Yeah, it was the first time. It doesn't matter to me if the cosplay is "bad". Most people I saw were doing more low bdget cosplays, and they still looked amazing to me.
LNs and mangas there were sold for an extremely cheap price, to give an example: I bought all of the 4 novels of the sword oratoria series for just 15 euros. I also bought all of the Appleseed manga and appleseed XIII for just 10 euros.
The nearest library where I could buy them is about a 2 hour car drive away.
