~Story~
First of all the comedy is based on the manzai, where a "Tsukommi" (straight man) retorts the actions of the "Boke" (funny man) who creates a funny situation. This is quite frequent in japanese comedy shows, and being a personal fan of this type of comedy, naturally appealed to me. However, if this type of comedy doesn't appeal to you, then this may be not suitable for you.
D-frag focuses on the delinquent Kazama Kenji, who with the help of his gang, the "Kazama" gang, intends to take over his school. This doesn't go as intended and in the process he is forced to join the game creator club (temp), composed of the most strange girls. From here on audiences observe how Kazama deals with the bizarre club members, leading to absurd and hilarious situations. These range from typical everyday life situations, to the same events a lot school comedies have to offer, such as territorial fights or festival games, naturally taken to the extreme absurdness.
D-frag has little story to offer, besides the actions of the game creator club (temp). The story is split in mini arcs, each with enough comedy to make you laugh, making it perfect for this type of anime. It also tagged with the romance and harem category, though the harem aspect is not the main focus of this show, neither is the romance. Moreover, it is used to enhance the comedy.
~Characters~
Being a comedy based anime, D-frag has a lot of characters to offer, each with its own charm. As it is a harem too, there are a lot of female characters but these are not detrimental to the anime; which is to say, it doesn't exhibit an excessive focus on the females. Personally speaking, the protagonist Kazama was of the most interesting character as it was not your typical main protagonist. He doesn't take romantic interest in the female lead characters, neither does he always accomplish his goals, in fact he is often helped by someone, which is bonus.
Other character that stood out, and is my personal favourite, was the teacher Sean Conne Conne, who clearly represents the actor Sean Connery. His character, moral values and actions are very refreshing to the anime, besides enhancing significantly the awe factor of this character. Naturally, character development is nihil in this anime, in addition to the fleshing out of the characters.
The secondary characters also play an import role D-frag: these have all certain personalities that makes it easy to distinguish from the others. While the protagonists create absurd and hilarious situations, these are often enhanced and supported by the actions and comments/retorts of the secondary characters, and vice versa. There are also different factions present, each with their characteristic attribute, for example, the baldies or music bands. The good thing is that these are all simple and not such impressive characters, they're in fact simple people even though the anime portrays them as "badass" characters.
~Animation and sound~
The animation quality of D-Frag is nothing outstanding, though well executed, what is to be expected from a modern show. The art style of D-frag was toned down a bit from the manga, which was at first rather lackluster, and is a welcoming change. Character designs are varied, yet are nothing remarkable. The facial expressions were well done, which was of importance for the comedy gags, as without them it would have been worse.
The soundtrack used in D-Frag was nothing outstanding and it could get repetitive at times, yet there were some compositions that fared well with the different sketches and situations it was trying to portray to the audience. The voice actors performed their roles well, fitting with their character's personalities, as in addition enhancing the comedic element of the anime.
~Enjoyment~
I personally enjoyed D-frag a lot; It made me laugh throughout the whole duration with hilarious and absurd situations, as well as the wide assortment of characters. There were naturally some gags that got old or were predictable, besides of having no story direction whatsoever: this was nevertheless a small drawback. So if you are interested in watching a comedy anime with an enjoyable harem, or just are searching for something to watch, D-frag may be something for you. Just don't expect any deep characters or story.
Thank you for reading.
