Natsume finds his way to Mikan's balcony... Mikan says she doesn't have a present to give him in exchange for the christmas present he gave her, so Natsume asks for a kiss instead. He then gets the super embarrassed Mikan to confess her love for him, and she gives him her special alice stone that she created using all the love in her heart... Natsume says this completes the proposal ritual that he started with his alice stone he gave her... they kiss again, under the full moon as their witness...
Ruka finds Natsume and he tells him about how he met Mikan.. Ruka is worried about Natsume's health which has gotten worse than ever now.. but Natsume wants to rescue Mikan no matter what even if it means his life will be shorter. He doesn't want to make the same mistake Narumi did.
Shiki explains how when he and Yuka took the alice stones from ESP's clones, then they joined forces with the rebellious ESP clone, the leader of Z, they gave Z all of those clone stones, and he became strong enough that he could control all of ESP's other clones... or something like that... so Z has become a bigger enemy than even ESP was.
And it seems Persona has joined Z now, and is trying to gradually gain power within Z to eventually take it over... and he has allowed Reo and other Z operatives to enter the academy. Shiki summons Narumi and gives him the job of being a spy, working for both the academy and Z to find out what's going on and stop Persona... I think Persona actually hates the ESP now because he is preventing Mikan from being able to use her powers to save Nobara. Meanwhile Reo and the other Z people are plotting to kill ESP.
Later, Natsume beats up the mind reader kid for revealing that he is now engaged to Mikan.. The high school council guy confirms that everybody still has the extra alice stones Mikan inserted into them back when they were hiding in the high school... Akira has Amplification, Tsubasa has pheremone, Ruka has Barrier, and Natsume has "Wish".. they are planning to let Z carry out their plan to take out ESP, and then in the chaos they will stop Z as well.
Finally Reo's concert starts, and he tries to brainwash everybody into wanting to kill the ESP... but instead everybody just collapsed. The ESP comes up to Reo and mocks him for failing his betrayal plan.. it seems ESP now has control over the clone that is in charge of Z.
Then Narumi grabs ESP's neck from behind.. he has some kind of poison alice similar to Persona's... Mikan catches the concert on TV just as this is happening.. Narumi threatens ESP's life and tells him to reveal all the shitty things he's been doing... It seems like the HSP has ordered people to turn off the broadcast, since Narumi got involved just now he fears that this could be connected back to Shiki...
Narumi does a long, poorly translated speech, MIkan cries as she sees this, and wants to go stop him but Bear stops her...
