True. But Ise has established his intent to lose his virginity and also his great obsession with breasts. Rito is just Rito. He's mostly just there for being the source of the "Yuuki Rito syndrome" that plagues harem manga and even infects Ise at times.

Harem-wise though, Ise actually works much harder and has earned many severe injuries not to even mention having his whole body destroyed. Rito just needs to walk around town a few times while Lala throws inventions on the street to conquer a girl. Both of them do have harem managers though but admittedly Rito's one is more devilish even though she is an alien Devil and not a biblical one =P
