Mahou Shoujo ni Akogarete

In akogarete, kinks are what fuel the characters fighting. in twintails, they fight the kinks literally. more connected impossible... (also lots of ecchi) 

Art style and vibe and if someone likes this one.. they will def love Futoku no Guild and vice versa 

You got two groups of natural enemies and when they fight, one enjoys employing sadistic torture methods on the other for comedic purposes. 

Aside from the similar genre's and themes, the MC in both "aid" the villains in various degrees. However, one is borderline hentai while the other is much more subtle.  

Thirsty for more sexed up, so-ecchi-it-might-as-well-be-hentai magical girl parodies? Well, look no further, my perverted friend; this ought to satisfy your cravings.

Both series delve into the darker sides of typically bright and heroic genres, have an engaging story with very lustful and explicit content, and the protagonists' actions are morally ambiguous yet understandable and relatable. 

Both goes about someone getting into a life they don't want to get into and need to learn to live whit it. 

We follow the villains of a classic Japanese Saturday morning kids show being the main focus, deconstruct the hero and meaning of heroism while providing a show not at all suitible for younger audiences. Both are homage-parodies where the studio put lots of care in, showing their love for the genre. 

Both animes are like a +18 parody version of the traditional magical girls shows. 

Two masterpieces with perfectly balanced story, characters, art, music, comedy, SoL and hentai components 

Gushing Over Magical Girls is to Madoka Magica what Madoka is to classic magical girl shows — it's a subversion of a subversion. Though Gushing Over Magical Girls is ecchi (bordering on hentai at points), that doesn't strip of it what it actually is — a dark magical girl show. It has its darker moments and themes and twists, similar to Madoka. There are points in the show where it takes itself and its themes seriously. The mascot characters especially share a lot of personality traits and themes. Additionally, both shows have yuri themes (Gushing Over Magical Girls is more explicit about them than Madoka, but they are both there). Gushing Over Magical Girls is like if Madoka was a way more comedic and perverted ecchi anime. They both have similar themes of downfalls and falls from grace, though Madoka is more of a drama while Gushing Over Magical Girls is typically more comedic about it. Both protagonists are around the same age and start as kind of shy girls.  read more 

Both have the perfect size of ecchi alongside sticking close into their own theme and genre. Both MC start with not having any companion until an unexpected journey take them to place they never thought before. 

A demented, perverted parody of the magical girl genre, the protagonist has the same energy as Excel Saga and the anime delivers almost non-stop tropes, inappropriate and ecchi moments. 

Both are hilarious BDSM anime with many borderline ecchi moments. 

Two incredibly sexual shows with something deeply wrong with anyone who finds themselves a gigantic fan of either (me). Gushing is far more fetishistic, though. Kill la Kill is mostly just skimpy. 

both are mahou shoujo anime with ecchi theme both MC didn't want to become magical girls in the first place mahoako is more explicit 

Both have antihero girls who have to make a choice between satisfying their urges and feelings and respecting the desires and free will of others. Costume designs are similar. Both are dark magical anime with heavy yuri themes.
