"Magic-Fighter? How are they different from Mages?" asked Riveria.
"If Mages mostly just stay at the back to give covering fire or support, Magic-Fighters are those people who can use Magic to fight, regardless of their position on the battlefield. Well, that's the rough definition. The distinction between Mages and Magic-Fighters is blurry as reality could be a lot more diverse and complicated, you know~." answered Serafall as she conjured a spear made out of ice in an instant.
