At St. Mihailov Academy, strange things are happening. Not only did the dean disappear, leaving his daughter Tomo and adopted daughter Mafuyu alone, but girls in the nearby city are being killed by an unknown foe. However, the blades begin to fly when a Russian boy named Sasha arrives. He is a Qwaser, a person able to manipulate the elements after ingesting Soma, breast milk, and he’s not the only one. Soon Tomo and Mafuyu find themselves in the middle of a battle between two groups of Qwasers whose goal is to protect or steal the Theotokos of Tsarytsin. With more allies and enemies arriving, who will survive the assault?
Titties. Both have titties, both have massive amount of titties and both put woman's rights and equality back about 20 years. Excessive fanservice over plots, more detail in the titties and acts around titties than in the characters themselves, a budget geared towards animation and milk. Loads of milk. And while Seikon no Qwaser tries to have a plot, it largely doesn't matter and is just a means to show titties on screen. And it has action, something that Kagaku na Yatsura has in some degree, mostly of the sexual kind. Chances are if you can get through one, you can get through the other.
Loads of breasts, breast milk spurting out at every opportunity, a complete disregard for women and some truly appalling characters - The both have each of these not so desireable traits by the bucket.
Seikon no Qwaser has a plot, and falls flat on its tits in doing so, at least Kagaku na Yatsura did without and got straight to the action, so to speak. Nobody should ever watch either of these abominations, but if for some reason you're into this kind of thing, i think you'll enjoy each of these.
Both are faithful to their source material, which are similiar in the case of there being a single dude surrounded by extemely chesty broads who are stacked with breasts ontop of their extreme cleavage. With tits. Actually, both of these are about tits. The plot is largely irrelevant, the characters pretty titty or there for borderline sexual harassment shennanegans while being flat, the animation is 90% of the budget and it's truly, seriously, all tits and ass. There are some shots that deal with the rear end and crotch because you have to cover all slappables. Pervs only because the animated back breakers are all they have going for them.
Honestly they're pretty much based around the same concept: crazy amounts of fan service, which isn't necessarily a bad thing because they don't try to act like they're focused on story. Instead they just sort of sprinkle some in just as a supplement to make the whole thing flow better. All in all both shows are pretty easygoing and if you like one I know you'll like the other.
Aaaah, the good old ecchi, bordering on hentai anime that straddle the line between disgusting and illegal, 'tis indeed a most dark corner of the anime world.
If you enjoy tits of all kinds, naked loli's, that weird hand-clapping sound that's meant to be breasts jiggling, rape, animated orgasms, girls wearing shamefully revealing attire in public, loads of groaning and moaning and the crowd pleasing incest then you should be ashamed of yourself. But luckily these two OVA's should please the fluids right out of you.
I actually had a hard time deciding which one is the tamer of the two. Rescue Me! features cumshots, child-bearing incestual fantasies and male-female sex scenes. Even if the sex scenes are censored it doesn't detract from the fact they exist. It's also fairly heavy on the harem factor.
Kagaku na Yatsura on the other hand throws hardcore incest our way, and the pukeworthy staple of the hentai genre, tentacle rape. Plenty of milk shooting out from certain parts of the female anatomy as well, just for good measure.
So i guess the more hardcore would be Yatsura, but chances are a fan of one will enjoy the other. Now excuse me while i'm off to take a shower to wash away the shame these OVA's brought me.
Yup, both are about breasts and not much else. Other aspects are butts, sexual harassment, sexual deviancy, rampant fanservice, non-plots and more mammaries than you can jiggle at. Qwaser attempts a plot and fails, Kagaku attempts at plot and ends up with drugs and tentacles and both are quite simply marvels at what animation can do to further put physics and biology behind in the animation jiggle industry. Come for the boobs, stay for the giant boobs because that's all you're getting from either one.
