Pyonko-Hime is the boisterous leader of Team Usagi, commanding General Rabbit and Kabamaro while fiercely rivaling Joe Kirifuda. She sports a short stature, exaggerated comical features, and signature head-mounted goggles. Despite her youthful appearance, she concealed her age in official records after hunting rare cards for 30 years with her team, sparking speculation about her humanity. Her personality blends arrogance, loudness, and cowardice, often alongside her teammates; she is easily deceived yet harbors a fervent romantic obsession with Johnny, crafting chocolate for him during Valentine’s Day.

Initially infiltrating Lulu Takigawa’s bar to steal Joe’s cards, Pyonko-Hime dueled him using extreme Shield Trigger luck to eliminate his Jokers. She lost when Joe summoned The Ramen and exploited her creature attacks with Bainaradoor, triggering Johnny’s automatic win. In a later clash, she pressured Joe’s forces with Gashagozra, Misfortune Demon 03 and Spike 7K, Ganzan Tank, only to be defeated by a Time Stopon Shield Trigger. After Team Usagi’s home was destroyed, they relocated to Lulu’s bar, where Pyonko-Hime dueled Joe again. She empowered Maruhavaan, Red Attack Silver into an invincible Slayer Blocker using Gashagozra, but Merabeat the Johnny secured her defeat.

Her Fire Civilization Beat Jockey-focused deck evolved to incorporate Darkness Civilization cards like Gashagozra, Misfortune Demon 03, making her the first new-generation duelist to wield multi-civilization strategies.
