The Tournament to Stop The Apocalypse, A Hololive Fan Story

Memento Mori

"I'll knock some sense into you, just you wait!" Kiara shouts, "That'll only make me more resistant!" Calli replies as she charges at Kiara.

"What did they just do?" Moona asks, "I know less about the gods than you do..." while staring down Mumei begins, "Callis current form is her sign of getting serious, definitely not her peak, but she's getting there. It's an armor she developed while training under the Grim Reaper, she decided her strength wasn't enough and she wasn't learning fast enough from the Grim Reaper. So instead, she went to the depths of the Helheim, to learned from the strongest gods that roam. staring with Hades, she learned from him to conjure The Souls of The Damned from The River of Styx. Next she went to Hel, and learned more about necromancy, or manipulating maybe age or disease, and even the ability to turn someone to rot. She continued her adventure in Helheim encountering gods and demons til eventually she reached the deepest pit, and managed to defeat and seal Thanatos within her scythe, she practically absorbed him and thus his powers are now hers." Mumei explains, "As for Kiara, she simply unleashed more of her power, as you should know she's summoned here from another dimension of eternal beasts and she is one, known here as a Phoenix. Her human form holds back an insane amount of power, she's likely 70% weaker in her human form than her real one."

Callis scythe blade lifts up, like a spear, then Calli dashes forward with it to her side and thrusts it into Kiaras abdomen. She smiles and pushes it further in, widening the wound. Kiara screams in pain and her flaming wings rise then stab down at Calli. Calli looks up at the wings then jumps back. Kiara looks to Calli and flies forward with her two wings pointed at her. Callis scythe blade returns to its normal position and she widens her stance holding the scythe with one hand. She pushes it forward and begins to spin it In front of her. Kiara begins to rotate her own body making a drill and the two collide. Calli begins to slide back while crumbling the ground. She grunts and her armor grows off her body just a tad and she summons two arms from behind her back attached to her skeletal armor. It's hands close to  fists and slam down at Kiara who uses her wings to dash back quickly. She quickly regains composure and slices at Calli with her wings but Calli doesn't even flinch as the armor completely blocks it. Calli smiles as Kiara stares in shock. She snaps out of it as the arms attempt to grab ahold of her. Kiara dashes around Calli sneaking in small strikes with her sword as Calli stands still attempting to grab Kiara with the skeletal arms.

Finally Callis threatened enough to dodge one of Kiaras strikes and manages to catch her off guard enough to grab her with one of the arms. Kiara struggles to get out of the grip but can't manage to even move an inch. Calli brings her in close, "you're embarrassing us both. I'm done waiting for you, either fight or die." Calli says while staring with a serious look, "I don't want to hurt you Calli! Why can't you just give up!?" Kiara replies desperately, "if I gave up now, I wouldn't have any pride left. Now that I know I can win without you coming back to life to bring it to a draw again, I can actually defeat you, and remain the strongest!" Calli shouts, "You sound like a little kid! If you wanted to fight me and win without me resurrecting then you could've just made a fight between us that didn't allow me to continue fighting after one death!" Kiara explains
"And what? Just allow you to let me win!? There has to be something like this on the line for rules like this to work! And now I have an opportunity to make you bow!!" Calli shouts as she raises Kiara into the air. Kiara looks down to Calli and sheds another tear, "There really isn't another way..."

Calli begins to squeeze down on Kiara but Kiara's eyes glow before she unleashes a strong pulse that at the center melts the fists away as Calli jumps back. The rest of the surrounding area is engulfed in flames and glass melts away. Kiara remains suspended as her wings grow larger and further from her body the raise vertical and above the buildings flatten again. What appears to be a beak chomps down on Kiara from behind and a great flame forms into a head of a beautiful bird. The flame spreads and connects to the wings as the bird rises out of the city and Blocks out the sun. The flame solidifies and The Great Phoenix arches it's wings as it screeches. Unleashing another pulse of heat that melts away the city block below her.

Calli smiles as she looks up at Kiara, "took you long enough..." she chuckles, "Now it's my turn!!"
Calli's armor expands and vanishes as a blue flame surrounds her. The ground begins to shake and from under one of the buildings to Calli's left, a large arm reaches out, destroying the building. And to her right another arm reaches out. They lower their hands and crush another building as shoulders and a back rip through the road behind Calli. The arms push up as the figure stands and Calli rises above the shoulders. And finally the giant skeleton begins to pull itself out of the hole it just created. As it rises muscle and flesh form, and then armor wraps the arms and a chain runs across the abdomen, attaching coffin-like shoulder pads. Finally a hood rises above Calli and a skull shuts In front of her as the eyes glow a deep red. It reaches behind its back and pulls out a scythe attached to a chain.

"I've been waiting to use this..." Calli says as Kiara just lets out a deep growl.
