Dangling their legs casually over Amakumo Peak's cliff, two teens look on at the shore below.
"To think we'd be going into the fight of our lives together instead of against one another. It's relieving in a sense."
"Every fight we've gone into has risked our very lives. Who knew everything would lead up to something like this."
"I don't think anyone could have predicted things would turn out like this."
"Looking back, it feels as though our first battle against one another was so long ago."
"Yeah... It certainly does. But things are different now. Both sides have finally achieved peace with one another. I'm just grateful for finding others who wish for peace like myself. Seeing friends dear to us get hurt is something no one likes."
"Friends?"
"Yeah. Friends. Did you think I said something else?"
"No, it's just surprising that's the term you use for the girls is all."
"Hey, I have male friends too aside from you, ya' know! It's just that Hu Tao, Ganyu, Eula, Ayaka, Sara, and- Ah, you ass!"
"Haha, sorry. I couldn't help it. Teasing each other without a care in the world. Moments like these I miss doing with Lumine."
"Heh, well you can celebrate after you beat her."
"And you Kazuha."
"I remember my first experience with my visions. It's so clear now compared to back then."
"Not that long ago you had amnesia."
Yeah... Serei Island... It's ironic. The very place my journey began is the location of the final battle."
"There's only one difference compared to our previous battles."
"It's just you and me. No army behind us. No Qiqi at my side or Paimon cheering you on from a safe distance."
"Haha, she certainly is good at that."
"Heh,yeah..."
Taking sight of their awaited guests, both get to their feet.
"Hey, Aether."
"What is it?"
"When we get back, let's get that earful from the others together. All of us." Relon says raising an arm.
"... Yeah, that's a promise." Aether responds bumping with his own.
Jumping off the cliff, Relon releases an icy mist conjuring a ramp as they descend to the bottom. Jumping off, both take sight of the new individuals.
"Took you two long enough." Relon greets. "I was getting tired of waiting. Ready to settle things, Kazuha? Why not give one of your famous haikus before we start?"
"Death is a gateway. For some, to life- some, to death. We all pass this gateway."
"Meaningful as always. Too bad, none of us are dying."
"Death is only a fleeting escape from this reality. Relon, surely by now you've grasped that."
"The only thing I've grasped is that I have to beat you. Same as always."
"Lumine, it's not too late!"
"Aether, stop. The way we used to be has long since passed. We've both grown ever since coming here. If you want to make me listen, then beat me! Or are you going to freeze up like you have in the past?"
"... No. This time, I'll take you down. We'll free the two of you from the evil plaguing your souls!"
"It is quite fitting." Lumine speaks withdrawing her sword, the air beginning to swirl around them. "A battle between siblings. Yet the winner will truly take all."
"That's not going to happen! We'll make sure of that!" Aether proclaims withdrawing his own sword, the gusts of wind increasing in acceleration.
"Just as Lumine proclaims, our bout too is destiny. Dual visions at odds." Kazuha quotes, the thundering clouds rumbling as if in discomfort. forming his blade before relinquishing the sharp weapon from its sheath."
"Haiku speech aside, when we first met, I didn't know the first thing about diplomacy, war, love, let alone how to fight. Yet, you knew all of these things, Kazuha. That's why... I want to experience all there is in this world! And you're going to be a part of it!" A single bolt of lightning strikes as Relon's right hand surges with electricity.
Focusing all of his power into his widened palm, his left hand reaches to begin pulling something. With a boom of thunder and lightning strikes throughout the island, Aether can only look in a mixture of awe and shock.
"Relon's that's...!"
"Yeah... The Musou Isshin." Relon reveals above himself catching his breath. "Guess she was right after all..."
"You have no right to use such a sacred weapon!" Kazuha snaps, wind and electricity encompassing his body.
"Seems I sparked a nerve. Get it, Kazuha? Those were the first words I spoke to you!" Relon's red eyes and black hair changing to snow white. "A Cryo instilled with Electro!"
"Your words are meaningless! We've prattled on long enough. Our duel of fate is upon us! We'll settle once and for all who is the superior Electro!" His red eyes shining bright for lightning to strike the surrounding land and thunder to roar in anger.
"He is right. We have no need to speak any further, Aether. We'll let our actions speak how we really feel, bro!"
"I'm not giving up on you, Lumine. Not now, not ever! So don't expect me to hold back, sis!" Both pairs of golden-yellow eyes radiating a bright color as does the wind around the two.
The clashing currents showering the entire area in its ferocity as destructive tidal waves forms and clouds nearly pitch-black fill the sky.
"You know, a part of me is thankful for not using the polearm seeing as we all are using swords." Relon gives a chuckle ignoring the impending destruction around the four.
"I told you, no more talk! Only fight!" Kazuha roars, he and Lumine launching a combined attack of wind and electricity.
"You should know better than anyone!" Relon retorts, he and Aether countering with the same attack for the colliding elements to push the two sides away from one another. "I've never been good at taking orders let alone staying still! Like a bolt of lightning, I move to wherever I am drawn and do as I please! After all..." Both sides charge. "I am Ei's Chosen!"
A/N: This is an OC x harem consisting of Hu Tao, Ganyu, Ayaka, Eula, Sara, And Ei with Qiqi as Relon's younger sister. Enjoy~.
