To do this you must have all 22 member addresses(includes natsume and tabby, sakubo counts as two)then you will have an email from cc corp.marriage is now available.then you will get a message from aurora. She will give you a greeting card. Send this greeting card to anyone in your member adresses with a color pink with 5 dots in his/her affection. Then play the world but do not log in just exit the game quickly. You should have an email from someone you sent the greeting card to. Check the email then log in to the world and you should warp to mac anu automatically even without going there. There will be a cutscene between you and whom you sent the greeting card.
Feel free to experiment on whom you will send te greeting card to.
