Why does Seele continue to dominate in revenue despite the introduction of many other characters in Honkai: Star Rail?

Honkai: Star Rail is a gacha RPG game with an incredibly effective money-making ability from miHoYo. At present, the developer has released a total of 14 5-star characters, including 7 limited characters. These limited characters have brought in hundreds of millions of dollars for miHoYo.

According to some estimates, Seele is the highest-profit character for miHoYo in the Chinese iOS market. Meanwhile, the character expected by gamers to reach top 1 or at least top 2, Kafka, has relatively low revenue, standing at 5th position out of 7 characters currently.

To give you an idea, Seele's revenue is nearly equal to the total revenue of the next two characters on the leaderboard (Jing Yuan and Silver Wolf), and significantly higher than the three characters following them: Blade, Kafka, and Luocha. 

According to Mytour, Seele's remarkable revenue stems from factors such as timing of release, overall strength, attractive appearance, and her connection with Honkai Impact 3. Specifically, as the 'night butterfly,' she was the first character introduced since the launch of Honkai Star Rail on April 26, 2023, possessing enough power to dominate most game content. Seele also has another variant in the Honkai Impact 3 universe, further increasing her popularity among gamers and driving more spending.

In reality, Seele's current usage has cooled off slightly with only a 60% usage rate in MoC, a 20% decrease compared to before, and lower than several other characters according to statistics from Prydwen.gg. Furthermore, despite the recent release, Dan Heng - Moonlight is experiencing rapid growth, raising the question of whether it could dethrone Seele.
