>>1040400Looks more like Ohana slipped and fell down. The Megami poster is more yuri compared.
The manga does seem to tone down the hostility Minko has toward Ohana. For instance, Minko is the first to sit down and eat Ohana's meal (she still storms off in the end) but also Ohana is shown to be more or a ditz in the manga.
YMMV.
