Giant elephant. With 4 metallic tusks that's larger than an average human, wearing a fiery red hot armour. Ears capable of covering its whole body, and a tail that looks like a propeller. It's already massive size made larger thanks to the chant made by the head of the devil, causing the entire underground dungeon to collapse.

 Speaking of that devil, he firmly attaches his head and spinal cord between the two eyes of the elephant, most likely to control the elephant. Most likely, this elephant is a powerful beast, capable of going against the devil, but somehow found itself under the chant of this devil. If that's the case, this battle should he tad easier

Carrying Charlotte and jumping upwards, trying to escape the fall, the elephant shot few air shot aim toward us with its long trunk. It's fast, but thankfully, I am agile enough to dodge all the incoming attacks

(It stuck in the underground dungeon... Good) [Yuna]

"Yuna, what happened!?" [Rean]

"Rean, and all of you... Never mind, carry Charlotte and tell others to stay away from this area as soon as possible. Now! " [Yuna]

"What happened?" [Rean]

"NOW!" [Yuna]

Sensing the urgency behind my command, Rean quickly grab Charlotte hand, and together with his teammates, they sprint toward safety. Few onlookers and newbies adventures, sensing trouble brewing, quickly do the same.

(Better enhances myself with a few more spells first before...) [Yuna]

Just as I am about to start my chant, the elephant, flew in the air. Using its massive ears that's been coated with wind magic, as well as its tail rotating at high enough speed, it escapes the dungeon. It looks comedic, but given how powerful this beast of an elephant is, I can't help but feel even more tense

(The little blue hair girl... There. And what's this? I see, so just beside her is also another...) [Devil]

The devil glares in Charlotte's direction, and the elephant start firing another air shot, aiming directly at them. This air shot, it's stronger and larger than before, with an area of vacuum, capable of sucking in anything nears it. I see, this way, it will make sure the target getting sucked into the spell, reducing any chances of escaping and thus causing the target to take the blast 

"Tchh! Ice wall! " [Yuna]

The air magic collide with the ice wall. It's powerful enough to shatter basic ice wall of mine, a feat that's capable by at least B rank monster and above. The shattering ice wall scattered around, and since it's made out of my own magic, I simply control the shard, targeting the head of the devil as well as the elephant's eyes, but the elephant simply blew it away by exhaling a large amount of air from its trunk 

"You're in my way!" [Devil]

"But if course, that's my siblings you're aiming for. As long as I am still standing strong here, you won't even touch a single strand of their hair " [Yuna]

"Then you should die, for the glory of our God" [Devil]

Good, looks like the devil will not target them, instead, the devil temporarily shifts his target from Charlotte to me. 

With his shout, our battle begin.
