Gray used DeS magic cause he can't use Ice make magic. Freed made magic barrier, remember? DeS magic is specific. That's why Freed's plan ruined.
Where is a problem here?
In addicion to it Gray used only his fists against Freed. Without ice. Same story with Bickslow and Evergreen. He cares about his friends. So yes. I think Gray was galant with Mira
Still waiting for your proof that Gray didn't use it on Mira. What's the reason? To keep powerscaling fantasies about Gray being above her intact?
Face it, the only reason people even claim that he didn't use it is because they can't accept that Gray is as weak as he actually is.
Are you saying he wouldn't have used it on Freed had he needed to if he had access to ice make?
The point of bringing up Freed is to show that he would use it to hurt friends if he has to so the excuse that he went easy on Mira due to that has no canon backing.
Also he already agreed that Mira would resist it as well as Skullion did and said she's be tough, could beat Skullion, he knew he'd fight her heavily injured AND he struggled against her.
You thinking Gray went easy on her is not proof of it. Mira was confirmed to be able to resist DeS and Gray was confirmed to not hesitate to use it on Demon Freed if he needed to do so. He also agreed that he struggled and Juvia said he did his best (to her knowledge). On top of that Natsu wanked Mira as above Gajeel indirectly (along with Laxus and Jellal) all pointing to Mira > Gray with or without DeS.
No where was it ever stated or implied that DeS would put him above her. Gray never said " I can beat her with DeS" instead he agreed that she would be immune to his DeS freezing like Skullion was. Gray never said Mira would be easy to take down since she's a demon. He said that he expected to fight her heavily injured. He never said he went easy against her. Instead he said he struggled because his opponent was Mirajane.
It is clear that Gray is still weaker than her even with DeS and Mashima obviously believes this. Heck Gray himself does too. That's why it's his job to wank Laxus, Erza. Gildarts and Mira in this sequel, because he's inferior to every one of them, even Mirajane.
