She even has moves and costumes based on Trails characters to further expound the point!
Also, fun fact, both of them share the same JP seiyuu as Estelle Bright, the Trails franchise's first of many protagonists, while in English, their voice actress (also the same) would voice Altina.

It could be a nod to Falcom itself having two flagship titles, which reflects in their designs and personalities. Hyper-Falcom is older and more experienced, as Ys is the first of Falcom's franchises, while Ultra-Falcom is younger and starting out, as Trails is a later franchise.

The character I chose (Nepgear) is known for tinkering with tech stuff (hence Nano Gear), so this is what I'm going with.
Side note, I can see almost all the characters in her franchise (Hyperdimension Neptunia) using Keyblades.
