#3. 女未あかね編 / Onami Akane Hen / Onami Akane Arc

The third anime adaptation of the popular PC game in which you spend your days hugging cute little sisters!

The elder brother of the Onami family lives with his four younger sisters, Sora, Akane, Koaku, and Sumi.
He has a daily routine of “sleeping with one of his sisters” since he suffered from severe asthma when he was little.
One day, her parents, who are also researchers, ordered her to conduct a demonstration experiment on how hugging improves immunity.
The order was to “hug your sister lovingly for at least 10 seconds every day before going to bed.
And they said it would only be effective if several conditions were met.
The younger sisters, despite their brother’s confusion, displayed the conditions in a frame in their living room as the Five Rules of Hugs for Women and Children.
Hug your sister every day.
Hug for more than 10 seconds.
Smell your sister properly.
If you get separated, start over.
Hug her with love.
Akane is chosen as the hugging partner.
Akane’s hug with her arms and hands around his neck makes Akane’s feminine body throb with excitement, but she tries her best to keep him from realizing that she is his younger sister.
One day, when he returned to his room after taking a bath, he found Akane, who was in charge of sleeping with him, having sex by herself.
