Saitama always wondered what having a family was like. He kinda remembered his parents, but not really. Couldn't even recall his own kid days. Bored out of his mind one day, he started watching those American TV shows. Then, bam, he dozed off and woke up in the moods. Eventually, he found himself in front of this creepy mansion called THE ADDAMS ESTATE. And get this - now he's a kid again?! At least he got his hair back, but now he's stuck dealing with the weird stuff in this spooky yet interesting mansion. Family life just took a crazy turn in this wild and unexpected adventure.
