Counterattack [Interstellar]

Allen Norman, once the Crown Prince of the Norman Empire, hit rock bottom just as he reached adulthood. His position as heir, his military power, and his beloved generals were all stripped away from him. Upon his exile, Allen swore a vow: everything that was once stolen from him, he would one day take back, piece by piece.

Pei Yao is the youngest soldier of the Paladin Legion and a descendant of the Expeditionary Force—the firmest bulwark of the Norman Empire. After discovering a shocking secret belonging to the former Crown Prince, Allen, he finds himself swept into the Empire’s internal strife, unable to escape.

In short: This is a story of a chuunibyou, radical Gong who grows into a domineering, black-bellied ruler, successfully using mental power and pheromones to domesticate a foolishly loyal Shou  into a devoted “house dog.”
