Lol at all these vanilla beans outing themselves by calling Yuuki a "simp."
The chapter itself is a great climax to close out the arc. It paints certain earlier scenes in a different light where they sprinkled bits of foreshadowing.
Like in Ch. 3, when Kyouka was teaching Himari how to do a combo on a Shuuki. Then Yuuki playing as "Kyle", who looks like Guile crossed with the One-Horn (the bits of armor, dark clothes, and black hair that looks vaguely like a helmet), got combo'd by Shushu. So of course the real One-Horn gets taken out by Kyouka's ultimate combo.
It's also a nice touch that Riu Myouga shows up in the flashback before being formally introduced a few chapters later.
