Tension from last episode was good but this one was insane. After infiltrating the palace we meet the shogun only to be supported by none other the Oboro and his clan. Gintoki and Oboro know each other from their perspective past which also is intriguing as we see more of Gintoki's past as the author keeps giving us glimpses and glimpses of it making us want to question what happened in his past. What's also so good about this is usually when a shounen character is angry they usually get a power boost but not for Gintoki. Him getting angry which makes him lose control and focus, if we can't control our emotions our movements are unstable, Gintama simply applies this logic. Let's not forget about the badass scene with Gintoki attacking the shogun, so fast and he bites a sword, legendary. Also good ending to this episode, both police forces arrive.
