On this episode, Akechi's past involvement with Twenty Faces got revealed more. Later, Akechi solves the mannequin case and explains about Twenty Faces.
Whoa, the Twenty Faces' origin is quite interesting and it's probably the main plot or is a group of antagonists of the series. Also the mannequin case was kinda short when they solved it already in the beginning of the episode. Other than that, I wonder who will be the next Twenty Faces that our male lead will face against. Now what's going to be the next case for our group? Overall, mannequin case solved and interesting origin of Twenty Faces.
Conclusion: Mannequin case solved and interesting origin of Twenty Faces.
