the Kamidake upgrade episode and the one where GXP really starts cooking in terms of power escalation. returning to Jurai to repair and upgrade after the Seiryo battle, the episode manages to make what could be a maintenance stopover feel genuinely exciting by layering in political intrigue and Lady Seto scheming in the background. Seiryo continuing to be wrong about everything at increasing volume remains consistently funny. the episode ends with momentum building toward the final arc in a way that makes you want to keep watching immediately.
