Arata Shiunji is the main protagonist of The Shiunji Family Children series. He is one of the third oldest Shiunji siblings, along with his "twin sister" Oka Shiunji and he is a second-year high school student.

Arata has short, slightly spiked, dark brown hair and the bottom half of the back of his head is shaved. He is the tallest of the Shiunji siblings, and has a strong build from working out. His eyes are narrow, emphasized by his thick eyebrows that are almost always slated downwards.

Arata is very protective of his family and caring to his siblings, perhaps in part due to the burden he feels from being the eldest male son and the heir to the Shiunji fortune. Despite his rather sharp and almost aggressive looking facial features, he gets flustered very easily. Arata is shown to carefully think out his words and actions, though his intentions are frequently misunderstood. He usually turns towards his brother Shion for advice, even though he's younger than him. Each time one of his sisters comes after him in a sexual or romantic manner, whether jokingly or seriously, he is very quick to turn them down and reiterate that they are all siblings regardless of blood relation.

On top of the situation with his family, he's also been struggling with one-sided feelings as the girl he has a crush on, Rara Yakoyama, already has a boyfriend. Scared to make a move beforehand, he now has no idea whether or not it would still be a good idea to approach her. It's unknown if Rara even knows he exists, as he always hides when he sees her and is too scared to even send her a friend request.
