" Hey , hey ... that 's some good shit ! " " It 's sake ? " Rin gripped the mane of Anotsu 's horse when it turned to touch noses with the other ; she still felt unstable on a horse by herself , especially since she had chosen to ride sidesaddle . " Nope , shochu . " Manji tilted his head back and took a long , stiff pull , his throat bobbing . He squinted against the sun , wiped his mouth on the back of his hand and let out a heated puff of breath . " Hahh !
