Both shows take historical male characters and turn them into busty kick ass ladies. Very entertaining and not to be taken seriously at all. Battle Girls are in their own land and get a normal human transported to their world where Sengoku Collection takes these historical figures and transportes them into our time! Check em out.
Ryofu Housen (Lu Bu) is a powerful general from the Three Kingdoms. Alongside Chinkyuu (Chen Gong), Ryofu suddenly finds himself falling to Earth, and landing... in the body of an elementary school student?! With their new lives as flat-chested, women-loving children, Ryofu and Chinkyuu follow their hunger and their desire to get back to their old lives somehow; but it will be difficult, given the variety of obstacles in their way including old enemies, epic monster battles and the most important thing of all, trying to get their hands on Eri-sensei's mammoth F-cup breasts!
Do you like it when historical figures get transported into our time and turn into cute girls? Look no further than these two anime! Ryofuko-chan takes Romance of the Three Kingdom characters where Sengoku Collection takes from Oda Nobunaga and friends both will surely make you giggle if you are into this kind of thing.
Both shows feature female versions of sengoku period generals, oda nobuna is a reversed version of sengoku collection in oda nobuna a person from current time japan is transported to the sengoku period and in sengoku collection the generals are transported to modern day japan. Another difference is that sengoku switches characters every episode whilst oda nobuna has an actual plot. Though if you liked one you'l most likely like the other as well.
