On this episode, Kogoro attempts to stop Namikoshi's Twenty Faces scheme. Later, more chaos appears.
The ending was pretty interesting and is kinda strange in a way which is alright. Seeing Kogoro doing his attempt to stop the Twenty Faces plan is cool. Also the chaos around the plan was getting worse and made the finale a bit more intense. Other than that, this mystery series is not bad on everything except for the abusive girly acting Kobayashi. Although I doubt there will be a sequel coming since the original author has been long dead. Overall, cool finale and ending after result.
Conclusion: Cool finale and ending after result.
