本作の主演は夏目響ちゃん！！声は愛らしく、人柄も良く、生き様までも綺麗な清潔感あふれる美女だ！！前作より約2年、トレードマークだった短髪を伸ばし、ロングヘア姿を初披露。本作のヘアスタイルの多くは、響ちゃん自身のセルフプロデュースである。『Echoes of floret』から始まった彼女とREbeccaの歴史は、まだ小さな新芽の頃からともに歩み続け、ついに大輪の花を咲かせる。2026年8月をもってV女優としての卒業を宣言。6年に及ぶキャリアの中で、一日を通してイメージ作品だけの撮影を行うのは本作が最初で最後となる。響ちゃんのお気に入りは、約8年ぶりという縄跳びのシーン。「クーパー靭帯の大活躍物語を楽しんでもらえるかな？」と悪戯っぽく微笑む。ヘルペス監督による全裸おっぱいインタビューでは、撮影の感想や最近ハマっていることなどを、身振り手振りを交えながら真摯に語ってくれた。「『名前はまだない。』という存在でデビューしたから、引退理由も謎のままの方が一貫性があって綺麗に終えられるかな」と卒業への胸の内を明かす。名前のなかった彼女は永遠の女神へ。光の中に残されたのは、言葉を超えた美しい残響…
The star of this film is Natsume Hibiki! She has a lovely voice, a great personality, and is a beautiful woman with a clean and pure image, even in her way of life! Approximately two years have passed since the previous film, and she has grown out her trademark short hair, making her first appearance with long hair. Many of the hairstyles in this film are self-produced by Hibiki herself. Her history with REbecca, which began with "Echoes of floret," has continued together since they were still tiny sprouts, and has finally blossomed into a magnificent flower. She has announced her retirement as a V-actress in August 2026. In her six-year career, this film will be the first and last time she shoots an image-only film for an entire day. Hibiki's favorite scene is the jump rope scene, which she is doing for the first time in about eight years. "I wonder if you will enjoy the story of the Cooper's ligaments' great performance?" she says with a mischievous smile. In a full-nude breast interview with director Hes, she sincerely talks about her impressions of the shoot and what she's been into lately, using gestures and body language. "I debuted as someone who 'didn't yet have a name,' so I thought it would be more consistent and a cleaner ending if the reason for my retirement remained a mystery," she revealed, expressing her feelings about graduating. The nameless girl has become an eternal goddess. What remains in the light is a beautiful echo that transcends words…
