This is when Kenta met the female photographer who thinks that there is something suspicious with Marina. For starters, she is quite persistent in cracking the case, and second, she is willing to trespass areas she should not enter, in this case, Marina's dressing room just for her to get the scoop she needs. This is when we learned that Marina is a Tube agent and she is working with the MOTW to turn humans into Angler soldiers! Thanks to the wonder know as flash photography, the photographer was discovered! As it turns out, Marina is actually Fumin in disguise!
But before they can figure out the connection between the pen, Marina and the blood stain on the roof, the photographer is encapsulated in a cocoon and will slowly turn into an Angler soldier. Finally, the Maskmen were able to make a clear connection as Kenta's autograph disappears out of sight. To put it simply, the idol's autograph is the key to create more Angler soldiers! This plan is seriously great, I mean, if they plan on world domination, using the popularity of an idol will make world domination a cake walk as most people will not see anything suspicious with a girl singing in front of the crowd, but then again, if World War II has thought me something about entertainers and world domination is that they pass military codes via entertainment performances.
Now that all of the Maskmen are down because of this misunderstanding, Igam finally appears in front of them, confirming that Marina is indeed an agent of Tube. Now that our dear prince is finally on the scene, we then learned that this is just a plan for Marina to show her true colors! I knew there is something strange with it because we saw Kenta's face when he realized that his favorite idol is part of the bad guys. Even if that is the case, the mutation of the humans into Angler soldiers is almost complete.
After defeating the MOTW in the giant battle, all of the human victims are back to normal, and Kenta decides to treat the photographer for lunch! Guess the lesson in this episode is that looks can sometimes be deceiving. The ones who look suspicious are sometimes the ones you can trust, while the ones who don't look suspicious are the ones you cannot trust.
