Kakashi nodded, processing all the things that the system told him and asked, "Doesn't that mean if my Chakra Reserves reach and surpass Ten-Tail's reserves in future, I will have Ōtsutsuki's Bloodline or traits?"
[Negative. Just alone housing a huge amount of Chakra doesn't make Host an Ōtsutsuki.]
[However, Host's physical and spiritual state will change to be something close to that of Ōtsutsuki's, but wouldn't have white pale skin, Byakugan, horns and other characteristics of Ōtsutsuki's and their powers.]
Kakashi decline his head, nodded, and said, "I definitely don't want horns anyways. So, that doesn't matter. But having vast chakra makes my Yang and Yin Release also grow, does that make the ocular power of my Sharingan comparable to or higher than EMS? Like no blindness from the use of the eye's power?"
[Affirmation. Continuous increase in Yin Release Chakra specifically, which is Spiritual Energy required for Dōjutsu.]
[With a continuous supply, it will nourish Host's Mangekyō Sharingan, preventing the eye from experiencing the strain, however it wouldn't make your eye exactly an Eternal Mangekyō Sharingan.]
Kakashi nodded, and muttered, "So, this will be similar to the case of Obito, who also not suffer blindness in his Right Mangekyō, but his is because of potent Yang Release Chakra from Hashirama's cells, but in my case it will be a continuous increase of my own Yin Release Chakra."
[Does Host have any other queries?]
Kakashi put his hand on his chin and thought, before asking, "Yes, If the ocular power of my Sharingan will grow, would that also give me access to other abilities of this eye? Plus I really got access to one more just a few days back, but what about others if it has, like even Susano'o?"
[Affirmation. If Host's Mangekyō Sharingan has other abilities, then he will definitely gain access to them. Susano'o is also an ability of every Mangekyō Sharingan pair, and Host can also gain access to it with both eyes.]
[However, Host can't use it with one Mangekyō, while Shisui Uchiha was able to use Susano'o with one eye. Because the real owner, Obito, not having both eyes to create the link for Susano'o when his Mangekyō Sharingan Awakened, which awakened in two different person's eyes.]
Kakashi was surprised a little but not much, and mumbled, "Shisui indeed able to use Susano'o with one Mangekyō, but Obito was never shown to use it with his one Mangekyō eye in anime, despite his Sharingan's ocular power being higher than that of Shisui's. So, it all comes to be the link, which Obito didn't get because his Left Sharingan was in my eye socket, when he Awakened Mangekyō. Then doesn't that mean, even with higher ocular power of my Sharingan, I still can't be able to use Susano'o in future."
Kakashi thinks a little more and asked, "But does that mean Danzō can use it, he also has Shisui's Mangekyō, whose ocular power is higher with Hashirama's cells."
[Negative. Host can not use Susano'o without a pair, because Host isn't the real owners of the eye. Same is the case with Danzō, who has stolen Mangekyō of Shisui Uchiha.]
[However, Host have different circumstances, with an increase in spiritual energy, as a inevitable gain from the System boon of continuous increase of Chakra Reserves, Host can become compatible with Left Kamui.]
Kakashi's eyes widened in stunned disbelief, he has been a little surprised with everything he has got answers from the System, but the word "compatible with Left Kamui" shocked him even more.
He asked with a slight stammer, "C-can this really be possible, even If I am not Uchiha by blood, and this Mangekyō is not my natural eye?"
[The Sharingan in Host's eye socket, constantly drained Host's Chakra, because Host's body isn't built for Uchiha's Dōjutsu.]
Kakashi nodded and said, "Yeah, yeah, I know that much, but come to the main point..."
[However, increases in Host's Chakra Reserves continuously, which directly results in an increase of Yang and Yin Release Chakra, Host's Chakra network can inevitably overwrite and make it perfect for the Sharingan.]
[Housing vast chakra would inevitably change Host's physical and spiritual state, this makes Host's Chakra pathways and brain's chakra network connect and align with the needs of the Sharingan.]
[Over time, Host's body would effectively evolve to become a natural host for the dōjutsu. Though it wouldn't be instant, but continuous increase in chakra pool, dōjutsu in Host's eye socket will adapt with his chakra pathways.]
Kakashi nodded in understanding, and mumbled, "So, it's basically about overwriting ownership, that makes me, this Sharingan's non-native user, and deeply tied it to me, through my Yin Release, Spiritual energy's growth."
[Affirmation.]
Kakashi raised a brow and asked, "Then... what about Obito, who is the real owner, if the Left Sharingan of his, is overwritten by my vast chakra pathways in future, would he still be the real owner?"
[Negative. Once Host's Sharingan is completely reshaped by his chakra and Spiritual energy, it would no longer be "Obito's eye" but Host's eye.]
[If Obito, re-acquires this Sharingan at that time, the role would be reverted, he will face some problems of a degree of incompatibility. Though being an Uchiha, he still wouldn't have same problems as those non-uchiha's.]
"Hahahaha.." Kakashi started to laugh loudly upon hearing this, but immediately slowed down. "Oh, Naruto is sleeping in next room, I shouldn't laugh loudly, but this, even if it happens or not, but really sounds funny. Obito would no longer be the real owner of his own eye, Hahaha.."
[Host, do you have any more queries?]
Kakashi slowly stopped laughing, and said, "Wait, are you sure that system's only boon is increasing my chakra reserves without limit? These all things, didn't make me believe that vast Chakra reserves alone can have so many benefits!"
