These series are incredibly similar in their quirky humor, particularly in the way they inject the whole cutesy magical girl stereotype with plenty of gore and brutality. If you like one, you'll surely like the other.
they both short funny and extreme in a simillar way (although DMT is a bit less).
anyway if you liked dokuro chan and like more of that crazy humor (a girl who look innocent that kick ass) you should watch the other (and the other way round of course).
Same type of humor (brutal, physical humor), has beautiful/loli-like women... who can destroy you. Both are good at destroying other people and both parodies the magical girl genre with a ton of violence.
Both animes are fairly similar, both being parodies of the magical girl genre. In both the main characters are fairly similar in personality... Though I would say Magical Witch Punie-Chan has fairly cleaner humor. X3
Besides the obvious similarity -- blonde haired, green-eyed bishes that know how to kick butt when the situation calls for it -- in both these series, cute equals deadly. Random, unearthly occurrences abound and the iconic innocent-to-serious face changes from Excel Saga, if you like pain stirred in with your cute, you can’t go wrong with Dai Mahou Touge.
Both series feautures a gifted girl with a great strenght who looks sweet in the outside, but is awful in the inside, with other people trying to defeat her to obtain her power.
The comedy in both series is also very similar.
If you like Dai Mahou Touge for it's complete lack of respect for the magical girls genre, you'll probably like Puni Puni Poemi; same lack of respect. It shoudl be noted however that this is a spin-off from Excel Saga. And well, Excel Saga. That should be warning enough if you've ever seen it. Or read it. Or know of it at all.
Shows that at first glance star cute girls that do cute things, who actually turn out to be unhinged sociopaths. Expect lots of spastic comedy and rejection of moral standards, and usage of Ride Of The Valkyries?
Both feature characters that normally shouldn't be mean and feisty, so they both have such parody approach. Dai Mahou Touge, evil mahou shoujo and Murder Princess, agressive mercenary girl in princess dress (and tiara).
Both contain two strong female protagonists with a strong bond, are highly skilled for combat fighting (high action), end up fighting against one another, and they're both pretty gory animes. Kagura also closely resembles one of the main female characters in Noir Certain tracks/songs are also similar with the siren-like voices.
Both animes are parodies of anime stereotypes. While Maria+Holic is a play on the sweet boarding school yuri animes, Dai Mahou Touge is a parody on magical girl animes. Both feature a main character who, upon first glance, is a sweet, blonde girl. However, both Punie and Maria are sadistic on the inside. Both shows are comedies and really easy to watch. Dai Mahou Touge is really short (only 8 episodes) and I'd definitely recommend it if you want a good parody of the animes you're used to watching.
