I'm surprised you guys are talking about how she looked like from the original game, and not the change that was made for the most recent one.

Q: Is it true you said you wanted Lightning-san’s size from a C cup to a D cup?

Nobuhiro Goto (Character Modeling Designer): Toriyama-san said “I want it bigger” so…

Motomu Toriyama (Director): [What a] cop-out! (laughs)

Goto: Yes, it was enlarged.

Q: Was it a C cup until now? Does it even jiggle this time?

Goto: Yes!
