Nearly everyone in the show is mischaracterized. Mori, hes a well written character. Hes a villain. Hes meant to be unlikeable and hes smart. Hes one of the smartest characters in bsd. Its annoying that all he gets watered down to is a pedo. Hes an interesting character and although i dont support his actions, i find him likeable in the show.
Dazai. He is NOT a hot alpha suicidal baddy wolf demon hybrid bad boy. Nor is he a wet skrunkly innocent feminine cat or whatever. Hes a 22 year old suicidal man that has intense trauma from the abuse he had to go through as a teenager. He was an abuser, and he was abused. He has killed people before. A lot of people water him down. Dazai haters hate him because hes bad. Hes morally grey. Nearly every character in bsd is morally grey. They only hate him because hes annoying (which is basically a coping mechanism) or because he abused akutagawa. But then they love akutagawa even though he abused Kyouka??? Double standards much. Its annoying seeing how mischaracterized he is.
Chuuya. Chuuya isnt a feminine tsundere uwu cat boy or a violent and aggressive person. Hes normal. Hes loud yea and sure he can be aggressive but thats because he grew up on the streets and is literally in the port MAFIA. He has manners and is shown to be kind at times. Also hes not a tsundere. As much as i like soukoku its really annoying seeing people water chuuya down to a tsundere or smth like that. People need to stop feminizing him. He doesnt hate dazai. Its canon. Their relationship is complicated and hard to explain. But he definitely is NOT a tsundere.
I would go on to ramble more and more about everyone but this is already really long and i had to cut out a lot but basically people need to stop reading/watching with their eyes closed and actually look at the show/manga. Because these characters are well written and complex. The show is about black and whites. How not everyone is good but that doesnt mean theyre evil either. Its stupid trying to make those MORALLY GREY characters fit into either a black or white box.
