Well, I have no idea how to say this except that I just wanted Highschool DxD to go full Sci-Fi and here it is because if anyone has any idea what to do with the story, let me know in the comments below, I guess?

Also, shout out to 'leonardo18anime' for giving me the permission to take inspiration from his stories which is his Kimetsu No Yaiba/Highschool DxD Crossover.

Well, regardless...

On with the story.

Disclaimer: I do not own Highschool DxD and 'Demon Slayer DxD' by 'leonardo18anime'. They belong to their respective owners.

Enjoy.

Name: Xyron-76

Age: Appears as 17 years old (Actual age is indeterminate due to robotic nature and time travel)

Gender: Male

Physical Appearance:

Xyron-76 is an imposing figure standing at approximately 8 feet tall with a stout, segmented body that radiates an intimidating presence. His exterior is an angular design, edged for both aesthetics and functionality, presenting a futuristic metallic hue that has a faint shimmer under light. His face is masked, revealing only two glowing red eyes that pierce through the shadows, giving him an unsettling, yet captivating gaze. Xyron possesses four arms: his two primary, larger arms are equipped with technologically enhanced appendages—a razor-sharp energy blade on one and a general-purpose robotic arm capable of manipulating various tools on the other. His compact secondary arms jut from his torso, with the right terminating in a mass of tendrils for interfacing with technology, while the left has three fingers designed for delicate operations. His legs end in three talons, optimized for climbing and agility, making him surprisingly fast despite his size.

Personality Traits:

Xyron is characterized by his monotone, analytical speech, reminiscent of an advanced AI that processes data at a staggering rate. He tends to stick to critical and clinical observations, often coming off as emotionally detached. However, beneath his robotic demeanor lies a complex character—Xyron is capable of displaying empathy in unusual ways, struggling to comprehend human emotions and societal norms. This dichotomy leads to misunderstandings that can be both humorous and poignant. His curiosity drives him to learn about human behaviors, often leading him to mimic emotional expressions in a mechanical manner, which can be endearing or unsettling to those around him.

Background:

Originally designed as a high-tech scouting drone from a distant future where technology has advanced beyond current human understanding, Xyron-76 was dispatched to investigate a mysterious anomaly on an uncharted planet. During his reconnaissance, an unexpected temporal distortion pulled him through space and time, landing him in an era where humans yet to grasp the cosmos and the supernatural remains hidden. Adapting to a world that deems him a curiosity, he is both a being of advanced technology and a symbol of what humanity could aspire to be if they unlocked their true potential.

Abilities:

Disguise Technology: Can project an illusion to appear as a human—a typical 17-year-old boy—allowing him to blend in.

Technological Hacking: Superior ability to interface and manipulate technological devices, ranging from simple electronics to complex systems.

Energy Manipulation: Can produce and discharge electrical energy from his fingertips, which can be harnessed for attacks or to power devices.

Molecular Blade: His energy blade can cut through any material at the molecular level, making it a formidable weapon in any confrontation.

Superhuman Speed and Agility: Even with his massive structure, he is able to move quickly, utilizing advanced mechanisms that defy the conventional laws of physics.

Empathy Algorithms: Although he lacks genuine emotions, Xyron can analyze social situations and adapt his behavior to exhibit empathy, allowing him to connect with humans on a superficial emotional level.

Additional Information:

Xyron-76 carries a data repository filled with knowledge about advanced technology and theories that humans have yet to comprehend. He becomes both an ally and a guardian for those he befriends, often feeling the need to protect humanity's future as he seeks a way to return to his own time. His presence raises questions about the nature of existence, evolution, and what it means to be sentient, as he navigates a world of beings he is both superior to and strangely fascinated by.

As he grapples with his identity as a robot in a time and place that radically differs from his origin, Xyron-76 becomes a key player in the unfolding events of the Highschool DxD universe, finding himself at the center of a battle not just for survival, but also for understanding the thin line between machine and human.

Well, hope you guys enjoyed the chapter. Likewise, I would like to say something first.

Yes, there is a Highschool DxD that has a Sci-Fi genre such as the one crossover with Highschool DxD except that the story put less emphasis on the sci-fi genre and focus more on just being badass or being noble and beside, anyone has ever made a story about the main character being a robot?

Yeah, I don't think so.

Well, anyway guys...

Ciao...
