Why didn't Sasuke use Amaterasu on Kaguya?


Amaterasu is powerful. Sasuke just had to secretly, when Kaguya was busy with
Naruto, cast it on her. She would have burned to hell.

But why didn't Sasuke use Amaterasu on Kaguya?




Given she be the first to wield chakra,
[Kaguya](http://naruto.wikia.com/wiki/Kaguya_%C5%8Ctsutsuki) can absorb any
technique; including the Amaterasu

> As the first person to ever wield chakra, she can absorb any technique that
> she encounters

However, towards the beginning of Naruto's and Sasuke's battle with Kaguya,
Sasuke _did_ use the Amaterasu on Kaguya to distract her

> To create an opening, Naruto convinced Sasuke to attack Kaguya with
> Amaterasu, which allowed him to get close to her and use his Sexy: Reverse
> Harem Technique. The technique was successful in distracting Kaguya long
> enough for Naruto to strike her
