Chapter 6

Kuro:' It's not like I am very attached to my humanity, and even the bad sides of both cursed energy and Satan bloodline can be nullified by the skill mental fortitude, I just need to train it, the Zanpakuto will also most likely become my main weapon.'

Just to be sure I wait until night to absorb the Satan bloodline, while for the rest of the day I experimented with the power-cursed energy.

Just like the description said to use it I must feel negative emotions, which will fuel the cursed energy, at first someone will think that negative emotions would be rage, but negative emotions can also be sadness, despair, sorrow, and thanks to 19 years of depression, ADHD, and repressed rage, I have tons of negative energy.

I begin to rethink those moments while making sure to not be overwhelmed by them, suddenly black and white smoke begin to cover my hands, even only doing this small task is asking a lot of concentration, I slowly try to attune myself to the feeling of this smoke, when I am sure am I able to control it, I continue to spread it until it reaches my shoulder, over that point and I would be overwhelmed.

I stay like that for a few seconds, and while I am still in this state I open my status to see what kind of upgrade I am receiving, and my Strenght had raised from 11 to 21 and my Endurance from 11 to 16, so a whole +15 points, and for a skill, still under level 10 it's a big upgrade.

I deactivate the coating on my arms, and I do the same for my legs, which raise my Endurance by 5, and my Agility by 10,

I wanted to try coating my brain and heart, but I am not sure if it would cause any type of damage, even more, now that it is still under-leveled.

I spend the rest of the day getting used to this energy, and by the time night came, it reached level 11, and my Intelligence, Strenght, and Endurance raised by 2 points, mostly because I "trained" while using the energy, and by training, I just mean walking around and rasing toys.

When night finally arrived, before assimilating the bloodline, I took out the Zanpakuto.

The sword is a normal katana, at least for now.

*DING*

*The host has come in contact with a soul weapon, does the host wish to fuse his soul with the weapon?*

YES/NO

I instantly click yes, and receive some other notifications.

*DING*

The would weapon is scanning the host's soul

The host soul is strong enough to fuse with the weapon.

The soul weapon fuse with the host soul.

The soul weapon characteristics, name, effects, and side effects changed.

To summon the soul weapon host just needs to wish to come out

I do just like the system said, and wish for it to come out.

And suddenly in my hand, a sword, at least 3 times bigger than me, but still weighs like nothing, pops out.

The sword is a black massive longsword, with hooked parts, and a hooked guard, on its blade there also is red engraving, which results due to the blade being completely black. (Search sword of Kas from critical Role for a picture).

Suddenly it's staus panel open in front of me.

*Item*

Zanpakuto (Wakizanashi)

Rank: Growing

Current name: Yami ga kuru (Darkness shall come)

Effects: Boosts all darkness-related powers, deals physical and soul damage, drinks blood from their enemies to become stronger and sharper.

Side effects/Restrictions: None

Since its shape is way too long for me now I decide that I train it at a later date, now it's time to fuse with the demon bloodline.

Not wanting to destroy this place, I decide to use my own shadow to create a ball all around me, which will prevent all possible flams that come out of me to not getting outside.

I click on the bloodline.

*DING*

A very important is about to happen, are you sure to want to change your current race Evolved Human(Quirk type(, to Evolved Nephilim (Quirk type).

YES/NO

I slowly click yes, and before I could feel anything, everything blacked out.

In a world covered with dark and blue fire, with shadows as big as skyscrapers, and a cold wind strong enough to tear humans apart, there we can see Kuro, implying enjoying the hotness and coldness of the climate, while looking at the shadows as if they are puppies.

???:'' Enjoying the view?''

Kuro:''Very much, you must be my Zanpakuto soul.'' I say while turning towards the voice.

In front of me, there is a complete black copy of me, which even if colored like this is still detailed enough to look like me.

Zanpakuto:'' Yeah, and as much as I would like to spend my time with you, your body has already evolved and is about to wake up.''

Kuro:'' Well, until next time I guess then.''

Zapakuto:''Be sure to meditate sometimes, it can help you enter this world.''

And I vanished from this world.

.

.

.

When I woke up, all my muscles were, aching, I looked around and saw my shadow still there, I felt relieved, I returned the shadow to its normal state and looked at my body to see any changes.

The first visible thing is that my height went from 50 cm to 1.10 meters. a tail popped out of my ass, like a prolongation of spinal bone, and laslty some small horns began to pope out of my head, fortunately, they are easily covered by my hairs.

No other physical change happened, so my next step is to control my status, and when I opened it, oh damn if it changed.

But since I am an asshole I will show it next time, bye.
