The Valvas estate had transformed into a hub of energy, learning, and camaraderie. For the next two years, Roy dedicated himself fully to training alongside his first and second peerages while also enjoying rare moments of relaxation with his closest allies.
Rigorous Training
Every day, Roy trained with his peerages:
Swordsmanship and Magic Mastery – Roy sparred with Scáthach, Astoria Saber & Lancer, Modred, and Irene Belserion, refining his techniques with Ryūjin Jakka, Kyōka Suigetsu, and time magic.
Team Coordination – Lavania Reni, Kuroka, and Koneko continued to hone their combat synchronization, perfecting Absolute Demise, shadow manipulation, and lightning ninjutsu.
Peerage Strategy – Grayfia, Medusa Rider, and Irene Belserion helped Roy train tactical maneuvers, defense formations, and battle coordination, turning both peerages into a perfectly integrated war machine.
Over time, Roy's Ultimate-Class Devil abilities grew, and he broke through to Satan-Class Devil, a feat unprecedented for an 11-year-old.
To the outside world, however, Roy only revealed that he had reached the peak of High-Class Devil, leaving even the most powerful devils shocked at his apparent youth and power.
Only a select few were privy to his true power:
Darius Valvas
Clara Valvas
Zekram Bael
Both first and second peerages
Moments of Joy and Bonds
Despite the intense training, Roy never neglected his close relationships:
He spent quiet afternoons with Seekvaira Agares, Latia Astaroth, Iryuka Glasya-Labolas, Sona Sitri, Serafall Leviathan, Grayfia Lucifuge, Rias Gremory, and Venelana Bael, playing games, sharing meals, or teaching them small combat techniques.
Kuroka, Koneko, and Lavania Reni trained under his guidance and also enjoyed playful teasing, competitions, and moments of affection with Roy.
The second peerage—Scáthach, Irene Belserion, Medusa Rider, Astoria Saber & Lancer, Modred, and Kaguya Ōtsutsuki—grew closer to him through both sparring and personal mentorship, their loyalty and admiration deepening.
During these years, romantic tension began to blossom:
Grayfia Lucifuge, Lavania Reni, Kuroka, Koneko, Sona Sitri, Serafall Leviathan, Seekvaira Agares, Latia Astaroth, Venelana Bael, Rias Gremory, Scáthach, Irene Belserion, Medusa Rider, Astoria Saber & Lancer, and Kaguya Ōtsutsuki all developed strong feelings for Roy, each in their own way.
Roy, ever patient, took things slowly, nurturing bonds without forcing anyone, while subtly teasing them and deepening their trust and affection.
Meeting New Royals
During this time, Roy also met:
Rias Gremory, Queen Akeno Himejima, and Sona Sitri's peerage Queen Tsubaki Shinra
Both Akeno and Tsubaki developed crushes on Roy after seeing his leadership, charm, and genuine care for everyone around him.
Roy, of course, handled their attention tactfully, maintaining his calm demeanor while playfully teasing them on occasion.
Power Concealment
While Roy's Satan-Class Devil strength was now absolute—able to rival some of the most powerful devils of the Valvas era—he deliberately kept this secret from the outside world.
To humans and devils alike, he remained the 11-year-old peak of High-Class Devil, earning admiration and disbelief from everyone.
Only those he trusted—his grandparents, Zekram, and his peerages—knew the truth about his overwhelming power, making him a silent guardian and strategic genius.
After two years of training, relaxation, and growing bonds:
Roy had become a tactical genius, Ultimate-to-Satan-Class Devil prodigy, and mentor.
Both peerages were fully integrated, loyal, and extraordinarily powerful.
Romantic bonds and trust between him and the members of his peerages, allies, and friends were stronger than ever.
Roy was now ready to face the next major threat, wielding both peerages, his immense power, and the loyalty of those closest to him.
The Yaksha of Valvas had truly come into his own, yet the world remained oblivious to the full extent of his strength... for now.
