To start off, I haven't read the manga – and as such this anime is extremely confusing for me. I wish they made a series as well, as I feel like they had to cut down everything, given that it is originally from a manga. I assume the manga had clearer story arcs, but in this ova I barely got time to get to know the characters. I assume this is more as an ode to the manga readers, so I'll read the manga and come back to the ova. But if you're like me, it is definitely worth a view, given that it is only 30minslong. I enjoyed it but was left with a million questions, which I hope the manga explains.
