Alexandria

'''First seen and named as Ri. Which comes from the RI in Alexandria.'''

The great reveal happened at Chapter 179 - "A Final Exposition". After Dyon exposed Jade and her father of their great plot that was causing turmoil in the Elvin Kingdom. It is revealed that Alexandria (Ri), is actually the princess of the Elvin Kingdom, and that her mother is not human as it was said, but in fact is a beast (literally).

Before awakening of her lineage
She wore tight leather pants and a kilted short skirt above it. Her crop top was actually made of a protective armor that held her thin sword strapped to her back. Although her face wasn’t that of an extraordinary beauty, her silver-blue eyes had a calm and serene depth to them that completely contrasted with her fiery personality. Her hair was long, gently swaying across her exposed venus dimples and illuminating a beautiful stream of light blues and silvers that gave her an otherworldly feel that her barely pointed ears couldn’t match.

Her footsteps were light. Not a sound could be heard.

After the awakening of her lineage
After Alexandria's awakening, which is a True Deity body constitution called "Elvin Queen's Reign", it is revealed that she is a Kitsune (like Ahri from League of Legends). Alexandria after her awakening has become more beautiful (I assume, I think there was a bit of description about her become prettier), has grown TEN silver-blue tails (legends only record nine), and "her hair has darkened, but it seemed like everything else had brightened to a whole new level in response". So overall Alexandria's new features held a Japanese air to them, still having the same sparkling pure silver-blue eyes, but her skin has become more flawless and smoother, so much that a touch could make your hand melt.

Bestial Form
Vol11.Ch61 A long, slender fox of over a hundred meters was revealed. Every one of her four limbs was brimming with strength and power, the fine filaments of her muscle fibers twitched with every slight movement. Her fur was a deep black that radiated out with a dark blue glow. Her pupils were absolutely gorgeous, to orbs of blue sapphires that twinkled like stars captivated those below. Still, her most odd feature were her two tails. One radiated a deep, dark black fog, while the other exuded a frosty blue aura.

New Human Form
Vol11.Ch62 her slightly pointed ears were gone, her adorable canines were even more pronounced than they had been in the past. Her hair was no longer a light silver-blue, but was rather a deep navy that shimmered beneath the sunlight. Along with it, her two pupils were like blue pearls, contrasting her dark hair with a gentle light.

Bonus
No need to thank me fellow netzians. But Alexandira (Ri), is Dyon first sexual experience. And the chapter depicting this is Chapter 188 - ": 3"            '''Dyon is so damn lucky!!! I'm jelly!!!'''
