A 185 whose chuunibyou phase isn't over yet discovers a family secret? What secret lies hidden in the golden spearhead? As a magic circle slowly opens, who should emerge from the golden light but... an absolutely gorgeous man?!

Brush: "Are you my Master?"

185's inner thoughts: Jay, I summoned a demon king from another world and became a magical boy!!!

The Demon King is gorgeous w.

Brother Brush kneels on one knee. "Very well. Diarmuid, Berserker, the greatest warrior of the Knights of Fianna. From this day forward, I shall serve as your Servant."

185 removes the bandages covering his eyes, looks down at the man before him, and grins. "Remember your words, Diarmuid."

Brother Brush: "Yes, my master."

*

Back on the Throne of Heroes, Diarmuid can't stop thinking about how his former Master betrayed and abandoned him.

His frenzied hatred directly changed his class from Lancer to Berserker.

Then he is summoned again, and sees his Master's starry, brilliant blue eyes and peerless beauty...

Diarmuid, the Master-in-Law's Fiancée Collector, decides! He will stay far away from his Master's fiancée until the Holy Grail War is over!

Then he realizes...

This world has no Holy Grail War, and no other Heroic Spirits. He can't go back to the Throne of Heroes, okay?!

5T5: "Does Diarmuid want to abandon me and return to that cold Throne of Heroes?"

Brother Brush: "...No."

*

Ever since 5T5 got a Berserker, he's been showing him off everywhere, flaunting his Servant and making all the other Mafiosi suffer through his displays of affection.

The children taught by 5T5 are the first victims of all.

Tsuna & Yuji & Junpei: Thanks, but we're used to it.

About Berserker indulging his Master, the Mafiosi only have this to say: "Berserker!! That's not spoiling him, that's doting on him! Do you even know what that means?! You've completely spoiled him rotten!!!"

Brother Brush: "...Oh."

5T5: "See? A gorgeous man who can be elegant, cook, write, fight, and stay loyal. He's mine, all mine!"

The Mafiosi: "Get lost!!!"
