Mahouka Koukou no Rettousei - ep21

Now with what appears to be the final preparation being put into place with the test of the experiment. This leads to exposing the spy that got away last time but this time around she doesn't escape with Mibu, Kirihara, Leo, and Erika giving chase. Although this time she is armed, even with this she is still taken down. It also seems like that she isn't the only potential spy since Sekimoto is also acting suspicious because he is trying to make a big deal of Erika and Leo's involvement because of their course two status. That he is trying to get them barred from the premise, then you have the fact that when they leave Kanon gets a call about Hirakawa Chiaki the spy waking up which cause Isori to leave with her. Then when it appear that everyone is out of sight, it looks like Sekimoto tries to steal their work but is stopped by Ichihara.

Now with Chiaki awake, she is question on what she was doing. It seems that she was trying to sabotage the experiment to get back at Tatsuya because of what happen at the Nine School competition during Fairy Dance. That her sister has to take responsibility for what happened even-though Tatsuya could have prevented it. Then Isori tries to express that all the engineers were all equal responsible that it is unfair to just blame Tatsuya. Then when they inform Tatsuya, he decides that it should be left alone. The reason being it cause things to escalate while also implying that Chiaki wasn't the only one that was loitering about. That there are still greater threats out there because it is doubtful that she is the one that hack into his system.

The other main issue that takes place during this episode is how Leo and Mikihiko are preparing themselves for the future conflict that is coming. First you have Erika training Leo to making a more competent fight by giving him a killing technique. Since she feels that this is necessary if Leo is serious about involving himself further in what has been happening. That he needs to be prepared to take a life and he needs the skill to do so. Then you have Mikihiko who is training with the security forces for the event. Although you also have a bit a love in the air with Tatsuya implying that Erika and Leo taking the day off together is no coincidence. That this implication of romance between the two also cause Mizuki and Mikihiko to become self-conscious of one another and this cause them to reach their breaking point towards the end of the episode. The question is how much longer are they going to hang around the First High School before heading off to Yokohama.
