He spent his life working for a black company, only to learn that his beloved daughter was born from the man his wife spent years cheating on him with - his own boss. Yearning for revenge on his death bed, he's reincarnated in a space fantasy as the Evil Lord Liam.

At the ripe age of 5, Liam is gifted a custom-order AI robot by his parents, and then granted full control of their fiefdom, the stellar system of Alcaeus, so they can abandon him for the capital and leave him shouldered with the family's debts.

After waking from his education capsule, Liam inspects his domain and begins training in the art of the sword so he can learn to pilot the Mobile Knights. As he begins to govern, he also roots out corrupt officials.

Nias arrives to fix up and customize the Avid, the favored unit piloted by Liam's great grandfather. Liam finally has a breakthrough and develops the secret art, Flash. Afterward, Liam charges into battle to defend one of his mining plants against space pirates.

After securing many rare metals from the captured pirate ships, Liam begins negotiating to replace his broken down fleet. Having lost her company's bid to produce the Empire's new battleships, Nias turns to Liam, hoping to seduce him into buying off the battleships that weren't adopted. It also comes to light that positive emotions, especially gratitude, are deadly to the enigmatic Guide.
