A Sister's All You Need. - Tome 10

At long last, Itsuki and the gang are aware of the major identity crisis Chihiro has been facing. Having finally learned the truth, Itsuki seems to gladly accept it-and before long, he’s flirting with Nayuta while doting on Chihiro like a classic big brother.

Meanwhile, Chihiro is about to experience a new story of her own…but is everything as rosy as it seems?
