Show of might

With a shout, Erigor's magic formed around Inari and Natsu. Natsu was flustered, since his magic wasn't affecting the tornado. Inari, on the other hand, simply drew his sword.

"Natsu, come here and get down. What happens next might hurt!" Inari

Natsu quickly crouched down next to Inari, who told him to cover his ears. That done, Inari pointed his sword to the skies, invoking his magic. With a bang loud enough to cause pain, and a flash of light bright enough to blind, a purple lighting bolt struck his sword. Due to the nature of lightning, the air within the tornado rapidly expanded, dispersing the tornado in a huge dust explosion.

"Impossible! How could you so easily destroy my magic?" Erigor

"That's just the way my lightning works. Now, are you going to surrender or must we hurt you!" Inari

Erigor was livid. Suddenly, he took out an evil looking flute with a skull on it. As he took it out, it started to glow slightly purple. Seeing this, Erigor started laughing maniacally.

"Ha, I was going to use this to kill all the guild masters at their little conference, but you deserve to die!!! BEHOLD, LULLABY!!!" Erigor

Both Inari and Natsu were confused. They had never heard of this 'Lullaby' before, and had no idea how to react. As Erigor raised the flute to his lips, though, both of them got an intense feeling of impending doom. Without delay, Inari shot a bolt of lightning at Erigor, while Natsu used FIRE DRAGONS ROAR. Immediately, Erigor was shot down. However, the flute started pulsing with an intense magical aura.

As this was happening, on the floor of the valley in which they were fightng, a magic mobile was driving. In it were Erza, Gray and Lucy. They looked up to see Erigor falling down from the train tracks up high. Stopping, they were just about to go and check on him, when a pulse of eerie magic reacched them. Suddenly, the flute in Erigors hand started growing, transforming into a giant of 50 meters.

"Erza, Gray, Lucy, you guys are alright. Looks like we have a bit of a problem here. Erigor over there said that this is Lullaby. A demon flute apparently. What do we do?" Inari

"LULLABY!?!?! The flute the black wizard Zeref made that can kill with it's sound?" Lucy

"This is bad. Judging by the fact that he was going to Clover town where the Guild Masters are meeting..." Gray

"He was planning on killing them. We stopped him, but now we have a monster to fight." Natsu

At that moment, the Lullaby demon finished forming. It had a wood-like aesthetic and 3 eyes on it's head. It looked around for a moment, before looking down at the fairy tail wizards.

"HA HA HA HA!!! TINY ANTS, BOW BEFORE ME AND I MIGHT SPARE YOU!!! OTHERWISE, DIE!!!!!" Lullaby

The group got ready for combat. Erza requiped her Tenrin no Yoroi, Natsu set his hands ablaze, Gray cupped his left fist in his right palm, exuding cold air, Lucy called forth Taurus from the Celestial world, and Inari drew his sword, lightning crackling in the air with flames blazing around him.

"We can't afford to hold back. I will blast him at full power, then you guys attack." Inari

Everyone nodded in the affirmative. Inari focused, calling upon his magic. Lullaby broke out of it's reverie, sensing immense magic power leaking from Inari.

"YOU ANT, YOU DARE ATTACK ME!!!! COME, MEET YOUR DEATHS!!!!!!!" Lullaby

"EVERYONE, ATTACK NOW!!! Moeru sandāsōdo (Burning Thunder Sword)" Inari

Inari slashed, emitting a huge blast of red fire, crackling with purple lightning. It impacted Lullaby, pushing him back into the valley wall. Before the attack ended, Natsu used Fire Dragon's Roar, Gray used Ice Make: Lance and Erza used Blumenblatt. Lucy just watched, mouth agape in wonder. As all the attacks hit Lullaby, it let out a cry of pain and fury. An immense explosion occurred, causing the valley wall behind it to crumble.

"YOU INSECTS!!! HOW DARE YOU!!!! I GAVE YOU A CHANCE BUT NOW YOU CAN ALL JUST DIE!!!!!" Lullaby

Lullaby breathed in as if to release a breath attack, when suddenly off tone squeaking could be heard from it. Suddenly, a plethora of holes burst open on it's body, through which air escaped.

"Damn, didn't expect you to survive that. Well, here's my final attack; Sekainoowari: jigoku no yobidashi-moto (World's End: Hell Caller)!!!" Inari

Underneath Lullaby, a circle of pure red flames appeared. Above it, a sphere of purple ligtning apppeared. Both were larger in diameter than Lullaby, and radiated power.

"NOOOO!!!! LET ME OOOOOOOUUUUTTTT!!!!!!!" Lullaby

"Sorry, no can do! Kanraku (Fall)!!!" Inari

The lightning ball fell, pushing Lullaby to it's knees. Gradually, it started sinking into the circle of flames. As it struggled, Inari became aware of his guild-mates looking at him in curiosity.

"It's a seal. Traps whatever you want in a pocket dimension, similar to requip magic. However, this uses my magic to start the seal, then starts siphoning the targets magic to maintain it. Should last indefinitely that way. The only thing is, I can't interact with the seal once it has formed." Inari

"So you're saying we should keep a look out at this location?" Makarov

Everyone turned around to see their master, along with a few others, just a few steps away.

"Well, this is interesting to say the least." Erza
