お兄ちゃん 朝までずっとギュッてして! / Onii-chan Asa made Zutto Gyutte Shite! / Onii-chan Keep Hugging Me Tight Until Morning Comes!

#2. 女未こはく編 / Onami Kohaku Arc

The second anime adaptation of the popular PC game about spending huggy days with cute younger sisters!

The elder brother of the Onami family lives with his four younger sisters, Sora, Akane, Komaku, 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 before going to bed every day.
And they said it would not work unless 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.

Big brother chooses Amber as a hugging partner.
Since Amber is shy about hugging someone who is facing her, her big brother hugs her from behind.
Kohaku is a strong person who can handle all the household chores by herself, but her hug with her big brother brings out the worst in her.
