Um... I'm not entirely sure! I've never tried before.
( maintaining curtains was typically a window's job; most of yuuta's experience with barrier techniques was using them in conjunction with his cursed technique when using domain expansion. but he knows the basic rules to it, and they're not all that hard to put up on their own. he tries to estimate. )
Probably as long as I can stay awake...? Unless the person I'm keeping inside of it is really strong and trying to break free. Then it would only last as long as my cursed energy does, but... I couldn't really forecast how long I could keep it up unless I got a feel for it.
Regardless, it's not something that would only work for keeping someone captive! I can keep other people out of a place for a certain amount of time, for example. Just thought it might be useful to bring up.
