Sorry, the characters in this manga are too dumb for me. Especially the knight.
I don't think it's offensive, nor am I offended by any means, since I don't think the author meant anything bad with it, or had any deeper meaning with it, just wanted to create some gags. Him being little of a nuisance at the start was fine, and I could laugh with the jokes..
But then the knights homosexuality made him waaaay too f*cking ret*rded....
I have in mind though that he the cursed 'changed' not just his sexuality, but is whole personality. Thus I could tolerate him being annoying as long the other characters was well written...
What actually made me drop this was when Chroma decided to try to lift the curse on Hime.... Plot relying that all the characters being way too dumb, isn't my cup of tea.
The knight's curse made him waaaay too ret*rded and made him too much of a liability, and Hime's curse seem to depend largely on the knight 'not loving her anymore'... They even seem to acknowledged it in the manga! She calmed down for a sec! Lift the knight's and you essentially solve the two BIGGEST issues in essentially one go...
But no, the "plot" needs to go on...
