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 official duel between Hero Kindred and what most people referred to as nobody began.
Donning his usual laboratory coat and black pants, which were made from his very alien flesh, Grey formed a defensive stance. In his grasp was not the [Anon Spell Blade] but rather something else.
It was an obsidian-colored katana, with a blade akin to the night sky, cold but beautiful. It's streaked with resplendent stars depicting the constellations in the vast sky, which seemed to be storing an unusual kind of energy.
Such a serene weapon was a first sight, even for Yeri.
With utmost curiosity, she inwardly muttered,
'What is it, Honey Mallows?'
Yet, Honey Mallows provided a vague answer.
[One of the swords owned by the Demon Queen of Heavenly Swords].
Not only her but the spectators close to holiness, Solana von Lumen, and Yeri's classmate, Naya von Lumen, seemed to feel that something was amiss with this weapon.
