Is it really that cold? I personally feel alright.

Whoa, aren't those,

The girls from hololive? Wearing swimsuits in this kinda weather...

Do they really not feel cold at all?

Or maybe they're going winter swimming. As expected of Vtubers, their constitution is comparable to us seasoned warriors.

I always start wondering at this time of the year, since it's so cold...

Can't I get a costume that covers my navel?
