Kazuki felt that he might now be on par with Hagoromo back then, but not Hagoromo in his strongest state, rather Hagoromo when he fought Kaguya.
As for how strong Hagoromo is now, Kazuki didn't know. He suspected that the current Hagoromo might be even stronger than he was in his Ten-Tails Jinchuriki state back then.
When facing Kaguya, who had broken free from her seal, he didn't even need to personally intervene. He only needed to help Sasuke and Naruto activate the Asura Chakra and Indra Chakra within them, and then transfer a portion of his Six Paths Yin-Yang Chakra to them.
Of course, it's also highly possible that Hagoromo was helping from behind the scenes when Obito lent his power to Kakashi. Compared to Kaguya, Hagoromo seems more like the true mastermind.
Hagoromo shared the seeds of Chakra with the people of the Ninja World, allowing everyone to gain access to power. After their deaths, their souls would go to the Pure Land. Kazuki doesn't know what the Pure Land is or if Hagoromo is planning something there. He needs to continue exploring this world to find out.
Fortunately, with the combat arena, whether it's the Sage of Six Paths or Kaguya, he believed it was only a matter of time before he would catch up to them. After all, at the end of the day, he's still just a twelve-year-old boy. He still has a long time to grow.
Afterward, Kazuki easily dealt with Obito. While Kamui is indeed tricky, it couldn't stand against Kazuki's cheating, directly using Limbo: Border Jail to ambush him.
What's more, Kazuki himself possesses Yomotsu Hirasaka. As long as he wants to, he can enter the Kamui dimension at any time through Yomotsu Hirasaka and forcibly kill Obito.
Some things that are very troublesome for ordinary ninjas are not out of the box to the Ōtsutsuki clan. Only when one's strength reaches a certain level will they realize how ridiculous some ideas are.
For example, at first, Kazuki considered using Wood Release: Advent of a World of Flowering Trees against the Ōtsutsuki. Wood Release: Advent of a World of Flowering Trees has special pollen. Once inhaled, even Kage-level ninjas will pass out from paralysis.
Even Madara experienced a dazed state after inhaling the pollen. However, this Madara hadn't awakened the Rinnegan. If this poisonous powder truly worked on genuine powerhouses, Hashirama wouldn't have refrained from using it on Madara.
In reality, while Wood Release: Advent of a World of Flowering Trees is powerful, if the life form exceeds a certain level, Wood Release: Advent of a World of Flowering Trees becomes ineffective.
If it could truly affect the Ōtsutsuki, Kazuki would be laughing in his dreams.
[Ding, congratulations for defeating Masked Obito, you have obtained Kamui. Do you wish to merge it?]
Although the current Kamui is now dispensable for Kazuki, it's better than nothing.
At least he now has a Mangekyo Sharingan ocular jutsu, right?
Being unable to evolve his three-tomoe Sharingan into a Mangekyo Sharingan left him feeling a bit helpless, as he had two fewer ocular jutsu.
Fortunately, he has the combat arena. Not only does he possess Amaterasu, but also Obito's Kamui. He will most likely acquire more Mangekyo ocular jutsu in the future.
Unfortunately, this is only the Kamui from Obito's Mangekyo Sharingan, he still needs the Kamui from Kakashi.
After merging Kamui, Kazuki, with renewed vigor, challenged Kakashi.
This time, Kakashi made Kazuki expend some unusual effort. What surprised Kazuki was that, perhaps due to the influence of Ten-Tails Chakra, his previously infallible Limbo: Border Jail was actually detected by Kakashi, which made him expend a considerable amount of effort.
When dealing with Kakashi, who possessed dual Mangekyo Sharingan, Kazuki needed to be careful of Kamui's power. Fortunately, he himself already had Kamui. So he didn't need to worry about Kakashi.
However, Kakashi had some tricks up his sleeve. After expending some effort, Kazuki defeated Kakashi.
[Ding, congratulations for defeating the Dual Kamui Mangekyo Sharingan Kakashi, you have obtained Kamui. Do you wish to merge it?]
Has he gathered all of Kamui?
Kazuki wasn't surprised by this.
Only by gathering both Mangekyo Sharingan can one unleash the full power of the Mangekyo Sharingan. This refers not only to Susanoo but also the synergy between the two Mangekyo Sharingan.
Aside from Itachi's two Mangekyo Sharingan abilities not being particularly synergistic, the ocular jutsu of others, such as Sasuke, Obito, and Shisui's Mangekyo Sharingan, are quite compatible.
Another month of significant power increase.
Kazuki hoped that next month, there would be a few more Jinchuriki.

"Recently, Kazuki seems to have been very low-key." Ryoma called Fugaku to his presence.
"Yes, father, I don't know what he's doing. I heard Hokage-sama is training him, seemingly teaching him things a Hokage should learn."
When mentioning this, Fugaku's eyes were filled with complex emotions.
Kazuki's current treatment was everything he had ever dreamed of. Even as an Uchiha, Fugaku yearned to become Hokage.
He had also thought about becoming the first Hokage from the Uchiha clan. But he hadn't expected someone like Kazuki to emerge out of nowhere. He was considered a genius by everyone, yet Kazuki proved to be even more outstanding than himself.
He had awakened the Mangekyo Sharingan, the legendary eyes of the clan, but Kazuki awakened them even earlier than him.
Kazuki could even use Susanoo on a scale he couldn't even imagine. Fugaku suspected there was something wrong with Kazuki's eyes, but then he thought it over and realized it didn't make sense.
If there truly was something wrong with Kazuki's eyes, he wouldn't be using his Mangekyo Sharingan so unrestrainedly.
