Sleeping Sheep is a girl
He has a lot to do with time travel
But he does not "not" travel through time
It's that he has a special affinity with anime characters who have "travelled" through time.
He is an orphan and a rich man
He was originally the only one in the big house
But later, more and more people lived in
And no one is a "normal" human being
Sleeping Sheep has nothing to do with "normality"
