From what are You laughing reading this manga... From tortures? From 10 years old trap chained to the wheel and drowned in the pool?
Like bullies laughing from their victim being flushed in toiled with pants down? Nice... Clap... Clap... Clap...
So next time maybe everybody will laughs from rapes, murders, humiliation, pedophiles, wars, tortures, bestiality, scat, crucifixions, public executions... Choose Your subject of fun :) Why not :) Like in Roman Empire: "Bred and Games".
Just understood, that there are subjects, which can not be treating lightly! Because reality is far more worse, then some fiction, and evil is evil, does not matter that it have a sweet cookies! And We live in times, where evil is treated like a "style of living".
I read Uziga, necro (Game of Thrones has it), Wolfsmund, scat, bestiality, and some other weird, fictional or based on reality SHIT!
