The only girl you have to worry about that is actually Kuroka because she would eat Issei alive if you don't believe me read Volume 11 because everytime Issei deals with Kuroka he has to bring Koneko as a insurance policy to protecting his chastity because I hate to say this but Kuroka is not as innocent as Akeno in terms of experience because she knows exactly what she is doing, and she also knows to push the buttons of any guy to me she is a master seductress never let your guard down when you are with her to me she is equivalent to a succubus. The scary thing about it is that Kuroka might be interested in Issei true she knows that Koneko is in love with him but she likes what Koneko sees in him, and maybe she will join his Harem permanently at some point.
