In the 16 and 17th episode, we can see that Yuto probably lives in Magano since he appeared out of nowhere and left by jumping around, presumably to his hideout, instead of using Magano Gate directly.
Also, in episode 18, we can see Yuto placing flowers on the Hinatsuki Dorm in Magano, waiting for Rokuro to arrive. This means he is somehow, at least, camping there.
Also, according to the wiki,
Abe no Seimei is still alive in Magano
Is it possible for humans to 'camp' in Magano? Do humans who pass through the Magano gate not need nourishment?
