Fairy Tail: The Fourth Master

Mirajane stared at Kagura, she unfolded her wings and levitated a fee above the ground before she flew towards Kagura as she threw a punch.

Kagura reacted quickly and used her 'sealed' sword to block the punch, causing a powerful shockwave which destroyed the ground below them.

Kagura narrowed her eyes, she wasn't expecting Mirajane to have a powerful physical strength almost on-par with her.

She used a bit of strength and pushed Mira back, then she pulled back her arms and twisted her waist a bit before throwing a powerful punch.

Mira managed to block her punch by crossing her arms, but she was still sent flying and her arms turning numb.

Mira balanced herself in air as she gathered an energy from the surrounding area between her hands, which subsequently takes the form of a large, black globe.

She glared at Kagura before firing the globe in her hands towards her, as it turns into a large black-purple beam.

"Soul Extinction!"

Kagura reacted quickly, she unsealed her sword and slashed it forward, as a large wave of energy pierced through the beam and continue to go towards Mira, who dodges to the side.

Mira looked behind her and was shocked by the damage done with Kagura's simple swing, several titanic-trees were destroyed.

"Don't take your eyes off me." Mira's eyes widened and quickly tried to retreat, however Kagura already send a powerful kick to her stomach, while using her magic to further increase the force behind it.

"..Guh-!?.." Mira's eyes shrank as air escapes her lungs, Kagura once again attack, she send a powerful butterfly kick reinforced by her gravity magic, hitting Mira on the cheeks, sending her flying dozens of meters away.

Kagura remained on guard, she doubt that the 'little' attack she did would caused Mira to go down easily.

As expected, Mira appeared in front of her with a kick, which Kagura easily avoided as she leaped backwards, gaining some distance from Mira.

Kagura glanced at Mirajane as she raised an eyebrow, "....New form?"

Mira let out a smirk, "Satan Soul: Sitri." she was now in a geometric printed body suit with a blue and white dress coat adorned by an over-sized black collar supported by two belts which corsets her waist and a black cape.

She has horns on the side of her head and she also grows a lot more hair. She also grows a pair of claws and royal blue markings appear on her legs. She is surrounded by flames which her feet seem to be merged to.

"....." Kagura remained silent as she observed Mira, she doesn't have any idea of her abilities in this new form of hers. In a fight, just a slight mistake can cause you to lose.

Suddenly, Mira formed a large dark purple as it shoots countless of small lasers.

Kagura dodges with a little movement, she ran in circles around Mira. Then, she instantly appeared behind Mira while using the back of her sword to strike.

However, Mira swiftly twisted her body and send a kick, Kagura jumped as the kick missed her, then she grabbed Mira in the face, increased the gravity before slamming her head on the ground.

"Grgh-!?" Mira endured the pain and grab hold of Kagura's hand on her face, she used her other hand and formed a dark purple orb and aimed it Kagura's stomach.

Kagura's eyes widened but quickly let go of her sword and grabbed Mira's hand, and aimed it at the side, as the orb shoot from her palm, before turning into a beam.

'BOOOM!' A large explosion occurred, destroying a couple of trees.

Kagura fiercely glared at Mira before sending a punched on her stomach, the punch was so powerful that the ground cracks from the impact.

Mira let go of her hand, as she went out of her transformation and she was barely conscious.

Kagura stood up and walked away to picked up her sword and sheathed it, before taking a glance at Mirajane. Her attack wasn't that fatal, she made sure of it, at most she'll be unconscious for a few hours.

'I still have healing potion in me, I better heal her.' She began to approach Mira, however her eyes widened when she saw her slowly standing up.

"Haa~...Haa~...Not..yet....I'm still...not..done yet....Haa~"

Kagura showed a trace of worry in her eyes, no matter what, she's still a guild mate, she was worried of whag will happen to her if she keeps pushing her body beyond her limits.

Thinking of that, she was reminded of Natsu, who, despite his body already went beyond its limit, he still pushed himself to stand.

'...you two...are somewhat similar...'

She slowly approached Mira, who could barely even stand with all the injuries she sustained. Then, using the end of her sheath, she poked Mira's forehead as she fell down.

Kagura caught her before she could fall in the ground and lay her down slowly. She stared at her eyes, which are showing bitterness, sadness and other emotions.

"....tch! Don't expect to help you pursue him..."

Hearing those words, Mira's eyes widened in shock, before she let out a sweet smile and fell unconscious.

Kagura took out a bottle that has a pink liquid inside, 'This potion isn't as effective as the one given to the saints, but it will do.'

She opened Mira's mouth, and with a swift movement, shoved the bottle of potion to her mouth.

'Cough!..Cough!..' Mira coughed the potion outside her mouth, causing Kagura to narrow her eyes.

"This bottle cost me no less than two million jewels, but you coughed it up just like that?"

Then, she once again took out a bottle of healing potion, but this time she did not made Mira to drink it, but instead put the content to her own mouth ans transferred it to Mira through mouth-to-mouth.

After she made sure that Mira drank all of it, she separated her mouth and wiped her lips, as she carried Mira in her arms.

She decided to return back to Natsu's house, however she saw Ultear leaning on a tree with smile on her face.

She clicked her tongue and ignored her as she continue to walk while carrying Mira.

"Ara~? What's this? You actually gave someone, other than Ariel, a permission to pursue Natsu? And you didn't even ask our opinion."

Kagura ignored her and continue to walk away, Ultear laughed and followed after her.
