Part of why the reception to this battle has been so polarising - I believe - is because the feats of Shi Ryou especially, but also Shin Kaku Gaku and San Shuu, have come at the expense of Ji Aga in a big way, and Kan Saro to a lesser extent. It's been surprising but also disappointing and anticlimactic to see these Seika warriors made to look so mortal so soon.
