@TheGrandMagus I think it shows well that he can do other types of work, though IB already did indicate that. Kaguya made itself mostly on comedy with the larger story placed every so often, while Oshi no Ko, while still comedic at times, uses comedy in the same way Kaguya does with its series moments. It's an element to help drive some chapters but not the core element of it. Which is pretty good to see, since many writers would easily just stick to their genre.
Like take Hiro Mashima as example. Even if his works change a bit, they still are similar in genre. And they do turn into hits, the man knows his genre well, but that's build from experience in it for so long. It's risky branching out into something entirely different, especially if it means that it creates a work that not all of your existing fanbase will enjoy. But luckily Aka seems to be good at it.
