Not bad. Thi is like a proposal for the entire Attack on Titan series. The drawings are a litte rough buuuuut the story is good, a little basic, but it has all the elements of the series, maybe it was like a small side story, and considering how dark is the main series, this one is even a little hopeful.
I like this a lot it is like history for attack on titan season 1
It's sorta fun reading these early drafts for series which end up becoming iconic, seeing some of the budding ideas while they're still not fully fleshed out. A few notable examples of these core ideas:
The art is noticably worse than Attack on Titan (which already isn't the greatest at drawing human faces). At this point, the titans aren't even drawn all that well, but there are some cool action shots. The best-drawn scene is when Murakumo cuts down that one guy. Of course the fights come about because the titans are ravaging the town. The story is built around Tsubaki, who wants to be Murakumo's disciple and train to fight titans in order to get vengeance, and the contrast of such self-serving motives with Murakumo's noble, defense-oriented reasons for fighting.
