For the Americans in the audience, she's complaining that she's now over 100 lbs. 45 kb (basically 98 lbs weaklings) is considered the "ideal" weight of a woman in Japan. There isn't allowance for being tall, either, although Fukuda is short even by their standards.
For the love of god, tell me you didn't make a typo and didn't mean 45 kg, because sweet lord, that is fucking thin. A big slap on the back would turn her X-Ray picture into a bundle of sticks thrown in a washing machine.
I'm really curious about what is going on here. Yukari seems totally dominated, but I can't tell if its because Akari is manipulating her guilt, threatening to confiscate her smokes, or if thats just their relationship dynamic.
This is probably the most normal thing Greenteaneko has drawn.
Coming from the future, I think you're right. Still, it's nice to see what an artist got up to before their work went Weird™ (or to briefly return to their pre-Weird™ form, like with this piece). (Not that there's anything wrong with Weird™, mind; I know I'm a sucker for it.)
Someone once provided a translation for this, unsure if its 100% accurate so I'm commenting it instead of figuring out how danbooru works.
"Oh Iyozane......" "Won't you help bandage me up as well~? You were ruthless last night." "......" "How surprising though......" "That those injuries have already healed up so much in the morning. (I saw your bones even)" "I suppose that's a *spirit* body for you."
