WARNING! This review CONTAINS a small storyline spoiler.
I was more than happy when I first found out that Kira will be aired starting this summer. As I pranced around while imagining the sweet sound of Rena chopping away at someone, I heard a small voice in my head saying something like this: "Glad you're happy mate, but do you remember Rei?
Then my world came crashing down and while I trembled in horror at the thought of another moe-fest, I slowly and carefully began watching the newest installment of the Higurashi series.
I'm gonna be honest. I enjoyed the first episode, but that wasn't Higurashi; and, although Keiichi's hallucinations were extremely....should I say....vivid :D, there wasn't a single speck of storyline in the whole episode. At least Rei tried to have something resembling a story but, so far, Kira is nothing more than a moe-fest, a good and beautiful moe-fest, due to the quality of the animation, but if you're looking for killer lolis I'd suggest rewatching the main series.
The only reason why you should watch this OVA is for pure fanservice and for the sake of completion.
Nonetheless, let's be honest: who wouldn't want a maid Rena feeding you or an all-you-can-eat Mion & Shion buffet? :D I know I would :D
