Tezuka! I think your idea of adopting a child in need is a lovely thought, but are you sure you've really thought it through? I brought this doll back from the hospital; it's called 'baby think it over' and it is an infant simulator. You can 'care' for the baby using a special key that mimics nappy changes, feeding and comforting.
Unfortunately .... they're quite in the demand over the summer ... so I was only able to get the drug-addicted version. It might be a little bit harder to care for than the other ones, but I'm sure you'll do well! It'll give you and Atobe a feel for what you might have to give up in order to bring up a child.
