Dad is a Great Archmage of Another World (However, He's a Chuunibyou)

My dad pretends to be a salaryman, but he's actually a "Great Archmage from Another World." And my mom is Her Majesty the Queen. And I'm a hero. I'm going to defeat the Demon King! Yeah! This is a story about a perfectly ordinary household in Japan (well, perhaps not ordinary in some ways). I'd be happy if you could relax and enjoy it. I was inspired by "Part 7" of "Boy's Landscape" by Sunago Tamaki, but as I was writing, the world-view kept drifting further and further away, and at this point it's become a work where even asking whether it's "fan fiction" feels rather rude. "Boy's Landscape" by Sunago Tamaki is itself an excellent work, so I highly recommend it to those who haven't read it. https://ncode.syosetu.com/n5240gg/
