I really hate these types of enemies.
So fucking overdone bad guy. It just makes me feel really shit. no really, it does.
Some other manga also had VERY similar set up and villains who were also EXACTLY like this. Fucking overdone bad guys who would terrorise kids and fucking reanimate corpses to kill people.
Another thing I hate?
People with fucking ridiculous powers. Even worse, powers that aren't even explained until they are used.
Even worse! Powers that seem to have been completely unused in the 20 years before this happened and the dudes already had such power. I mean it looks like the only useful dude the oni side has is the instructor. How the fuck have they not been wiped out already?!
ugh...
