Adrien
It had been two months since Adrien's discovery. In this timeframe he had been practicing and learning more about his new powers. Noroo, despite wary of his master's intentions, was faithful and comforting to the boy. Adrien gradually became accustomed to his powers and decided that this night, he would leave his mark.
Senior Master Sergeant Coen Rios
It was the memorial service. He just kept replaying their deaths over and over again in his mind. It was his fault that they all had died and know he was all alone in this world. As he stood there, face devoid of emotion, he heard a voice. "I've gone crazy," he thought until he heard the voice again and this time it was clearer.
"I feel your pain, I can help you."
"Oh really, yeah right. What can you do, bring them back?" snapped Coen. He didn't need anyone messing with his emotions, after all there was nothing that could be done, right?
"Sadly no, I can not, however I can give you the power you need to get your revenge one the ones responsible for your friends' untimely deaths."
Reluctantly, he asked, "Who exactly are and what's the catch?"
"I am Espera, and all I ask is one small favor."
Marinette
It's not everyday that a supervillain goes marching through the streets heading straight for the French Parliament Building. Nor that you find yourself task with stopping said villain. Yet, that is the predicament Marinette found herself in, under her alternate identity Ladybug of course, and despite assurances from her new friend Tikki, it didn't look like this would be easy. It felt like only a few moments ago that deh had been gifted a box by an anonymous person. She had but mere days to get used to the whole "heroine" gig and now here she was, facing her first adversary.
"I will have those pencil pushers heads for sending my team to their graves!" exclaimed the Akuma, while violent swinging a spear with the French Flag on it.
Ladybug recalled what Tikki had said about needing to break the akumatized object to purify the akuma. She decided that it was most likely in the flag pole that was currently being used as a weapon. One particular thing caught her attention though, wasn't she supposed to have a partner? As they akuma continued his rampage, she decided to push the thought aside and deal with the task at hand.
Landing in front of the akuma she heard him bellow, "Get out of my way before I squah you!" Suddenly an eerie outline of a butterfly appeared on his face and he appeared to be listening to someone.
"Yes sir, " said the Akuma, "I am Brigadier and will be needing those earrings immediately."
With that he charged Ladybug and swung at her with fill flag. Narrowly evading the attack, dhe realized that she may not be so lucky next time. "Lucky Charm!" she shouted, hoping for something helpful. Landing in her hands was a pair of pruning scissors. Despite being somewhat disappointed she choose to try to stay positive. Ladybug was flung down the road by Brigadier, resulting in her dropping the scissors.
"You were honestly going to try and defeat me with gardening tools?" Brigadier couldn't help but laugh, "Just give up little girl, my quarrel is not with you."
Reacting quickly Ladybug tied his arms to his upper body with her yo-yo and cut the flag in half with the pruning scissors. Out of the flag flew a black butterfly, she almost forgot, then she felt Tikki reminding her, to purify it. "Miraculous Ladybug!" she yelled, followed by the a swarm of butterflies fixing all the damage caused by Brigadier.
After making sure akuma victim was okay she zipped off to her home. Safely detransformed and in her room, she collapsed in her bed. "Great job Marinette!" Tikki said excitedly.
"Thanks Tikki, there's some cookies on my desk." replied Marinette.
Unknown to her, the whole battle had been watched by a figure standing on the roofs, "So this is the one who is keeping my family broken."
