When side characters singlehandedly ruin a manga for you yikes...
Just tell me that principal elf gets killed off eventually.. she literally makes no fucking sense, she blames Elria for using magic, in fucking self defense, when she could've very well have died there, instead of apologising and taking responsibility it makes no sense, unless she's just a beyond badly written villain, it also doesn't work as over the top "comedy" in response to Elria and Reid being too strong, since she's essentially just telling them to get themselves killed
Story should really just go back to how it initially was about Elria and Reid, because their relationship really was just kinda thrown away for all those annoying sidekicks like dragon girl
