I absolutely adore rebellious main characters in yuri.
A lot of series derive drama from having a character who doesn't assert herself, so it's always refreshing when a woman is like this from the get go.
First chapter of “Hirotta no ga Hontoni Neko ka wa Utagawashi” has been translated/scanned
On her way home after being dumped by her boyfriend of seven years, Kaoru Honda picks up a black lump that appears to be a cat. However, its true identity turns out to be a strange creature that speaks human language, enjoys drinking alcohol, and insists he is a cat. Kaoru names him "Modoki" and decides they will live together. As they share a home, her worn-out daily life gradually begins to change.
