Yakumo's Monster, Ido

*Drip*

Droplets of water seeped from the twitching flesh corridor. It's as if I had entered the throat of an extremely large animal. My feets slightly sunk into the flesh floor due to its buoyancy.

There's no doubt that this is the mental plane of Yakumo.

I looked down towards my hand and tried to activate Chidori with the System, but it was impossible. After all, this mental plane is inside of Yakumo, and my small bit of chakra that had seeped inside of her isn't enough to use the Chidori.

I had expected to at least be able to activate my Chidori, but it seems that I was wrong. So, my plan of forcibly dragging out the monster had already failed before it began.

Kwop! Kwop! Kwop!

Sounds of chewing could be heard around the corner of the flesh corridor, and that caught my attention. Even if I won't be able to drag the monster out, I still planned to talk to the thing at the very least and try to aggro it out.

Slowly, my body transverse the flesh floor and before turning around the corner, revealing the thing that's making the noise.

That thing that I saw is currently wearing the exact same clothes as Yakumo, but it had a dried up body. It also had horns and an ugly sunken face.

It ripped the meat from the flesh walls of Yakumo's mental plane and chowed down on it before reaching up and ripping even more flesh.

I looked up and down the flesh walls, and it seems that I was mistaken. This 'corner' wasn't a normal extension of the flesh corridor.

The monster that's eating the flesh had dug a hole into the mental plane walls and consumed the flesh that it dug out.

"Ido." I said blandly to get the monster's attention.

"Hmmmmm?" Ido turned around while still chewing some flesh in its mouth.

It had crept into the mental plane of Yakumo, and it had been feeding on her. Since Yakumo couldn't control her own Kekkei Genkai, Ido had taken it upon itself to take her power and control it for her.

It had already begun its assimilation with Yakumo, and in time… it will be able to completely take control of Yakumo's body, becoming Yakumo in the flesh.

But one of the requirements for it to be able to take control of Yakumo's body is for it to consume all of her mental plane. Hence, it is eating away at the flesh walls.

"Who are youu!" Ido made a croaking noise and opened its mouth to exposed its sharp teeth and the half chewed flesh.

"You can call me lil fucker. I go here and there to fuck cute girl, beautiful girls, thick girls, and even monster girls. If you're a monster girl, Imma fuck you too." I took out my two middle finger guns and showed them to Ido.

I wanted to show it how much fucks I gave.

"?!" Ido dropped the meat that's on its hands. Even the meat in its mouth fell out, dropping onto the flesh floor.

It is a monster, and it has evil tendencies. However, the person in front of it even made it speechless with his nonsense.

"How… Do you know of my existence?" Ido came back from the uncomfortable silence and asked. It wanted to rush up right now and attack the person in front of it, but it wanted to know how its existence got leaked.

Yakumo's teacher Kurenai came here before, but she was easily defeated by it. After all, Kurenai had no power inside of Yakumo's Mental Plane. The only one who can wield the power inside here is herself and Yakumo.

Even when it met with Kurenai, it didn't expose its name. So, Ido wondered how this person knew.

"That's not important! What's important is that you might have a pussy, and I can maybe use you when I spread it open!" I stomped on a lump of floor flesh and pointed my middle finger towards Ido.

If I had a cape, it would flutter at this moment to give me a heroic cut scene as I declared my intentions.

The thought of fucking Ido really did come to my mind, but I threw away the idea. It's really so ugly that I doubt I'll be able to reach an orgasmic peak. Ido might not even be a girl, so I might even be wasting my time.

However, I believe that my Talk-no-Jutsu touched Ido's heart… just not in the same way that Naruto's Talk-no-Jutsu will touch other's hearts.

"If.. you don't want to talk… DIE!" Ido croaked this line before opening its mouth and throwing up flames.

"Genjutsu?" I muttered as I saw the flames rushing over to me.

My Sharingan activated and it promptly allowed me to be free of the Genjutsu. If I had access to more of my chakra like Kushina did when Naruto fought the nine tails in his Mental Plane, I would have been able to retaliate more.

However, that's sadly not the case. My little chakra that had seeped through Yakumo is only enough for me to keep the Sharingan open for this slight moment.

It automatically deactivated once it was used to free me from Ido's Genjutsu.

"In here… I am invincible." Ido cackled and opened its mouth once again, spewing out a wave of flame that flew outwards. It's only a genjutsu flame, but because it had access to Yakumo's Kekkei Genkai and chakra, it is able to manifest the genjutsu flame into reality!

"URGHH!" I groaned in pain as Ido's flame burned my mental body. The pain felt so real, and I felt like layers and layers of my skin burning off.

I wanted to leave quickly, so I swiftly told the monster: "Ido, come out of Yakumo and fight or I'll kill Yakumo and eliminate you with her!"

"..." Ido didn't say anything. It had the wait and see attitude. It didn't really want to go out because it's possible that it could die out there.

…

Yakumo felt her heart thump and her eyes shook, but she didn't know what had transpired inside of her mental plane.

So when Sasuke stood still and looked into her eyes with his Sharingan, she was a little weirded out.

"Fuck!" I cursed and saw that a little bit of my skin is starting to burn in reality. This was the power of Yakumo's Kekkei Genkai.

I hurriedly let go of Yakumo's hand and bit myself, activating Heal Bite to heal up the injury that Ido had placed on me.

"How did you get injured…" Yakumo was shocked when she saw Sasuke's skin burning out of the blue. He's also cursing at someone while looking at her…

"It's that bitch that's feeding inside of you that burned me. It's also the thing that killed your parents. You don't remember because it has been making you subconsciously forget those memories." I exposed Ido and brought out a kunai before sticking it right onto Yakumo's throat.

I don't really want to admit it, but my plan failed. So, I'm falling back to this method of threatening Ido out with Yakumo's life.

"I… I…" Yakumo felt overwhelmed. Everything that had transpired is already too much for her to render in her brain. Sasuke is even putting a kunai to her throat now…

She just froze like a statue. Her genjutsu powers hadn't been completely unsealed, and she couldn't do anything without her painting supplies.

"Come out, you bitch. Just one move and I'll kill you both!" I yelled at Yakumo, but I knew that Ido is listening.

But Ido didn't come out. It's as if it knew that I wouldn't kill Yakumo.

Hence, I decided that I might need to really do something else. It didn't sit right with me to just retreat right now.

I quickly calmed my mind and thought about what I can do to drag out that bastard that burned me. I thought about it over and over again… until it clicked.

I had the Mind Transfer Jutsu! If I took over Yakumo's body and mind, I would be able to gain the chakra that I needed inside of her Mental Plane.

So I smirked and said out loud: "Since you're not coming out, then this lil fucker is coming back in to show you the meaning behind my name!"

"Shadow clone!" I yelled out and a shadow clone of myself appeared next to me. It knew what I wanted to do and directed its hands at Yakumo before activating the Mind Transfer Jutsu.

"I'm coming back, Matha Fuckaa!!" I yelled and reactivated my Sharingan to re-enter Yakumo's mental plane.
