After Making Cards, I Got Tangled Up with the Villainous Blonde Heiress!

Luvia's notorious reputation at the academy is as famous as her beauty. She is always snatching freshly bought desserts from other students, claiming the most conspicuous spot in the center of the dueling arena, and rounding up her lackeys to hold the "Lady Luvia Cup," forcing every student who passes by to compete. The winner gets no prize, but the loser has to admit that she is the academy's greatest genius...

Except when she runs into Roche. Whenever Luvia confidently issues a challenge, it isn't long before her furious voice rings out across the academy:

"Roche! What is this cat that keeps putting my cards back into my deck?! Last time it was a goblin that kept stuffing my deck with cards, and the time before that it was a cursed deck full of traps! Do you have the guts to face me head-on?!"

"I just want to bring everyone joy with my magic cards!"

"Who wants you to bring them that kind of joy?!"

Luvia decides to name Roche her number-one nemesis, and forbids him from losing to anyone else before she beats him herself. As for why she keeps coming back after every defeat, trying to surpass him in every way? Well, obviously it's to keep an eye on that despicable guy!
