If I'm exposed to fresh air,

What kind of death is that...

I die... once all my fluids leave my body.

Aya, you're too naive!

This "Hutate" is a completely closed-in room! It doesn't let fresh air pass through!

The naming is bad, but if you have a ventilating fan, it's no longer closed in... Hattate-goya is a pun on Hottate-goya, a hut/shanty.
