Ashley, the Emperor’s seventh son, is an unfortunate young man born with unsettling “abnormalities”, dragon’s eyes and white, inhuman arms.

His strict older brother trains him in swordsmanship and urges him to make it as a soldier, but Ashley’s talents lean far less toward the sword and far more toward the handling of a shovel.

One day, while excavating, Ashley digs up the Evil Dragon Jirant. The dragon transforms into a girl with the same dragon’s eyes as his and gives him a single book.

“This is a guidebook,” Jirant says. “Each time you complete a task, it grants its owner explosive growth. From here on… I will make you an Emperor.”

A prince whose birth was never celebrated, who lives in constant fear of assassination, carries this strange tome that demands the punishment of evil. He sets out to purge the corruption festering throughout the Empire—

Not with a sword, but with the shovel that pierces through everything.
