Samee I like that this isnt romance too hahaha got tired of those. But I bet it was easier for Cale cause the title "trash" that's always attached to him makes it easier for him to do what he wants and he isnt the type that goes omg I die if I continue to be a jerk so I must change and become a saint. He still stuck to what he really want to be but just avoided the situations that would lead him to get beat up or die.
I want a manga where the person transmigrates and is like "fuck no, not doing. A harem" and like he saves a slave and the slaves like "Master" and he immediately gets rid of her at first opportunity, meets a tsundere girl and he shuts her down before she finishes speaking and makes an effort to never see her again, loli shows up and this NOT pervert o's like wtf where r Ur parents? And drops with a couple he knows who always wanted a kid, and so on
Fuck big boobed harems

If Cale were a female character, he as a she would unintentionally made many dumb male characters fall in love with him and evil jealous bitches would be just keep targeting him... I also praise Cale for not creating his own harem with big boobs "accidently".
The only female isekai character so far I know of who doesn't have to deal or accept the cliche bullshit is Melissa + Yona from "Beware of the Villainess".
Correct me, if I am wrong but Melissa and Cale are probably the only MC characters in their genre who realy like to keep a low profile and doesn't give a damn about popularity, reputation, societal norms or the opinions of others.
Many transmigrators or isekai heroes say that they don't care what others think of them and do whatever they want. But at the end they still care about their image, fantasy rules for whatever plot reasons...
I am all ears, if you can name me protagonists who are not bound by their image, etiquettes or mannerism based on a conservative classist society.
Maybe "Potion Tanomi de Ikinobimasu!" and
"The Monster Duchess and Contract Princess"
