Kagaku na Yatsura

Idek myself. Someone kind of just wanted money and came up with ridiculous upon ridiculous situations stacked atop of one another just because ecchi is silly. I suppose it is more loveable for that reason if open-minded. Would recommend it if you are looking for nothing but fanservice. Although Kagaku is heavier with that than Asa Chu's cuteness calculated into its equation of an anime. Both are uncensored too, yes.  

- Same director - Same animation studio - Extremely ecchi shows which go so overboard that they can basically classify as hentai - Great focus on big fat voluptuous round anime tiddies 

From the beginning, we question, we question with no end in sight. Sometimes we satisfy our curiosity, other times we wish for more. I want to know why these two anime exist in a very serious sense because it is just borderline hentai for the apparent sake of "lmao". They aren't long so there is no harm in watching them, but they are two strong ecchi that will make you question even your own roots of Yggdrasil. Both are uncensored too, yes.  

Both are ecchi OVA (and when I say ecchi I mean most of the screen time is a fanservice). The main hero is surrounded by girls moostly with really, really big chest. And of course they are in love with him.
