TARDIS Communication Network

So judging from all the previous posts, we are on a ship called a TARDIS, trapped in another universe? Would anyone else mind telling me what else is happening? Do we have any sound theories as to why we are all here?

Oh, my name is Urahara Kisuke.

Has anyone seen Ken-chan? I can't find him anywhere! He's really tall and really strong, with big spiky hair with little bells on the pointy ends. He carries around a Zanpakuto, and he wears an eye patch.

Huh? This isn't my classroom! Where is everyone? And what happened to my phone? My contacts list has changed too. Who are all of you?!
