Space. It was a vast frontier for the organism. So many life forms to absorb, so little time. The new world it had landed on was different. The area seemed warped in a different plane of space. It didn't matter to it though. In the end, any life form would be absorbed into the embrace that is Megahex.

Except for this one, it seemed. For all its worth, Megahex's attempt to absorb the brain-like monster wasn't working. He tried using multiple copies to try and grab it, only for them to be blasted away. Megahex took a while to analyse the thought process of this new opponent.

The memories of this monster were… interesting to Megahex. They weren't that of a blobby brain, but rather of a young girl. A young girl and what seemed to be sad memories of her friends. Friends who fell over dead as monsters like the brain emerged. And standing in the middle of these memories were feelings of rage towards a cat with long bunny-line ears. All he knows is one thing:

"I wish the Incubators would just disappear from this world forever!"

A demand. Whatever this girl said, it wound up causing these cats to disappear from her world. He then saw her world freeze over and eventually disappear among the stars. This is something that, as a cosmic being, he is all too familiar with: heat death. And that's when the girl despaired and became the brain monster that he saw before him.

"I assure you, you will never worry about that if you become one with Megahex. I will promise to bring an end to the heat death." Megahex told the monster. He took a while to translate the wails and screeches.

"How can you ensure heat death's demise? Not even the Incubators are able to fully stop it." It said.

"… Simple. The heat death is inevitable. Time is our enemy, not the heat death. Join with me, and we will destroy the heat death by ending time itself!" Megahex said. The Oblivion Witch stayed silent for a few moments before finally saying:

"Very well. We shall succeed where the Incubators failed." Itzli said.

"Rise and shine!" Kouta awoke to the sound of a cheery girl and the curtains being ripped open.

"G-Gah!" Kouta rushed up from the bed and looked over to see a pink-haired girl he had never seen before.

"W-who are you?" Kouta asked her.

"Huh? Don't you recognize me? I'm your little sister, Madoka!" Madoka said. For a moment, Kouta was about to question her. However, Kouta had a headache as he began to remember the day he found out his parents were killed in a car crash. He recalled a family portrait of himself and Akira. Soon, four figures began to fade into the picture. A three-year old with white hair, a businesswoman, a bespectacled man, and lastly, the girl herself. Kouta shook his head.

"I… I remember now. Sorry, must have had a lapse in memory, eheh…" Kouta patted Madoka on the head as she smiled.

Kaito awoke, his heart racing as he checked his face. Thankfully, his face being violently grabbed by his father was just a nightmare. Kaito allowed at least one tear to come out before he quickly wiped it away.

"So, you got a bad dream too, huh?" Kaito turned to see a tall girl with long red hair tied up in a ponytail. He just looked at her for a moment before his mind flashed. He never recalled the time his parents attended what amounted to a cult until today. All he remembered about it though was that the red haired girl was someone he met when his parents committed suicide and left him in the orphanage

"Hmph. So what if I did, Kyouko?" Kaito asked her. Kyouko simply grinned.

"Well, I can't blame ya. You're just lucky your parents didn't have the courtesy to burn down the house." Kyouko's smile faded as she sighed. "So, are we gonna do some dancin' or what? Those punks at Raid Wild need a good beatin'." Kyouko said. Kaito nodded.

"Yeah. Time to herd the sheep." Kaito said.

"Get away from me." Mitsuzane said to the blue-haired girl following him.

"Oh come on! We're basically siblings with how close we are! Just walk me to the gate at the very least!" Sayaka told him. Mitsuzane had a hard time remembering her, though his memories of maintaining a double life have been muddled with memories of her involvement in both those lives.

"If I get caught with you, my brother will find out about my involvement with the Beat Riders." Mitsuzane calmly said.

"Geez! You're no fun, Micchy!" Sayaka skipped along to keep up with Mitsuzane. "Besides, you're on the Beat Riders Hotline! How can anyone not notice you?" Sayaka said.

"Parting the hair slightly helps." Mitsuzane muttered. As Sayaka followed Mitsuzane, all he could think of was how this didn't seem right.

This didn't seem right, Takatora thought. No one would have been able to have snuck into Yggdrasil Tower undetected. He marched forward to where this supposed rogue went: his office. Why his office though? All he keeps there that's important was his Sengoku Driver, and only he can wear it. He slapped on the Genesis Driver, just to be on the safe side. His fingers in his pocket, just feeling the small detailing of the Melon Energy Lockseed. Just then, he stopped.

Ryoma wasn't done working on either the Genesis Driver or the Energy Lockseeds. He pulled it out and looked at it.

"So… You noticed." A female's voice entered his mind as the hallway he was in suddenly blackened. When the lights came back on, he was in his office where he could see a woman with long black hair, dressed in a black gown. She turned around and looked to Takatora. "You know that there is something amiss with your world's timeline." She said.

"… Who are you?" Takatora held the Melon Energy Lockseed, ready to press the button. She chuckled.

"Well, I guess you can just call me a demon. A demon who has just as much questions as you do." She said.

[Author's Note: And so, we begin a new fanfic. Yet another Kamen Rider Gaim/Madoka Magica fanfic. This is a fanfic idea from Bighead98, where the idea is just as the summary says. I took a few liberties with the premise he presented. I decided a brief prologue to express a bit of the premise would work.]
