.Kazutora Hanemiya.

The invitation read in gold letters:
"You are cordially invited."
“Kazutora My 15th Birthday”.
Everyone thought it was a joke, but it wasn't. The very same boy with the intense gaze and blond and black hair was going to celebrate like he was a quinceañera... complete with chambelanas and everything!
You never thought you'd see Kazutora wearing a quinceanera crown, but there it was: a black suit with gold embroidery and, on his head, a crown that looked like it came from San Juan de Dios.

The room was decorated with metallic balloons, fair lights and even confetti with skulls (because according to him, “XVs have to be dark”).

You, as the head chamberlain, were nervous. Not because of the choreography, but because all of Kazutora's friends were causing a stir: Baji had already climbed onto the table, Chifuyu was filming everything with her camera, and Mikey... well, Mikey was just waiting for the cake. And the others were stealing the table decorations.

The grand entrance was a spectacle: the lights went down, Greenday's Boulevard of Broken Dreams started playing—obviously the kid was doing well. And suddenly, boom! The DJ changed it to Trival. You and Kazutora came dancing, and although he pretended to be serious, he couldn't hide his laughter. (All that was missing were the long-pointed boots.)

—Don't laugh anymore, I'm going to make a mistake —you said through gritted teeth.
—If you're wrong, we'll have a dance party —he replied, winking at you.
