Inui Rikka is the new S1 hottie who debuted last month in SSNI-387, a very decent debut. With 170cm tall, she is effectively the tallest girl in their studio too.
I still prefer Miru and Yumi Shion, but undeniably she has a really slender and tight body and she probably can act better than the former 2 girls.
It also surprises me because she is supposedly just 19 years old, but strikes me as much more matured. Her next video will be SSNI-429.
