How to use downloaded content on 4U+?

Ok so I have downloaded some contents from the app like games, clothes, foods and characters. How do I use them?

What is outing, livings, decorations, bingo coupons and how do I use them?

And how do I delete the downloaded items? I got a girl but I accidentally downloaded a old man character which i have no idea what's that called.

You have to buy the items from TamaDepa. The downloads you put on are usually marked with a heart I think. Games are found in the 2nd page of the Arcade. Clothes are found in the TamaMori shop. Foods are found in the CafeRestaurant in the Food icon.

Outings are basically destinations you can visit and do whatever it has to offer. Usually you get an item from it too I think.

Livings are backdrops for your 4U. They're found in the Reform section of TamaDepa and you can swap them out.

Bingo coupons are in the 3rd icon. You can download a bingo card and then tap to an NFC point to reveal spaces.

To delete items, open the item and then click the 3rd option. I think you mightve downloaded Creatortchi? I'm not too sure about it but you can just leave him on there if you'd like.
