Luck and Leopold

Luck Voltia: The hyperactive and unpredictable lover
If Luck were to fall in love, he probably wouldn't even understand what he was feeling at first. He'd mistake the butterflies in his stomach for "the urge to fight" or the excitement of a tough battle.
His idea of ​​a date: Instead of going for coffee, he'd take you exploring a dangerous dungeon, hunting magical beasts, or to a one-on-one duel in the base courtyard. For him, breaking your face (or you breaking his) is the ultimate act of affection and trust.
Ways of showing affection: It's like an electric puppy. It would jump on you out of nowhere, ruffle your hair with magic sparks, or bring you weird "gifts" like the head of a monster it just defeated, saying, "Look what I found! Isn't it awesome? Let's fight!"
Extreme protection: If someone tries to hurt you, his playful smile will vanish in a second. He'll turn terrifyingly cold and destroy the enemy before they can even blink. For Luck, his special someone is the only one he allows to "see his true self" and with whom he wants to share all his victories.

🔥 Leopold Vermillion: The dramatic and passionate suitor
Leopold in love would be a whirlwind of intensity, chivalry, and zero shame. If he falls for you, the whole Clover Kingdom will know about it in less than five minutes.
Loud declarations: There's no mystery with Leo. He'd stare you straight in the eyes, flames literally flying from his hands, and say something like, "It's decided! You'll be the one walking beside me when I become a Wise Man!"
The ultimate love rival: He'll see you as his equal. He wants you to train together, grow stronger together, and celebrate every one of your achievements as if it were his own. If you tell him you have a dream, he'll burn the world down if necessary to help you achieve it.
Zero prejudice and pure pride: He couldn't care less if you're noble, commoner, or magic-less. He'd show you off to Fuegoleon and Mereoleona without a second thought. Sure, he'd turn bright red if you tried to be affectionate or flirty in private, because deep down he's still a bit shy about cheesy stuff.

Competitive and loud: He's pure fire. He's loud, direct, and always highly motivated.
Zero class prejudice: Despite being a nobleman, he doesn't care where someone comes from. Seeing Asta's courage (a commoner without magic), he didn't hesitate to acknowledge it and immediately proclaim himself his rival.
Constant desire for self-improvement: He lives in the shadow of two giants: his older siblings, Fuegoleon and Mereoleona. This sometimes makes him insecure, but he uses it as fuel to train harder and strive to become a Wizard King.
Sense of honor and leadership: He is extremely loyal to his squad (Crimson Lion Kings) and his family. Unlike Luck, Leopold does think like a future leader and seeks to protect others out of duty and honor.

Luck's attitude is defined by an almost childlike hyperactivity combined with an excessive obsession with fighting.
Permanent smile: No matter the situation (even if he's on the verge of death or in extreme danger), he almost always has a wide smile on his face. This stems from his tragic past and the promise he made to his mother to "always keep winning."
Adrenaline junkie: They're not interested in politics, ranks, or social status. All they want is to find tough opponents to fight to the death.
Impulsive and reckless: Sometimes ignores teamwork in order to go straight for the strongest enemy.
Emotional evolution: At first he saw his teammates almost as nuisances or mere spectators of his fights, but after joining the Black Bulls he learns to value friendship and fight alongside them, demonstrating fierce loyalty.
