Kisei Manor... Three floors of unknown, three floors of... Something writhing in the halls, and you are the one being sent to investigate what was supposed to be two disappearances.

You're alone, with only your weapons, against whatever calls this place home.

And unfortunately for you... The manor is occupied.

Manako, The Eximus: She is a living weapons factory and she doesn't need to worry about not having a gun when she can literally mutate her arm into one. She has the firearm knowledge to know what works and what doesn't, and she will use it with extreme prejudice on anything that's not like her.

Senko, The Ancient: While Manako is the firearms specialist out of the two, Senko is the one who has mastered the elements and has turned her body into something like a conduit. Her arm will change depending on what element she's using, but no matter what she chooses, it's going to hurt a lot.

Only one intro for this one, an equal chance to encounter one or both of them. Good luck, you're going to need it for whatever you do in the manor.
