My little Soul Eater

Assasin's rule number one; Silence. Erase your breath and melt into the shadows.

  A rainbow maned pegasus carefully crept over the rafters of an old building, eyes fixed on the gathering of a hundred masked ponies feasting upon innocent souls. The blade of the katana between her teeth throbbed with a faint pulse. "Be careful Dashie, there are many Keishan egg souls down there." A warbled voice echoed from the sword.

  "Yeah yeah I got it Shy!" The cerulean mare replied. She shifted to just above the leader of the table, a petty crime leader named Sombra.

Assasin's rule two: Trans positional thinking Observe your target. Notice their weaknesses.

  "Now Family, we have found the location of a Witch. With all one hundred of you useless Crystal unicorns and those guns, we can defeat her. We will become Keishans if we do! Lets finish eating, and then we will go. Finally... We will be rewarded!"

  The pegasus smiled. Her katana glowed faintly, the shiny blade reflecting a bubblegum pink maned pegasus. "Remember rule three." The butter yellow filly smiled. "It is the most important rule of the assasin."

Assasin's rule three; Surprise. Sneak up on your enemy and emerge from the shadows. Attack before they can respond.

  "YAHOOO!" Rainbow lept down, her cry peircing the air. she aimed Fluttershy downwards, aiming for Sombra. With a resounding thud, the katana found its mark. It was now lodged deep inside the table, an inch from Sombra's startled face. " I AM THE MIGHTY RAINBOW DASH AND I AM HERE TO KILL YOU AND HARVEST YOUR SOULS!" She cried. Somewhere on another plane, a butter coated filly facehoofed.

  " It isn't an assasination if you tell them you are going to kill them! " She hissed. The rainbow tattooed mare frowned. The unicorn family had fled while she had listened to Fluttershy.

  "LOOK WHAT YOU DID NOW I HAVE TO FIND THEM!" She yelled loudly. Fluttershy flinched and returned to pony form.

  "I am sorry Dash. It will not happen again. We should go report to lord Celestia. She will be disappointed." Fluttershy said softly.

  "Let's go then! Can't let down Celestia! She is probably missing my lovely face. After all, who wouldn't want to see such a big star?" Dash exclaimed. Flutter simply sighed and walked towards the door.

        *********

  Celestia gazed angrily at the two fillies cowering before her. "Rainbow Dash, another failure? You have yet to collect a single keishan egg! At this rate, Fluttershy will never become a Celestial Blade! A punishment is necessary." As Rainbow Dash trembled before the raging goddess of the sun, Fluttershy stepped forwards.

  "No. It was my fault, not Dashie's. If you punish anyone, it had better be me." Fluttershy stood trembling defiantly before the pissed off sun goddess.

That's the bravest Shy has ever been. Maybe... "Whoever said you would be expelled? Although it does seem a fitting punishment..." Celestia said, carefully watching RD.

  "NO! Don't. I love Shy! She is the only one that can keep up with such a big star... I love her. She is the world to me. What you do to her, do to me. Times ten." Dash moved to stand beside Shy.

  "I was kidding. I plan to have you guys clean the library as a punishment, learn to take a joke! But it is good to know that you have found a soulmate Dash... Everyone has been placing bets on who you'd fall in love with. You would be surprised, most have been betting on that miss Cherrilee, you know, the teacher?" Rainbow gagged.

  ' A TEACHER?! Teachers are so stuffy, they would never be able to keep up with me!" Rainbow Dash started laughing and Celestia joined in.

  A few days later, Rainbow Dash and Fluttershy stood once again within the Celestial room.

  "As I am sure you know, you have accepted the mission involving the crime leader, Sombra. After his escape the first five times, we have finally tracked him down. He is, along with the unicorns he has corrupted that are part of his Mob 'family', going after a witch by the name of Applebloom. Now, this is the perfect chance for you. If you can somehow defeat the witch Applebloom and all of the 'family', you can almost instantly have a way for Miss Shy to become a celestial blade. As a shadow weapon and her Meister,  you two hold great power. Her flexible ability to change modes offers a variety of attacks, meaning more ways to easily defeat your opponents. Now, before the two of you set off, there are two things you should know about the witch Applebloom. One, she has a powerful guardian that many have lost their lives to. You must defeat him to get to her and claim her soul. And two-" Celestia watched as a rainbow colored blur sped out of the celestial room.

  A dark red earth pony stood in front of the nine hundred and ninety nine crystal unicorns and Sombra, looking at them fiercely with a case of swords by his side. "Eeyup. Sombra is it? I presume you've come to take the soul of the witch Applebloom, eeynope? Too bad, because as her guardian, I won't allow it." The red stallion lurched the case of swords into the air, swords and police tape sent flying everywhere. As the unicorns used their magic to fire their guns, the swords pierced their bodies. The screams could be heard a mile away by everyone in the nearby village.

  "Come ON Shy, you're taking too long. What if another student came and stole my thunder while I waited for you to catch up?!"
