Kiri has had it "sealed" for a while, but not in a host. The rules say, "Bijū can only be hosted in an object other than a proper host for no longer than one week. Otherwise they must remain sealed in a host, or be treated as a summon."

So, can we do something about this? I'm not necessarily after it, but it isn't fair for them to just have it sealed in some container for months either.
