Kabaneri of the Iron Fortress (TV)

[KrayZ33]

I was more or less refering to their mindless stalking.
Mikasa doesn't think on her own, she does what Eren wants and she'll do what's necessary to both follow and protect Eren.
Mumei is a drone too. Though she changed sides somewhere in between just to be talked into someone who has absolutely no trust in herself by someone who, how we found out later, was considered a traitor/or unworthy of Biba (that was os stupid). I'm not even sure anymore how it all happened, she was afraid of being thrown away or something... which is also somewhat similiar to how Mikasa acted when she thought Eren dead. No longer were they calm and calculating etc.
