Only 18 years and 0 months old at the time of filming! Born in 2007, the overwhelmingly youngest girl, Yui Yuki, finally reveals herself! With her delicate skin, fluffy white cheeks, shy way of speaking, and innocent, childlike smile while playing with soap bubbles... her purity is the very definition of "freshness"! Once the shoot begins, Yui-chan is bewildered and bashful as she strikes bold poses in a tiny swimsuit. The sight of her immature, forbidden fruit at exactly 18 years and 0 months, which she couldn't quite hide, brings an unstoppable sense of immorality and excitement! She possesses the fresh radiance of someone who has "just turned 18," with a petite, slender body still in the process of growing. This is a precious, permanent-collection work packed with the most youthful sparkle imaginable in this day and age.
