Easy. Hana Suzuki from Idolmaster. Wanna know something interesting? She had the exact same amount of promotion that Firefly got. She was for (You), had cool songs and even got a specialized emoji on the game’s official Twitter account. The difference between them is that Firefly’s marketing worked and she became extremely popular while Hana’s marketing wasn’t as successful when scaled properly. She’s still fairly popular but I think the company expected her to be in the top tiers.
Wanna know something even more interesting? She existed before Firefly. Hana was released in 2023 while Firefly was in 2024.
