Story
The big brother of the Onami household lives together with his four little sisters: Sora, Akane, Kohaku, and Sumi. Because he suffered from severe asthma as a small child, 'sleeping together with one of his sisters' has become a daily routine. Then one day, his parents, who are also researchers, order him to conduct a demonstration experiment on 'immunity improvement through hugging.' Big brother is flustered, but tries hugging Sora as practice. As Sora gently rests her weight against him, the softness and warmth of her body come through, and big brother's heart races more than he'd expected.
