Prisms (Creatures)

They’re Small, Genderless beings of solid light, who have a preferred dormant state (when they look like a shaped gem), a preferred active state (when they look more like a crystalline creature), and can shift into other forms made out of that solid light, such as the magical soldiers “armor” and weapons.

They can’t communicate well, they aren't native to our setting, and they are very particular about choosing their hosts, They cannot be forced to/WILL NOT partner up with anyone they don’t deem as worthy.

They also won’t take the form of anything they don’t personally want to take the form of, regardless of if their host asks it. They’re weird little things! They like what they like and that’s that!

And what they like comes down to the individual Prism. One could happily act like some sort of sentient multi-tool while another never transforms outside of its own dormant/active phases and transforming into armor and weapons for its host. Completely depends on it’s personality.

For this same reason, a magical girl has no control over what her outfit or weapon theme is! It’s based on the Prisms taste. You don’t like your scythe? Too bad! Your Prism does!

All known Prisms on earth are kept by a magical girl, or locked away inside the PRISM building. And the magical soldiers name their own Prisms! Which yes, is why Nenekos is named Mayonnaise, 'June'

The amount of power inside of a Prism can be determined by how many colors are on the Prism, even more so when it becomes the armor of a magical girl, the average amount of power/colors on a prism is one main bright color and one bright accent color.

Hisako Miyu is one of the weaker magical girls as depicted by her outfit being primarily black with pink accents

Neneko Aino by this logic is very obviously one of the strongest magical girls in the entire organization, The second strongest in fact, and even In some albeit very rare cases magical girls like Katsumi Katayami can gain more colors and therefore become powerful through (possibly) various ways
