[wow i was just giving context

mikazuki will just move to put the omamori in his coat pocket - he can't help but feel as though it belongs there - as he watches tsurumaru try to open the others

then he'll move to close the locker again - and hum softly when his attempt to reopen it is denied]

.... I suppose there's no way to find out but to try. Though it would appear as though once it's empty, it will seal itself again.
