I have to say, it's been a long f*cking time since I read an Akame ga Kill! that I actually liked.
Hopefully, Tyrant can't go back to being Tatsumi.
Yes, Esdeath's "winter is coming" power seems like it is a total asspull, but it is not that OP when you think about it for a bit. Yeah, it kind of freezes a wide area, but it only really enables her to use her powers without exhausting her. It still does not beat the OPness of Pumpkin.
I am really looking forward to the ending of the manga now, which might just save it from being a bad manga and land it on "average" or even "good" territory.
If the author was bolder than he actually is, then one could hope that Esdeath actually won because she is the strongest character in the manga and definitely should win, by right of might.
