In the context of the Pokémon games, when Lyra talks about Cerulean City, she is likely referring to its significance as a location in the Kanto region, known for its beautiful waters and the famous Cerulean Gym, led by Misty. Lyra often highlights the city's charm and the experiences it offers, such as water-type Pokémon and the scenic environment. Her mention of Cerulean City may also evoke nostalgia for players who have traveled there in their journeys.
