On one fateful day, when everyone went on with their mundane lives, the Earth was found in the Dark Forest known as the universe, resulting in unknown extraterrestrial beings preying on the weak — the humanity. Grey, an intern, was then killed due to an alien invasion, only to find himself reincarnated in the mysterious world known as Magica. But wait... "I've become an alien?!" Integrated with a mysterious entity known as the Extraterrestrial System, follow Grey's journey as he begins to seek the mysteries of the world while gradually, slowly, but surely building his Alien Empire despite being surrounded by powerful existences such as Heroes, Demon Lords, and other magically powerful beings.
The sudden reinforcements that appeared out of nowhere were enough for Amara to question her existence. As someone with a renowned background, even though she was discreetly treated as a disposable yet valuable alchemist of the household, she still had ears for high-level or classified information regarding her family's internal affairs, which included but was not limited to useful information about talented individuals that could be scouted by the family.
With this being said, she had never heard of anyone who could utilize an unknown spell that summoned tens of doors exuding purple mist. If this woman was known, it was clear and certain that the spell caster's identity would spread not only throughout the Holy Empire but of the World of Magica.
'Who is she…?' Amara thought, on her sides were a few strange-looking demi-humans that resembled a crab standing on its own two feet.
