The First World War of Sorcery

The male lead was a mercenary on the Russia-Ukraine front. Out of the blue, the Russian military urgently reassigned him to serve as a police officer in a remote Siberian town where hardly anyone lived.

Just as he was hesitating, his girlfriend from the front line, the star performer of the Katyusha Song and Dance Troupe, forced him into marriage.

After he took up his post, his former classmates from Agricultural Science Class Four came flocking to join him. They planned to grow potatoes on a massive scale in the town. They thought this was the start of a wonderful life of getting rich, but something else lived in the dark forest surrounding the town...

Only when some unknown creature started stealing the potatoes they had planted did everyone realize that overnight, they'd changed careers and become fairies.

The Russian educational title of this book is: [What Kind of Person Is Suited to Growing Potatoes?]
