Male OC X Kimetsu No Yaiba / Demon Slayer

Rising Sun

Previously...

Geez, what's wrong with him? He keeps on glaring. Did my words get through his head or not? Did I follow the wrong step from the site?

Stepxxx: If you notice that someone is acting weirdly or kinda possessive towards the one under your care, be alarmed and take necessary action.)

Necessary action? Like what? Court? Demons ain't got no court. I did try to provoke him but I'm lost now. Did it even work? From the look of his eyes, I can tell that he didn't get it.

*Stares at Katsuki*

In Lord Lucky's eyes-

 (System: Identifying target...

Name: Katsuki

Race: Demon

Title: Creepy Stalker

Status: Fatigue(Mental: Incurable Obsession towards Oreki/Yoru)

etc...)

This... I never thought I would see 'incurable' on his status. Handling him might be harder than I thought.

Parenting: Obtained after a sequence of a headache thinking on how to take good care of someone that can be considered as your heir-)

SHUT THE HELL UP SYSTEM! I'M TRYING TO FOCUS!

...

The land is in a devastated state. I grip my stomach where my chakra pool is almost empty. I stabbed the ground with my sword to give me the support to walk forward. My head is dizzy but I refuse to give it up just yet.

"You've done well." A voice spoke to me. The smoke cleared and all I see is Kokushibou's dissipating body. "You've made me realize something. This is not what I've dreamt to be. I never wish to become such a terrible monster, but my thirst for straight had blinded me." He continues. "With this, I accept my loss. Take this." He held out his sword. "Once I turn to ashes, this sword will turn to its normal form. My wish is that to make an altar with my brother's sword placed right next to mine."

"Kokushibou..."

"I just hate it. Whatever we do, I always felt distant from him. Our skills, levels, mastery, and everything. I failed to see his inability to express himself. His weakness that I didn't notice until it was too late. I entrusted you with this, Yoru." And with that, Kokushibou closes his eyes, turning them into ashes.

Oreki watches as his favorite character dies right before him. "Haa..." Oreki fell onto his knees, gripping his head. The dizziness worsens, but he still slowly dragging his own body to grab the sword. "Kokushibou's... Sword... Must... Grab it..." His hand gripped the sword tightly. His breathing is not in order. "Ah... I'm... Out of chakra." Oreki slowly closes his eyes. His head felt cold meanwhile the ground just felt so comfortable.

*Drip*

Oreki's alter ego smirked inside his bloody lake cave prison. "Well, will you look at that? He's running out of energy." A thin red aura surrounds the figure as the lake produces ripples and the dead Sakura tree branches shake. Unfortunately for him, some dark chains with red highlights emerge from summoning circles that are activated. "He knew at some point that I'll try to take over this body huh? That demon lord is really cautious despite seemingly carefree."

Alter sighed and deactivates his demonic energy, resulting in the chains that bind him to disperse into molecules. "Oreki can't use this energy yet? I mean, we ARE the same person, to begin with. I can't believe he still depends on chakra." Should I let him die? But he is ME. That would count as suicide. Reason for death... dying in the honorable fight for the sake of humanity? That trash avoid me like a plague and if I die here I'll end up as their savior? Ugh, DISGUSTING!
