Kuroto observed the two pairs of Byakugan in the Eye Sockets and confirmed that they were indeed Byakugan, at least, from the outside nobody would be able to distinguish whether they were cloned or original.
But for Kuroto who has the Tenseigan, he could feel that these two pairs of Byakugan were semi-finished, or better yet incomplete.
And this didn't surprise him.
With the presence of 'Dead Demon Consuming Seal' that seals the soul of the target within the belly of the Shinigami, 'Impure World Reincarnation' that summons the soul of the dead to the world of the living, and so on, such soul related Jutsu have come out one after another in the Shinobi World, therefore, the question whether the souls exist isn't debatable.
Although the presence of Souls has always appeared in the form of Chakra, like the presence of Uzumaki Kushina and Yondaime-Sama's Chakra sealed inside Uzumaki Naruto, there is no doubt that Chakra itself doesn't represent the souls, nor is it equivalent to the soul.
What Kuroto thinks is that the Chakra is merely a carrier for the Soul, but the true essence of a soul should be a unique spiritual symbol.
This reasoning is understandable as it also explains why everyone has a different Chakra signature.
And what the Clones on the test benches lack is the unique spiritual symbol.
Therefore, the Byakugan pair within the eye sockets of the two clones are incomplete, they are just a pile of cells tissues with the Byakugan characteristics, that lacks a spiritual symbol.
This is why the research value of these incomplete Byakugan isn't that high.
In fact, this is also reasonable, if cloning alone could perfectly replicate everything, then Orochimaru wouldn't be madly chasing after the geniuses of the Uchiha Clan, for their Mangekyou Sharingan.
He could just somehow obtain their cells and create clones then use the 'Living Corpse Reincarnation,' but since he didn't do that, therefore it does give some explanation.
But Kuroto wasn't disappointed by this finding and continued the tests to record all the data.
These two clones may not be that useful for others but these soulless clones are exactly what he needs the most, thanks to the new ability of the Tenseigan that he has figured out.
It was during the Chakra transfer to the Kazekage puppet that Kuroto managed to accidentally discover that his consciousness could temporarily take over the puppet body of the Sandaime Kazekage.
This discovery made him understand that the Tenseigan has another very useful ability!
In his memory too, Otsutsuki Toneri seems to have used this ability by temporarily transferring his soul to a puppet and come to Earth to send an invitation to Hinata, but when Naruto discovered it, Toneri withdrew his soul and abandoned the puppet.
To a certain extent, this ability of the Tenseigan is very similar to the Forbidden Technique of Living Corpse Reincarnation developed by Orochimaru.
However, the Soul Descend ability of the Tenseigan is much easier to use with fewer constraints. Not only can one transfer his/her soul to other bodies and puppets but it is also possible to withdraw them at any time.
And using this ability of the Tenseigan, Kuroto plans to cultivate the six clones perfectly and fuse them into his main body with the Chimera Technique.
Otherwise without the Tenseigan Soul Descend, simply relying on cloning will not cultivate the perfect clones that would fit the soul in a true sense.
With that thought, after recording all the physical indicators of the two clones, Kuroto carefully compared the data between the two, and unsurprisingly enough both the clones had relatively similar data.
There was no significant difference in strength or weaknesses.
Nodding in appreciation that both the clones are somewhat acceptable, Kuroto named them Clone-A and Clone-B respectively.
With that out of the way, Kuroto sat cross-legged facing the two test benches and used the Tenseigan Soul Descend to transfer his soul to the Clone-A.
As soon as Kuroto's eyelids closed, the Clone-A lying naked on the Test Bench opened its eyes.
Sitting up with the support of the Kazekage Puppet, Clone-A opened its mouth, as if it wanted to say something but all that came out were some incoherent voices without any meaning.
After a while of continuous trial, finally, some recognizable words came out of its mouth, "Really… it feels quite awkward!"
Undoubtedly, Kuroto's soul was currently occupying the body of the Clone-A, in other words, currently, the Clone-A has become Hyuga Kuroto.
After getting up from the test bench again with the support of the Kazekage puppet, he staggered a few steps before he could stand firmly.
Walking was still very difficult for him initially but gradually; the body movements became easier and the initial strangeness disappeared.
After getting used to this new body, Kuroto wore a lab gown while thinking to himself, 'The test data is really not as accurate as of the real feeling of the body, the Tenseigan Soul Descend is more useful to recognize many minor details.
After he was dressed in a blue lab gown, Kuroto walked towards the mirror and carefully looked at the appearance of his eyes in the mirror.
From the outside, there doesn't seem to be much change in the physical appearance of the Byakugan, but Kuroto knows that the pair of Byakugan in his eye sockets is no longer incomplete as before.
Byakugan…
As soon as Kuroto transferred the minimal Chakra he could towards his eyes, the veins and meridians around his eyes bulged and his field of vision also changed entering into a three sixty-degree Byakugan Vision.
'It truly is because of the Soul descend…'
As Kuroto expected, because of the Soul Descend, the Byakugan pair in the sockets of Clone-A was no longer incomplete, but real and complete now.
In order to confirm his guess, Kuroto hurriedly walked towards his main body and gently opened its eyelids.
"This…?"
He was surprised to find that the Tenseigan in his sockets has lost its glow and reverted to the state of the Byakugan. This is obviously strange as the Tenseigan was obviously active before Kuroto used the Tenseigan Soul Descend.
Rubbing his chin, Kuroto thought for the possible reason for this, 'Even my main body is unable to keep the Tenseigan active after losing the soul? Then is my Tenseigan part of my physical body or Soul body?'
In order to understand this, he hurriedly conducted some tests with the Clone-A body.
After conducting these tests, Kuroto concluded that he could not activate the Tenseigan, neither was he able to use the Rein Interaction nor was he able to use the Tenseigan Chakra Mode while in the Clone-A body.
And the advanced techniques like the 'Golden Wheel Reincarnation Explosion' and 'Silver Wheel Reincarnation Explosion' need not be mentioned because they can only be used in the Tenseigan Chakra Mode.
There seems to be only one Tenseigan ability that he can use, and that is 'Soul Withdrawal.'
"No wonder Naruto was easily able to defeat the puppet Toneri used to descend on Earth" – muttered Kuroto in understanding.
At this moment, Kuroto has confirmed that his Soul has a fraction of the Tenseigan, but his soul needs to be in the main body to be able to actually use that power, that is to say, the soul and the physical body combine together to form the Tenseigan, so without a materialistic physical body, it is pretty difficult for him to use the Tenseigan.
After understanding this, another doubt arose, "If the Tenseigan pair is removed from the eye sockets of the main body while the soul is still inside it, will the state of the Tenseigan remain active at that time?"
