Shinji had explained everything to Uchiha Hikari in such detail not only to comfort her, but also to tell her how to deal with the Otsutsuki Clan: strategically, they had to look down on their opponent, but tactically, they had to take them seriously. After all, if they encountered an unfamiliar Otsutsuki, no one could say what kind of Dojutsu the other party possessed. One careless move could easily result in them being ambushed by that Dojutsu.
Just like Toneri, who was still imprisoned on the moon.
Hikari thought for a moment, then tilted her head and asked, "Shinji, the Space-Time Dojutsu that Otsutsuki Urashiki used was different from our Space Gate. His Space Gate was not only completely silent, but also astonishingly fast. He escaped because my reaction was half a beat too slow."
"Oh, that was the Space-Time Dojutsu Yomotsu Hirasaka, which could only be used by someone with Kekkei Mōra." Shinji smiled. "This technique isn't an ordinary Space-Time Dojutsu. It's a high-level Space-Time Dojutsu that can be used for surprise attacks on the battlefield. Without any preparation, it would have been impossible for you to stop him from escaping."
Whether it was because he had awakened the Imperial God Palace of the time aspect, Shinji had still failed to awaken Yomotsu Hirasaka of the space aspect after advancing to Kekkei Mōra.
But based on his memories of his previous life, he knew that Yomotsu Hirasaka was an even more difficult Space-Time Dojutsu to guard against than Kamui. The user could even remain rooted to the spot while transmitting his fist through Yomotsu Hirasaka to appear behind his enemy.
If it had been the Fourth Hokage or Itachi, geniuses with fully maxed-out combat talent, using Yomotsu Hirasaka instead of Urashiki, Hikari would definitely have suffered a major loss
