Moving on.
<Akame fought Mera who defeated her mentor when he had Murasame, she didn't even need it to beat Mera, by the way Gouzuki is the most well known Assasin in the empire and was renknowned for being the original demon of the sword. Mera was also the best assasin by the Rebal army at the time of her defeat. Able to take on imperial arms users and win despite not even using one herself.
<Akame herself is capable of intercepting and Identifying two assasins ambushing her from a mere glance and managed to kill one on her literal first strike but striking at the grip of the weapon where it was being wielded.
"stand against aizen"
Do not use Sui-Feng standing against Aizen as a feat, that's just wank and that ENTIRE fight was the group of people being fooled by his KS.
Getting toyed with by Aizen just like everyone in that fight is in no way shape or form a feat. If I went by that logic I can say Akame was comparable to Esdeath as she took a stand against the rest of the Jaegers.

Two of her most notable fights, without Murasame by the way.
