I'd say Tae too. She loved Kurono for who he was in his real life. She genuinly loved him, even though he was a loser. So much that even Izumi couldn't do anything. She even sacrificed her own life for him.
And it's clear that he loved her.
Reika saw him act cool in a mission and began to have the hots for him. She didn't even know him that well.
Sure, she said that she loves him, but I don't think it's real love. Probably just a form of admiration, that she thinks is love. Paired with the danger of dying any second and seeing someone that looks really strong.
But if Kei had passed her on the street before Gantz (or she would've met him) she wouldn't have even looked at him twice.
