"He is only akin to the gods himself, but your meaning is taken."

She inclines her head. "Unfortunately, I cannot hold the sun long enough for you to grow familiar with your powers. But your instincts should guide you."

"They always have. When you are ready."

"Shine brightly."

And the light flares again -

And Ellisaria is back, facing Kaguya, the unraveling threads of reality filled with sunlight for a brief moment before they snap back together.

The sun swells within her, and she roars in renewed defiance. With the power of the forge, she creates the blocks that will ignite the air, and hurls them at Kaguya. Her own native magic catches the fire, harnessing it, intensifying its power. But it is no longer the purple-black shadowflame she wielded before, the consumer of life and warmth. This fire burns with golden purity, the cleansing essence of perfection that scorches all it touches.

Kaguya surrounds herself with a sphere of negation -

And the flames lick around the edges, not touching her but instead turning the sphere into an oven.

She doesn't want to leave them here, in her nursery, but the world is large...

She moves herself and herself alone, slipping between dimensions.

And Sasuke, whose eyes now contain the Rinnegan, who had a divine vision of his own -

Opens a gate to follow her.

Ellisaria leads the charge through, flames blazing a path ahead of her. She would not before have been able to control pure flame in this fashion, but to this fire she has a connection. It is a mirror of the one she holds inside , and she can feed it continuously, with little effort.

Kaguya seems to be taking them seriously now.

Her bones lash at the group, massive spears of white lancing for everyone's center-mass - 

They're not ignoring the sun-flames like they had been the shadow-flame.

Good. Perhaps there's something to be said for holy magic.

Ellisaria deploys the sunfire in greater quantities, seeing as it's effective. She directs it to both intercept attacks and attack Kaguya, flying evasively.

The spears crumple and turn to ash before they reach anyone. Kaguya scowls, and gravity starts misbehaving, multiple points of both attractive and repulsive forces opening.

This trick is getting old, but her response has become well-practiced at this point.

The spheres start growing, and Kaguya uses them to weave spheres of negation among, targeting her opponents' attacks and their bodies, especially the Edo Tensei.

Hm. What if...

She intercepts a sphere of negation with a glob of sunfire.

They destroy each other.

As expected. Shadow and holy are linked opposites. In balance, they cancel. Ellisaria can't control her fire as neatly as Kaguya can control the spheres, but she can create it more easily, it seems.

A blizzard begins, the ice whipping towards Ellisaria, temperatures plummeting rapidly.

Ellisaria sets her fire in opposition, warming the area. The cold is not as troublesome as it was. Her new fire burns hotter and more fully.

And yet the temperature continues falling, the fundamental concept of stillness rising. Light becomes less. Motion becomes harder. The world seems hazy, distorted.

She sets her power to creation, a continual release of energy, to counteract the freezing.

Shards of black ice lance for all of her opponents, hard enough to cause thunderous cracks and flashes of light.

Ellisaria breathes out a blasts of fire into a wall.

About a fifth of the shards, almost entirely the larger ones, get through - though they're now diminished in size, often less sharp. Still, they're going fast.

She'll meet the closest with more concentrated fire. For the rest, they'll have to dodge.

Her allies manage that with mostly successes.
