Hey guys.

I've read the first volume and a half. I like this. But b4 I move on i noticed tht it started as most good series do.... From being based on a novel series... While also having an anime adaptation...
Can anyone mind telling me how much does the manga series resemble the novel.... If at all
And if the anime resembles either
And if the novel and or anime are better or worse and maybe even worth reading/watching
