Why are there monsters in the world?


Who is the Great Dark Overlord?
It is a being from another world, made with the sole intent of absorbing all living beings into itself. By using monsters to wreak havoc, the Great Dark Overlord forced the contractor being known as Platina into creating a magical girl from the human Ferrous, who would then combat these monsters, and cause both her mana and that of the monsters she defeated to be returned to the Great Dark Overlord.
After building sufficient strength, she managed to take over the body of a worker at Tomorrow's Path Laboratory, a colleague of Ferrous' mother in particular, marking her first true personal breach into the human world, and taking on the name "Sheol". (Due to the host body being a female, the Great Dark Overlord is also referred to as a female.)
Though Ferrous had managed to best her in battle, due to Sheol opening a tear in space-time, it is unknown as to the Great Dark Overlord's current fate, though it is more than likely that they are alive in some way, shape, or form.

Instantaneous Transformation
Generally, a magical girl must catalyze sufficient mana within her own body to cause the reaction necessary to transform, which necessitates a non-minor amount of time. Mana gathered in the body this way is gradually released into the air, which is negligible when compared to the amount at which a magical girl's body produces mana, but after reverting, this mana quickly dissipates into the surrounding air.
However, by suppressing this mana as a magical girl, one can enter a pseudo-magical state, where mana is retained within the body, but no changes in appearance or power are detectable.
However, due to maintenance of this state also requiring a suppression of natural mana production, Ferrous has also opted to consume more food to compensate for the loss in mana.

The Lawbreaker II
The original Lawbreaker was an artificial metallic hand that appeared in place of Ferrous' right hand while transformed, capable of firing rounds from the fingers.
However, after the Lawbreaker was cut off her arm during the fight with Metallic-A, Ferrous was unable to properly operate the weapon. This led to Platina imbuing themselves into the Lawbreaker, allowing it to take its current form, the Lawbreaker II.
It takes on the appearance of a five-shot revolver capable of holding .45 rounds, though its primary form of ammunition appears to be "mana bullets", ammunition made from her own mana that can also be charged to detonate with force. Ferrous is also capable of using mundane ammunition, even ammunition that should not be able to fit into the Lawbreaker II, like missiles.

Heavy Weapons System (HWS for short, also known as "Multi-ArmamenT Armor for Dealing ORdinance")
Made from materials scavenged from Ferrous's house and Tomorrow's Path Laboratory and assembled through liberal use of Ferrous's magic, it is a near-encompassing bodysuit made of various metal plating. Its primary design intent was to promote longevity in combat, especially against multiple enemies, as Ferrous would face in her confrontation against the Great Dark Overlord.
Missile launchers are located on the waist and forearms, to add to her firepower.
To compensate for the additional mass, thrusters have been installed in various parts of the body, though the thruster output is severely limited by the amount of strain induced on Ferrous's body when used.
Though it would see use during Ferrous's fight against the various monsters of the Great Dark Overlord, the HWS would not be seen again afterwards, as Ferrous would discard it in order to use her usual agility in her final confrontation.

* Ferrous is her actual name. Her parents had a terrible sense of naming.
