Set your in game clock to tomorrow at 5:58Am that will give you time to save and go to the title screen
At 6:00am you create a new character
Then you go to your camp, no camper = power off. And create a new character again until you get one.
You'll need to repeat the process until you get the villager you want, like if you want Apollo you reset your camp until you get him, if you lets say find muffy in your camp reset because it's not apollo, he'll eventually get on the camp, for me it took about 5 hours to get beau in my other town worth of resetting but it's totally worth the time and effort you put into resetting.
Or you could just go a full day without playing then the next day create a character on the start screen.
My advice i personally use: when the day is almost over i go into the ds clock and make it go back a few hours to equal what would be 6-7am in AC time so i have time to sleep and all without having villagers move the next day or something and becausee some days ARE REALLY high chance of a camper than others. Then when i'm sure the villager is moved in i carefully start correcting the clocks.
KINDA long explination but it's detailed also what i do when i reset, i multi task so i when im creating the character i'm not bored. and when you have apollo just make a house for that character save, load the mayor ask it to move in, then delete the other character unless you make it a pathway mule then you don't have to
