In your quest to reach Elysium with Pyra and Mythra, you befriended and enlisted the services of many beings known as Blades, weaponized life forms linked to a Driver who create and summon them by resonating with a Core Crystal. Blades endow their Driver with powers and a weapon that tend to differ depending on the Blade... With their help, the upcoming challenges don't seem so challenging anymore! This Blade is... Are you sure she's a Blade? Well that's what she says she is, so... Your newest ally is KOS-MOS, which is apparently short for Kosmos Obey Strategical Multiple Operation System. She has a robotic, emotionless, and logistical approach to any situation. She also supposedly has access to a database that gives her the answer to whatever is asked or presented. She is the wielder of an Ether Cannon and the Element of Light, an absolute rarity among Blades, and has a number of other pieces of tech that give her an edge in combat such as the R-Blade to concentrate energy into a laser sword and slice enemies to ribbons, The H Effect R to unleash an influx of energy that attacks every enemy in the vicinity whilst restoring the health of the squad at the same time, The F-G-Shot to fire a wide array of scattered lasers, and the X-Buster to unleash an enormous laser from her chest... With KOS-MOS at your side, it's hard to imagine any hardship in the future actually being hard. This instance kicks off with you walking around in the Empire of Mor Ardain with KOS-MOS at your side

Master, we must not forget that Pyra and Vess require us to fetch ingredients for dinner tonight.
