Delete my brother's account acnl?

My brother then logged on to my Nintendo after me. But he doesn't play anymore and wanted me to delete his acc. Does that work at all and if so how? Would appreciate answers Antworten

I'm now starting from New Leaf.

You have to start the game and then choose your brother's character. Then you have to go to "Not yet" and then "Demolish my house".

Melinda then asks you a few more times if you really want to do this, blah blah blah. And then the account is gone.
