And we are back with another script based oneshot idea. This time it's demon mode rather than immortal from the past.
This one is shorter than the other one I did, but that will be explained in the bottom author note so don't forget to read that.

Hope you guys enjoy.

LADY TAMAYO'S RESIDENCE

Tanjiro and Nezuko face off against Susamaru and Yahaba.
Susamaru summons a temari ball into each hand.

Susamaru (playful): "well don't this look fun"

Yahaba (annoyed): "stay focused Susamaru and don't you dare get any dust or blood on my clothes"

Susamaru glares at Yahaba.

Susamaru (angry): "loosen up you boring bastard"

Susamaru turns back to Tanjiro and launches her temari balls.
Tanjiro tries to slice the temari in half.
The temari launches off the side and rebounds into Tanjiro's arm.
Yahaba backs off to use his blood demon art.

Susamaru (playful, vicious): "you're about to be slain by one of the twelve Kizuki, you should feel honoured"

Tanjiro (surprised, worried): "you're a kizuki?"

Susamaru (sadistic): "damn right I am! Now die"

Susamaru launches even more of her Temaris.
Yushiro loses his head.
Nezuko chases after Yahaba.
Ino enters the area.

Tanjiro (courageous): "I am demon slayer Tanjiro Kamado, rank mizunoto and I will slay you"

Susamaru (joyful): "like you would ever be asks to slay a kizuki, now let me fucking kill you"

Susamaru launches her temari at Tanjiro's head.
Ino jumps in the way and catches the temari.

Ino (serious): "now now, none of that. We wouldn't want anyone injured now would we?"

Susamaru is shocked.
Tanjiro, Tamayo and Yushiro are confused.

Susamaru (angered): "Who the fuck are you? I can smell you are a demon, so why are you protecting this human scum?"

Ino just smiles in return.
Susamaru tries to fire another Temari but Ino used his demon blood art.

Ino: "demon blood art - demon cells: weighted body"

Susamaru stops moving.
Fear fills her eye.
Everyone else stops and stares in complete surprise.

Susamaru (scared): "how?! I can't move, how are you doing this?"

Ino: "I have command over demon cells. Even more than that upstart coward of a demon Muzan"

Susamaru (furious): "how dare you. I will fucking kill you, rip you limb from limb for talking like that about the master"

Ino stands amused.

Ino (vindictive): "that thing you call a master is nothing but a coward and a manipulator. I heard how you said you were a kizuki, yet you miss the kanji in your eyes. Whys that I wonder"

Susamaru (annoyed): "I am a kizuki! He told me, he promised me. You have no idea what you're talking about!"

Ino (calm): "he lied to you Susamaru. If you were a kizuki, you would have the kanji denoting you as such in your eyes. He has done nothing but lie and manipulating everyone around him since he became a demon. You and the rest of demon kind are nothing but pawns for him and his goals"

Susamaru (enraged, doubt): "you're lying, that's not true. I don't believe you"

Nezuko returns with a battered Yahaba.
Tamayo uses her demon blood art to knock him unconscious.
Ino stares expectingly at Susamaru.

Ino (calm): "think on my words and you'll see the truth"

Ino knocks out Susamaru.
He turns around to face Tanjiro and the rest.

Ino (amused): "Tanjiro Kamado, Nezuko Kamado, Yushiro, Lady Tamayo" - bows slightly - "it is nice to finally meet you all"

Tanjiro (confused): "how did you know our names?"

Ino: "we have a mutual connection in the form of Ubuyashiki"

Tamayo (curious): "may I ask what your name is?"

Ino (shocked, abashed): "ah yes, I forgot that didn't I? My name is Ino"

Tamayo is shocked.
Nezuko tilts her head in curiosity.
Yushiro and Tanjiro just nod in greeting.

Ino (amused): "you looked shocked about my name Lady Tamayo"

Everyone turns to Tamayo.
Yushiro looks both confused and agitated.

Tamayo (regretful, awed): "back when I was under the control of Kibutsuji, that name, it was the only thing that he seemed to actually fear"

Ino cuts his thumb, letting his blood leak into his hand.

Ino: "that's because my blood is the opposite of his in several ways, the most important being the fact my blood can override his control and block out the curse"

Ino drops some of his blood into Susamaru's mouth.
The sun starts to rise.

Ino (calm): "now I feel we should get inside before anyone feels the negatives of the sunlight arriving"

Everyone heads inside and gets ready for what is highly likely to be a long and confusing conversation.

Okay everyone, that was my script for a demon king Tanjiro. Now obviously, this is written in the POV of an OC of mine, but the actual fanfic (if you guys decide you want it) will be from the perspective of Tanjiro and will not contain this OC at all. All the abilities and such will be transferred over to Tanjiro in the real fanfic though.

Now, there are 2 reasons this was a really short script, especially when compared to the original Hashira. 1 of these reasons is because there will be another chapter of this, which will be a teaser/taster of what the actual fanfic would be like. The second reason is because it has been a real pain to get this written and published. Nothing about writing this has gone to plan, from the layout deciding to erase half the work to mixing up where the sentences are supposed to be, it's been a right old journey to get this written up and published on the sight.
luckily as shown, I have been able to salvage it and get at least part of it written and posted.

Now as I said before, the true fanfic won't contain an OC so this script isn't really important to what the fanfic will be like, that will be shown in the next chapter.

Of course, if you want me to post this as an actual fanfic (the Tanjiro version) then let me know. Whether that's through a review or a PM, I will read it and get started on writing it in full as a true fanfic.

Hope you still enjoyed this and stay on the lookout for the second part of this.
