^ yeah lol.. ridiculous! If you really want japanese versions, better be prepared to pay a lot.. I would personally recommand to find an auction of both To LOVE and LOVE One together, it'll be much cheaper.. I would also recommand to check mbok.jp, they often have cheaper auctions, like this one:

To LOVE is not that hard to find, and at a reasonable price
good luck anyways!
