While Aiura is fairly charming and has a catchy OP, it simply fails to deliver anything of substance. The OP and ED consume one minute each and the total length of each episode - including those - is four minutes. The humor often falls flat, the characters are amusing but left woefully undeveloped.
I really feel like someone is being betrayed by this anime. It may be that the writers were betrayed by a studio that simply refuses to put in effort. It may be that the producers were betrayed by investors and can't afford to make an actual show.
The real problem - and the reason I'm dropping Aiura after episode 3 - is that I really think that the one being betrayed here is the viewer. No show should spend 50% of its time on OP/ED and consider itself worthy of being aired. Aiura may have made the cut and been a mediocre slice-of-life if it had full-length episodes, but as it is it's simply a shameful black mark on reputation of the industry at large.
