Valkyrie Drive: Mermaid

Girls and tits 

Both deal with Yuri leads and have a good amount of risque, sexually suggestive storylines. I enjoyed both for the most part simply because I'm a guy and I love boobs and butts. But I digress, both anime's have a fair amount of comedy and action to keep you glued to your seats..or at least leave you thinking about hentai, lol. 

Valkyrie Drive is very similar to Sin Nanatsu no Taizai, First of all reason it's very ecchi and if you like fanservice both of them will do great for you, Second of all reason for you to watch this is because there might be moments when you think this is cool or funny, after all this show is starting to interest me *coughs* *smiles* fanservice is very interesting if I may say so myself *coughs*. 

Both anime have strong female characters with weapons and constantly engage in hot sexual situations as a prominent aspect to gain powers. These two series are very heavy on both action-fantasy and ecchi genres. If you are looking for that then you will find these two fantastic to watch, there are prolonged instances of battles and lascivious fanservice. 

Super duper fun ecchi lesbian adventures. Not a single superfluous male MC to be seen. Lots of glistening boobs and butts in a fantasy setting. What else can one ask for? Bikini Warriors is high fantasy parody, whereas Valkyrie Drive is sci-fi fantasy that takes itself more seriously than it really should. Who cares about plot though? Boobs. Jiggle jiggle. 

Both are semi-yuri animes with no plot and full of ecchi with only women 

This show is like if "Soul Eater" was made by Studio ARMS,the same people who made Ikkitousen with a chunk of Yuri for good measure. 

Both have characters battling and transforming into weapons. Valkyrie Drive Mermaid is pretty much Soul Eater for an older audience. 

A lot of high quality delicious oppai. A lot of bouncing, touching and sucking of said oppai. Oh, and some action. 

Directed by the great Hiraku Kaneko. Both anime have a very detailed drawing of female n*pples, which was ahead of its time. Both anime tends to focus on yuri-action. Both anime are action packed while having top notch ecchi. Both protagonist has big oppai and a deuteragonist who is smaller than them in terms of height and bust. Both protagonist also wields sword.  

Both shows feature a plot where girls are exiled to a prison island and left to fend for themselves. There's lots of violence in both shows (both of the regular kind and the sexual kind), but Cross Ange is much more bloody and gory, whereas Valkyrie Drive is pretty much softcore hentai 

Both have ecchi parts and weapons based on the personality of the user. 

Did you watch Utena thinking 'This could do with less subtle symbolism, more jiggling breasticles, and maybe some loud moaning'? Did you watch Valkyrie Drive thinking 'I liked the weaponisation of girls by girls, but it could do better in terms of integration with gender criticism and queer theory'? Here lies your solution my friends. Whilst Utena is very gratuitous with its allegories and heavy-handed symbolism, Valkyrie Drive is gratuitous and heavy handed in other, more literal ways. Watch Utena to unsheathe the sword of your heart as you follow the journey of self-discovery of Utena and friends; and watch Valkyrie Drive to unsheathe the sword in your pants as you watch girls 'discover' each other. - Both feature large numbers of not-straight girls. - Both feature the extraction of weapons either from the body or by transformation of the body into said weapon. read more 

Summary of both shows: many boobs and cool fight scenes. If you like one you'll like the other
