Koroshiya-san: The Hired Gun is one of the strangest examples of an anime I've seen in a few years. Normally, the strange appeals to me, but in this case, it's simply dreadful. Koroshiya is an adaption of a 4-koma manga of the same name, but when it comes down to it, this form of anime is not suited to adapting a four panel manga. In all honesty, I'm sure the creators of this anime don't take this show that seriously. Each episode is three minutes long, and a minute of that is dedicated to the opening, which is one of the worst animated openings I've everseen. Apparently,this show is supposed to be a comedy, but in the end, all I find myself laughing at is the absolute pointlessness of it all.

I don't even think it's fair for me to go on about the art or sound. It's bottom tier (maybe even below that) quality, and the voice acting is stilted, and boring, and the dialogue is pathetically devoid of humor.

The characters are the highlight of this 'anime'. That is not a compliment. Koroshiya seems to be some sort of screwed up hybrid of Gintoki Sakata from Gintama and Agent 47 from the Hitman series. Any other character are completely and utterly pointless.

I sincerly hope that this anime was not made with any serious intent, because this is arguably one of the worst anime I've seen in a very long time. It's entirely likely that the original 4-koma manga is very funny, but the main issue with this piece of crap is that it's style does not translate to the screen. At all. Ever.
