Someone calculate how long it will take her to run around the planet. Or how fast she'll deplete all oxygen.
On this art, you can notice cirrus-cumulus clouds, which allows you to determine the approximate height of the girl: such clouds belong to the upper tier and are located in the range from 7 to 18 km. Hokkaido Island and the northern part of Honshu Island lie in a temperate climate zone, hence the height of the clouds in question is about 8 km. The clouds are about ankle-high. From this, we can find out the approximate growth by focusing on drawing tutorials that can be found on the Internet. I dare to assume that the height of the Shimakase is in the range of 150-160 cm, therefore in this case its height is about 168km. With this growth, its mass will be about 5.5 thousand tons (if compared with the table of normal weight for girls with a height of 155 cm) A group of British scientists conducted a study and calculated that the weight of all people is 287 million tons. Add to this the mass of the giant-girl and nothing will change much. So the answer to the question is: Shimakase will not use up all the oxygen. As for how long it will run around the Earth, you can compare the speed of a person's running and his growth with the growth of 168 km of Shiamkase and find the speed. Personally, it turned out that she would run along the equator in just a minute. However, this cannot be the correct answer, because air resistance, physiological factors and so on were not taken into account.

Wait... Let's be conservative and say at normal height, she's 45kg (100lbs). If she's 168km in the image, that's an increase of ~108 387 times her base height (155cm). Just multiplying her normal weight with that number would give 4.9 thousand metric tons. Which is indeed in the ballpark of your calculation.
But mass increases cubed. Because while her height increases only in one dimension (upwards), her body (and thus her weight) expands in 3D. That would mean her total weight here would be about 57.3 trillion metric tons (a 13 digit number), or about a 100 times more than all alive biomass on Earth, including all plants (alive biomass calculated to be about 550 billion tons by scientists from 2018).
Sorry, my mind just went off as 5.5 thousand tons is less than what the Titanic was, and no way a girl with her ass almost in space weighs only that much.

Fuck, I really should be doing other things, but assuming my earlier calculations are correct...
The Earth's atmosphere is about 5.15×10^18 kg. 23.5% of that is oxygen by mass (1.21x10^18 kg, 8.48x10^20 liters). The human lung consumes about 250ml of oxygen per minute or about 0.36 grams. For scaling, let's take Kleiber's Law. It states that for animals, metabolic rate (and thus, oxygen consumption) scales with body mass to the 3/4 power.
Crunching all these numbers together, the giantess is consuming over 53 billion liters of oxygen a minute or about a third of India's daily natural gas consumption or 20 thousand Olympic swimming pools.
What's crazy is despite the immense volume, even on this scale it would take 30 000 years give or take to deplete all our oxygen. Also, if you stood next to her face, her breathing would only feel like a summer breeze because of how huge her nostrils are. (With a nostril area of about 2.3 million m^2, scaled up from 2 cm^2).
... So the answer to the question is: Shimakase will not use up all the oxygen. ...
If her height is 168km though, this part is true though regardless of her mass. Mainly because 168km is in the thermosphere and high enough that the ESA regards it as low-earth-orbit, and there won't be enough oxygen around her mouth and nose for her to use up. Normal humans with much lower oxygen requirements require supplemental oxygen at just 4.6 km. She'd unfortunately asphyxiate very quickly.
