Typical to shounen anime, Dog Days is what you would you call an anime in which you just sit down and enjoy the fan service it provides.
In the land of Fronaldo, the Republic of Biscotti has been aggressively attacked by the Lion Kingdom of Galette. Facing potential defeat, Princess Millhiore summons a hero who can save the country. What she gets is Izumi Shinku, a middle-school boy from Japan. Awaiting him in Fronaldo is the task of becoming hero enough to defeat his enemies while learning the peculiar rules of battle in this strange new world.
The way that this anime is presented is definitely targeted at a young teen audience. This is pretty evident at the simplistic yet engaging story that it offers, simple understandable and straightforward character representations and the use of fantasy elements that seem to be the answer to everything. Of course, you can't take anything seriously in this anime as most of it is pretty much cliche dialogue designed to appeal to younger teens and it does that so well with a simple yet captivating storyline. Who doesn't like a story about a boy that gets summoned to a different world and is instantly crowned the "hero"? You can pretty much guess the story from here on. Note that the story also comprises of two countries at "war" (well, more like a competition game mock battle thing) with each other. To make it family friendly but appealing to younger teens, there is very little blood but heavy action. Also, the soldiers in the anime don't actually "die", rather they turn into "orbs" which will last a couple of hours. So, treat this as more like a game than an actual war.
The animation was beautiful, the vibrant colors really added to the happy and cheerful mood that the series had initially. Also during battles the visual effects used to animate the magic are visually appealing too. The fights themselves are well done too. The characters looked appealing and very cute. It is not often you see anime featuring dog people and cat people.
The voice acting was not too bad. I noted that some character's voice acting in some scenes felt a bit hit ans miss. However though, I instantly recognized some popular voice actors from other anime featured in Dog Days, so that was a pleasant experience. The theme songs were pretty standard action-type music. Nothing really catchy to me, but it was lively and suited the anime nevertheless.
Izumi Shinku is portrayed as a flawless hero in this anime. By the way he is presented, you can instantly tell this is definitely for younger teens. Izumi is basically one awesome overpowered guy that just seems to be good at fighting with a staff. Even right after he is summoned to the world, he joins in the battle and saves the day. So you think that he is pretty OP already, and he is to. The anime doesn't really explain how he got all his skills from, but there are some hints that are there to guide you. Princess Millhiore is quite ordinary and not really too quiet or energetic. If I would to describe her, I would say "plain and simple". She is cute though and she does show her feelings for Izumi at the end of the anime.
Overall, I quite enjoyed the fan service that this anime provided. Of course though, it isn't all about the fan service, but also the way that the anime is presented. Simple and easy to get into. Older teens might not like the way the story is presented but the younger generation will definitely like it.
