Dr. Kensaku Ijuin:  First you come and see me to warn me not to make an Oxygen Destroyer ... now you want me to make one ?
Kenichi Yamane: It 's the only way Godzilla can be destroyed now ! Every other means has failed ! You 're the only one who can do it !
Dr. Kensaku Ijuin: I said I could make _ one _ , but I did n't say it was going to be easy , did I ? Besides ...
Yukari Yamane: Besides ?
Dr. Kensaku Ijuin: I made an analysis of the surrounding soil . I 've seen the effect the Oxygen Destroyer had on it . If it had have been used on the ground , it 's quite obvious that Tokyo would've become a cemetery .
