As much as I would've liked to see Busou's retiring match, the fact of the matter is that the focal point of the story is Ryu and his growth, it's his generation that will boast the true performance at nationals, even if it was crucial for the third years, we'll see Ryu, Nabeken, Yuuto and even Sakuraba grow from this loss hopefully. Having experience nationals is also important since freshers will never make to the further rounds. So as much as I had seen this coming, the instant of their loss came much harder than I anticipated since the author left out the match and only showed the after effects, it was that much more impactful, a long drawn out match whose outcome we knew wouldn't have done this manga justice so I thought it was a good decision to be done with quickly.
