The seventh bondage battle of the mysterious beauty "SPHINX" coming to bind a "strong, beautiful and sinful" woman! The opponent this time is a woman who is pessimistic about being blind and injures her wrist. However, she is a martial arts master with a versatile staff and echolocation that allows her to take in her surroundings. Please see "your world" after the fight!
I bought a lot of these on dlsite - criminally underrated.
Only issue is the author's penchant for diving way too deep into the backstory of characters which you know will never feature again (since each volume is a one-off).
"a fight that bothers SPHINX with a security spray"
Nah, judging from the way she caught her at the end, Sphinx's echolocation is at least as good as the girl's. The artist deliberated between blindness and plot armor, and chose plot armor. ...Still a great story, but I wish the artist was more honest about how OP Sphinx is and stopped always pretending she's an underdog with a possibility of losing. (Oh, and this super martial artist girl can't even stop Sphinx from slapping the blade out of her hand, either.)
