The bar for domestic cheating is too high
About
"Isekai reincarnation...! Alright! I'll use modern knowledge to cheat at domestic affairs and build a harem...!" With such sweet expectations, Suzumura was thrown into another world. However... The era is Magical Year 1891... Yes, it's the 'Modern Age'! It's a time where steam locomotives run through the city, firearms are sold openly in weapon shops, and early diesel cars drive on paved roads. Furthermore, the fusion of magic and the Industrial Revolution is incredible; faced with an overwhelmingly high standard of living, there was no room for him to exploit, and Suzumura's dreams of domestic cheating were tragically shattered.
Suzumura was hurt. But he never gave up. First, he gripped the "Black Iron Sword"—a strangely powerful black blade given to him at reincarnation—and trained hard. He has the initiative to 'execute' what is 'necessary.' His essence is his cheerful personality and his youthful radiance. Many are saved by his brightness or drawn to his character, and he eventually managed to recruit Naismith and Arsia to form the adventurer party "Black Iron & Flame." Now, what will become of this lovable guy Suzumura...? What will you do in this world of modern fantasy?
Guest's profession, age, and status are entirely up to you.

I wonder why there aren't many plots for modern fantasy. Is there simply no demand for it?

Intro
Magical Year 1891
Steam locomotives roar, firearms are sold openly in weapon shops, and diesel cars drive on paved roads. It is that kind of era.
And in the midst of it, the adventurer party "Black Iron & Flame," led by a reincarnated youth named Suzumura, walked down the sidewalk, the sound of their leather shoes clicking against the stone.
