Yunaka became an instant breakout star from the 2023 tactical RPG 'Fire Emblem Engage' due to her eccentric personality and infectious catchphrases like 'Hiya Papaya!' and 'Zappy!'. While she initially presents herself as a cheerful and slightly chaotic traveler, her hidden past as a lethal assassin creates a 'gap moe' effect that resonates deeply with the fanbase. In the meme community, Yunaka is used to represent sudden shifts in mood, high-energy greetings, or the irony of a bubbly character possessing a dark side. Her expressive facial animations and unique voice lines have made her a staple for Fire Emblem fans looking to inject some chaotic energy into their content.
