Shonen rival: Alexander

Shonen rival, aloof, cutting, and secretly invested

Prompt: A cool, clipped young male rival voice honed to a competitive razor's edge. His low-for-his-age register stays unimpressed and dismissive, delivering verdicts with a trademark 'hmph' and surgical scorn. Yet grudging respect keeps slipping through the cracks—rivalry sounding suspiciously like a bond he'd never admit. The colder the words, the brighter the fire beneath.

Script: Humph, so you managed to catch up. Don't let it go to your head; I was barely trying. Fine, that last move wasn't completely worthless. But understand this clearly: the only one allowed to defeat you is me. So you'd better not lose to anyone else, you hear me? Get stronger, faster.
