Otome Yokai Zakuro takes a slightly different approach this episode, one
that works in its favor in a lot of ways. After returning from their
previous mission as seen in the last episode, Kei and Zakuro are told to
take the day off rather than go on the next mission since they need to
be rested and not overworked. That in itself isn't a bad thing but what I
like is that Kei has once again found himself being saved by Zakuro and
he takes it in stride but intends to continue training himself so that
she doesn't have to do it. But he does that in a way that avoids being
either shy about it or making a bigger show of his training. It's
another element of the show done in a realistic fashion which is very
important to have when half the show is focused on unrealistic things
The mission this time around again feels fairly inconsequential as it's just something that allows the characters to interact with others. The remaining group heads off to an antique shop to investigate what's going on and it's nicely revealing as they make their way. The suspicion and uncertainly of your average citizen is still very much apparent as they look on the procession with either disdain or fear. Few of them smile really since there's still so much distrust and a long history to overcome. One of the soldiers, Riken, takes it in stride though and offers to lead the way, allowing the young female yokai to be protected and feel safe. It's a typical high school kind of moment where she realizes how large his back is, but it's something that again paints the picture of a society dealing with strong racial prejudices that are hard to hide. The tension is nicely done and is something I'm impressed to see used episode after episode so far instead of dropping it so things would move more smoothly elsewhere.
While there are some decent little interpersonal moments and a nice balance of humans and spirits working together in harmony, the focus on the item itself that comes into play is rather fun. The sword that's bandied about as the potential problem has a lot of history to it, something that Susukihotaru finds herself very trouble by. Through it she sees some of its past and it has a distinct effect on her when it comes to others and she event ends up essentially possessed by it, leaving Riken to try and rescue her. While it could be played big with lots of effects and action, instead it plays out in a small room with an almost quiet intensity amongst those involved. The music ratchets it up a few notches, but it stays appropriate and works very well in providing tension, especially after the way Susukihotaru and Riken started to get mildly closer in a way that's appropriate for this time period and their social standings.
