Rarity and Trixie hovered above and followed a path. Rarity was attacked by many of those magical sawblades or whatever they were. But some of these ones could fire a lone energy ball. Occasionally a youkai or two wearing a pink dress would show up and attack. As she went on, more youkai showed up at a time. She unleashed a frequent barrage of magical spikes upon all of them. The more there were, the harder it became to dodge all of their attacks.Luckily, most of them went down quickly.
Then an earthpony youkai appeared. How it was able to hover, she had no idea. It had a pink skirt you would expect a filly to wear. It cast spirals of green energy balls from it's\her staff. It then tried to limit her movement by making an unmoving arrow pattern out of light blue energy balls. It then tried it's luck with purple and green arrow projectiles in spiral patterns.
"Wait, wwaaaaaaaiiittt!" The youkai screamed.
" Huh?" Rarity said, confused.
"Where are you going at this time of night?"
" It's Rarity's youkai extermination month. I'll go wherever youkai live!"
"Wait, what? Are you trying to pick a fight with me? " the youkai half-laughed.
" 'Rarity's youkai extermination' hilarious."Trixie remarked sarcastically.
"Oh, don't you know how amazing I am at that? I exterminate youkai and ponies with final spark all the time!"
"You. Pony. Don't you have any idea who I am?" The youkai half-growled.
"Huh?"
"All ponies fear me in the darkness! If I wanted to, I could call so many youkai here they would eradicate every pony in the land!"
"...Heh. That's enough chirping, you windbag." Trixie interrupted.
Rarity laughed a little bit. "Looks like you still don't get who I am. "
"Pony?"
"Pony." The youkai said.
"Pony all the way." Trixie giggled a bit as she said that.
"Uh...right..." Rarity stuttered out.
"See. Starting tonight, you two will never again be able to see in the dark! I am Mystia!"
She started firing spiral patterns of green energy balls. Rarity struck back with full force. Most of her attacks were stronger versions of the ones before. They were still powerful spell cards nonetheless. Then she tried to use a barrage of one single pillar of red energy balls, purple arrow projectiles, and slow-moving dark blue energy balls. Rarity kept her assault of magical spikes going.
The next spell card Mystia used looked complex, but was the easiest to avoid. The trouble was that it seemed that she was losing her sight. Oddly enough, Trixie took control of the fight. She seemed to be having the same problem as Rarity, but was still able to barely dodge the attacks thrown at her and fight back.
Trixie dealed the final blow, and Mystia plummeted face-first into the ground.
"Much better. Got rid of all that darkness!" Rarity said.
"Damnit, we've gotta get moving! We don't have time to waste on small fry!" Trixie half-yelled agitatedly.
"Where are we going anyway? I'm sure there are no enemies that way."
"I can sense powerful energy coming from that direction..."
"Only ponies live in that direction. Totally innocent, just like myself."
