Haraken kept having dreams about Kana. His Aunt, concerned about him, had told him to have a thorough check-up at the hospital. The girls, on the other hand, are busy with other things. Yasako was supposed to start right away on her independent research, but got distracted when she saw Amasawa and her 2 underlings. Amasawa was going to capture another Illegal to complete whatever she’s trying to do. You know, I kind of understand her intentions — saving her brother simply put — but her method is confusing me. Why was she collecting those Illegals again? I mean, inside her body?
Yasako goes to the library to search online about kirabugs and its importance. While reading, she was startled when Haraken greets behind her. They went outside to talk about an obsolete space that she discovered from following Amasawa. Then she tells him about what Amasawa and her talked about in the hospital regarding her brother and the kirabugs. It seems Haraken gets an idea from that, but doesn’t tell it to Yasako. When Yasako was about to confess, as it seems to me, about something, Haraken cuts her off and tells her that they should check the next day the obsolete space. They didn’t get to meet the following day though since Haraken goes ahead of her. He searches frantically for Amasawa. He asks her 2 underlings, but they ran away from him. Things didn’t look too well with Amasawa when Haraken’s Aunt suddenly went to there to erase her encodes. The 2 underlings tried everything to chase the Satchii off. Only to no avail. During this chaos, Haraken finally sees Amasawa. He tells her that he wants to do a trade with her — his offer is that he’ll give her the access code to the Satchii if she will help him get to the other side. Yasako realizes that Haraken might have gone to the obsolete space without her since the obsolete space is near where Kanna died.
Wow, a lot (but nothing too complicated) happened in this episode.
This took me days to figure out how to summarize the episode. It shouldn’t be too hard. I guess this episode wasn’t that interesting for me. The topless Haraken didn’t even make up for it. 
J/k! Anyway, Haraken is still obviously into Kanna. Whether he likes her or not, he believes that she is in danger. He plans on saving her by going to the other side. He must be thinking that if he takes back the what-seemed-like soul of Kanna to their normal world, Kanna would be alive and kicking again.
