Twin Souls: Reunited

WARNING!
This story is something I have always thought of writing and let me tell you, this will be severely cringe and with no editing whatsoever. I'm only writing this for my self-indulgence, updates will be sporadic and I hope to the stars that nobody will read this TT

Anyways, back to the story description.

For others, their way of living may be inconvenient and at most unrealistic. Regardless, they had to push through. They only had each other now, they won't be separated no matter what, even if one of them is dead and only serves as a ghost companion to the other. They will live no matter what even if the world never seems to want them alive.

ALT summary:
Althea Zalnoe, a spirit bound to her twin brother, Adonis Zalnoe. Who was also the main character of her favorite novel back on Earth, was now trying her best to survive in this unexpectedly crazy world. She never thought that these types of stories were real. But apparently, they are and now she has to deal with this crazy plot where monsters called 'Anomalies' wreak havoc every time they appear, an organization called 'Soteria' is constantly hunting monsters and...freeing them...? And a corrupt corporation called 'Lunar Stars Inc.' always seems to have a twisted fascination with her twin brother for reasons she would rather deny than acknowledge.

She just wanted to die in peace, what the fuck is this?
