As funny as the surprise switch to De:Lphinus was, I didn't expect the chapter to be satisfying, but now I want to see more of them too. Odoro Dorothy just does not miss, each chapter is such a treat.
is having that big an age gap in an idol group a thing? I don't really pay attention to them much but I would expect a 16yo and a 22yo to be in different groups based on starting so far apart if nothing else.
The typical gap between the senior and the youngest member (in Korean idol groups at least) is usually 4 years or less. But 6 years is not unheard of, that's the gap in e.g. LOONA.
I assume that the larger the management company, the more trainees, which means more trainees in the same age cohort, and a smaller gap between members in the same group. Blockberry Creative, which managed LOONA before their departure, is a subsidiary of a larger conglomerate, but they are a small operation, as their only managed group was LOONA between 2016 and 2022.
