[A/N: This is an unofficial sequel to alexmagnet's Mahou Shoujo Spike-chan. I'd recommend reading that first. Enjoy!]
Spike never really wanted to be a magical mare, but he has since gotten over it after making his contract. Now, he rather enjoys being the hero and keeping Ponykind safe from harm. Celestia did entrust him with the mission of hunting down monsters after all, and he had no desire to fail his princess.
Well, at least, not before being confronted by Fluttershy, telling him he was stupid for making the magical mare contract.
Spike begins to wonder if all the feats he performs for society are worth anything.
What will happen when he succumbs to his grief? Did he not know that that is the fate of all Magical Mares?

Additional Author's Note: With permission from alexmagnet, I've been given the opportunity to write this unofficial sequel. However, he used a mix of common magical girl anime tropes, whereas I'm going to try funneling all of that into a crossover based on Mahou Shoujo Madoka Magica. With that said, this is going to be considerably darker than the original. I hope you enjoy it. Also, the image was taken from this video.
