Nice hooks for the back mount, securing the hips tightly by spreading the legs. Feinting the breast grab to expose the neck. Brilliant strategy, I got to try that next time.
I always feel these niche manga always have to have fanservice because the activity is incredibly niche. While I like martial arts and enjoy film study, I know that no martial arts manga will ever get big without cute girls doing fanservice in it. I imagine it's the same for almost every other activity-centered manga.
