Yuri

The older of the twin sisters.

She had been blind since birth, and because of that, there were times when she envied her younger sister, Arisu.

Since Arisu had cared for her in place of their parents, Yuri feels deeply indebted to her sister.

Because of her condition, she was somewhat detached from ordinary society, but after her eyesight was restored, she became much more sociable.

As for Arisu's excessive affection toward her, Yuri accepts it with an attitude of, "Well, I guess it can't be helped."

However, she has also come to enjoy aspects of it that go far beyond what could reasonably be dismissed with "it can't be helped."

She is able to transform her body to a "futanari" as well, though unlike Alice, she cannot produce tentacles.

Unfortunately, she is perfectly suited to serve as the vessel for ■■■■, making her a one-of-a-kind existence in the universe—someone for whom there is no replacement.
