Note about Mariko's gadgets and weapons

Mariko only comes to use fire arms or another weapons when the mission provides it to her. But as a mercenary, disliking it or not, the time will come when her bare hands (or claws) aren't enough to get the things done. For this matter, Mariko may carry a pistol with her.
The pistol itself has a high-tech look and uses particle shots instead of bullets as ammo. The intensity can also be regulated between a stun shot and a kill shot. By default, Mariko locks it on Stun levels to prevent the misuse of this weapon in case of be stolen. The particle shot can also be concentrated to make a laser beam to cut objects, similarly how the phaser works in StarTrek, but it requires unlock the higher intensities. Similarly to where you shoot a person, firing in stun intensity on the head or chest, may knock out the victim or simulate the pain of a burning zap if shot somewhere else, depending of the intensity. The effect of stun particles are temporary and won't cause any long-term harm (if their heart is healthy).
Visually, the difference between the stun and kill intensities are indistinguishable. One who is not familiarized with this weapon, can't tell if it's on a deadly high intensity or a harmless low one which only gives a small itch. For all cases, Mariko uses it as a tool rather than a weapon.
