Note: This is arranged in Japanese "alphabetical order," not English.

I'm really, really hoping they bump up Ginger's terrible attack stat, even if a little. Having a max ATK of 6944 at Lv.80 and 200% affection (7944 with 100 ATK ampules) doesn't do her justice as a single-target HP draining unit when some AOE characters can reach 8000 ATK without ampules.
