I don't own neither Code Geass nor Honkai Impact
"So... Who are you?" Lelouch, who was dressed in his white emperor clothing, asked a girl who seemed to be about his age with slicked back neck length black hair, and same shade of purple eyes.
"Well... I am you but far more dangerous." She replied in a confidant but haughty tone.
"What?" Lelouch asked her.
"Well dear brother, may I call you brother? besides reality is far larger then you realize, and your reality is one of the many worlds in the Imaginary tree, which I'd like to call Yggdrasil. Also you may call me Lucia." The Girl told him which made Lelouch look at her with a raised eyebrow.
"What?" Lelouch asked.
"Anywho brother mine, My story began somewhere after dear ol' Suzaku became a kinslayer and killed his father and Nunnally was killed in the initial Britannian assault of Japan, skip a couple of years a voice called out, and granted me powers similar to your geass of absolute obedience but at the same time wholly different, then I led the Resistance to successfully fight off the military, with me making the Soldiers commit friendly fire at the side, and went to Clovis for answers on Marianne's death, well from then on things go quite similarly to yours, other then the fact that I used my powers to have Lieutenant Colonel Josui Kusakabe, jump off of the 3rd story window and from then on the plans that I conducted maximized casualties and after taking Britannian throne and use it to my whims I maximized both the casualties among the military and Civilian targets. And in the moment of my death I released the Collapse that would plague Humanity for as long it existed." His female counterpart explained to Lelouch.
Lelouch felt deeply unsettled by the fact that she spoke so casually about the loss of life, heck Lelouch may have been a callous and manipulative individual whose entire plan costed a lot of lives to the point some may call it genocide, but they ultimately came into fruition and the world achieved the peace he so desired and that Nunnally to live in a better world, and was willing to give his life for that price.
But Lucia was almost... Giddy in the most twisted way, she didn't care of the lives that died for her plans, her plans were the only thing she ever cared about and she didn't care if a million died, but the fact that those plans caused were all about causing as much casualties as possible made her feel happy with herself, as if she wanted those deaths to happen.
"Why?" Lelouch asked Lucia.
"Why, what O' Brother mine?" Lucia asked him.
"Why did you cause all those casualties?" Lelouch asked Lucia who merely smirked.
"Why indeed, well the answer isn't some deep and philosophical sentence O' Brother mine, I caused those casualties simply because I could, I didn't cause them because I had some grand plan for world domination or anything having a deeper meaning. I caused all those deaths because I wanted them to happen, just like I erased the existence of Marianne and Charles and in the process I ripped out my Human heart and went on a Genocidal spree, while at the same time using the throne of Britannia on the side." Lucia answered recalling those acts of violence with fondness in her eyes.
But Lelouch had one thing his mind.
"What happened to her to make her like this murderous monster?" Lelouch wondered to himself.
