Here's what I found: (you can thank our admin FF_G for these which come from her site:

FF7 Dismantled
"Actually, we had only Aerith at the beginning, and Tifa did not exist. But on a Sunday evening, I phoned the director Mr. Kitase and suggested, 'Let's kill Aerith and put in Tifa' (laughs). So, now we have two heroines, and we have an event where one of them dies."

Interviewer: "FFVII had a story depicting death, what with the heroine being killed by [Cloud's] old foe, Sephiroth, wasn't it?"
Nomura: "Yeah. There are people who believe that I thought of the scenario where Aerith dies, and I've had some rather strong attacks from some (laughs). In a strategy guide interview the core part was left out, and only the joke bit ended up being published. I told them 'hey, that's not right', but it was too late. I suddenly became the villain of the FF staff (laughs)."
"To tell you the truth, FFVII's theme was 'life'. We had instructions from Mr. Sakaguchi saying, 'More than depicting life in the theme, you have to depict life and death. Anyhow you have to portray death.' With the death of a character, we wanted to have the player feel pain. So to do so, portraying the death of the heroine Aerith would be the most painful and important/heavy [on the feelings/emotions]. So, to portray death properly, it was decided that we would show Aerith's death."

"In the real world things are very different. You just need to look around you. Nobody wants to die that way. People die of disease and accident. Death comes suddenly and there is no notion of good or bad. It leaves, not a dramatic feeling but great emptiness. When you lose someone you loved very much you feel this big empty space and think, 'If I had known this was coming I would have done things differently.' These are the feelings I wanted to arouse in the players with Aerith's death relatively early in the game. Feelings of reality and not Hollywood."
Aerith, this must be what you are looking for:
Actually, his name is Galuf. You can read more about him here:
