If Celene is naturally restless... then even Hill, who is battle-scarred and from a certain background, found Amanata's speaking style to be painfully outdated, clichéd, and verbose.
Even though Hill was watching the captivating plays within plays of Olympia, he would frequently drift into his own thoughts because the buzzing sound was simply too irritating.
He thought that after dealing with the nonsense and ramblings of the Little Fairies, he could withstand any verbal assault... but in front of Amanata, he still ended up defeated.
On the contrary, Celene and Shaer didn't seem to mind it.
Indeed, interacting for tens of thousands of years is completely different from the so-called dozen years of painful torment that Hill went through.
Not to mention Celene, even Lansendel, standing opposite Amanata, looked merely a bit annoyed.
He didn't even open his mouth to stop Amanata... naturally, this might have something to do with him focusing his attention on the Heavenly Mountain.
