All the water or like the element effects( I dont know what to call them sorry) have been confirmed to be solely for looks and dont actually look like that, but Zoro has haki which can break any sword, and observation haki so yeah. Although I do think maybe demons have a chance if its night time because demons can only die to the sun or nichirin blades
It depends that who you are and what your experiencing.For me,my older brother is a topper kind of child and everyone in the family keeps praising him and always taunts me for not studing as hard as him and not scoring as good as him so everyone treats me like dogshit in my family and no matter what I do I don't even get recognised.The internet shi about the youngest siblings is quite the opposite for me,now that he's kind of a grown now,he sometimes,in anger,says mean stuff to our parents and you know my parents reaction?they come to "me" and say that I'll leave them once I'm an adult even thought I didn't said anything and also when it's my mistake it's completely my mistake,but when it's his mistake then also it's completely my mistake,for eg. When I was in 1st class and he was in 5th,he forgot to do his SST HW so he got a lil scolding but for me,(even thought I didn't do anything) my father asked me write the answer of the divisions that the wrote in the copy,Since was in the first month of me being a 1st standard child I didn't knew any of that,so,you know what he did? He literally kicked me out of the house (even though my mother called me back 1 minute after) but still that dosent change the fact that he did kicked me out even thought it wasn't my mistake.You don't know about anyone's life by just knowing who they are it might be the case with some the younger siblings but it's not the same for everyone bro it's not the same as everyone.
