Nami is annoyed and jealous at Akiha, she thinks Kazane favours Akiha and hates her. But the truth is Akiha faces problems and has been working hard, but Nami has been running away, she had a problem past with her model job. She gave up and lost her top model spot to the girl she tries to attack.
The student council are not Nervalists, they are clueless to even Tsutsuji's existance, Tsutsuji has been hiding behind them keeping extremely low profile to spy at the Shishidous.
Aleida warmly welcomes her and thanks her for helping her retrieve Hako-chan, who's very important to Nerval. Tsutsuji is shocked at the huge chunk of metal floating down into the room. Aleida says this must be the first Brain Tsutsuji has seen, and explains that its the central system that controls all functions of this colony, his name is Benkei.
Tsutsuji immediately realises its a 'giant Navi'(damn why haven't we thought of this), but Benkai says not to relate him to those weak little cyborgs.
Aleida explains that Navis are later than Brains and Brains need someone to guide them, a partner and that Tsutsuji is Benkei's partner. Meaning Tsutsuji is Benkei's Sorakake Shoujo. They don't seem to get along at all, Benkei calls her simply by 'woman'. Benkei says that the first thing she has to do is to send a mail.
Also Tsutsuji and Hako-chan back in ep 10, both addresses Aleida by priestess or something.
(seems like Navis could be descendants of Brain Colonies and used to interface with smaller machines instead of colonies and being cyborgs, half robot, half human, does that mean that potato head is actually a brain? We see Ul drinking all the time and they seem to need to eat.)
Leopard is spending the day as 'Leo-niisan', posting on the internets. Sakura gives him a 'ostu no pappa', (falling smash). Leopard rages and Sakura gets her fun, then Leo-niisan recieves new mail.
He reads that its from someone called Tsutsuji who's saying that a red colony called Leopard is a mirror-thief and has stolen mirrors but has no idea how to catch him. Then a link:
http://www.sorakake.net/benkei/, supposedly has some leads. Leopard clicks and sees its a taunt from Benkei and rages, mainly the word 'FOOL' and that Leopard's mirrors will be the 100th of the 99 colonies he stolen mirrors from. Just that Akiha enters the room asking whether Leopard knows who the mirror-thief is, Leopard rages again lol
Buu and Min has been stealing mirrors from the entire ICP to try and lure the mirror thief.
Meanwhile Nami returns home back to being a hikkikomori. It seems that she has reached the criteria of a Nervalist and Aleida uses her QT-mindtricks and brings Nami over. Nami senses her mom in Aleida. And Nami has finally become a true Yandere, using a crowbar to take out the meidos.
And back in space, Itsuki, sent by the ICP to track the ICP Mirror-Thieves, Buu and Min end up in a bigger confrontation of the the true Mirror Thief Benkei and Leopard whom the Shishidous have been using the same plan as a lure.
