-Day 6.
-Plays out the same until Takeshi meets Coco in the hall. He thinks Sora knew from the beginning that she couldn't be saved, and that she wants to be saved. When she asks him his dream, Takeshi said he dreamt of a woman he couldn't touch that he wants to save, but couldn't find the method to do so.
-Coco's "method" starts, the same, but in the middle:
Coco: "... I can see... I can see you... Everyone can see you too... so you just haven't been found yet. I'll open my eyes properly and find you... because... I can see you... (strange SFX noises) I can see! I can see! I can see too! (more strange SFX noises).
-Rest is the same, except the topic is Sora. The rest stays the same until Takeshi goes to do checks on the sub. Once again, his mind turns to how he can possibly save Sora. He goes to find You about saving Sora.
-When they get to the mysterious translated lines in the ruins, You talks about how wakas can have messages hidden in them, and wonders if it could be about the hidden "treasure" of Lemuria. Takeshi tries to bring up the Sora issue, but You blissfully ignores him until he shouts. He tells her that Sora's main computer is in LeMU, and as she's about to speak...
-Kaburaki comes up to them, informing them about the fight. Unlike the original, Sora is not denying the existence of IBF, but is saying it's too dangerous to go down. Tsugumi says she's lying, trying to keep them from going down.
-Sora replies she's just thinking of everyone's safety, and she doesn't want to lead them into a dangerous situation. The rest plays out the same, except that because You's with them, she says a bit more. Sora also says:
Sora: "Coco-chan, it can't be that this is... no, that's impossible..."
-When they get there, You sets up the scanner. When they scan Coco, they get "Unknown Virus" again, but this time, Sora tells them about Tief Blau, but says she doesn't know if it can be cured. All that's in her database is that it's a deadly virus.
-Takeshi asks if the current sub's charge would be enough to get to the surface, but Sora says no, and normal hospitals wouldn't know of TB anyway. After Takeshi cries, Sora announces there is one way to save Coco. She tells them of IBF, and informs them it's a biohazard right now. Takeshi is shocked, and realizes TB leaked out of IBF.
-Tsugumi says if that weren't the case, none of this would have happened, since they were studying and making TB down there, otherwise it would be known about on the surface. Sora informs them IBF was being used to make bioweapons. Sora pretty much then tells Takeshi everything Tsugumi told him in the sub bay in IBF on her route, but expands on some areas while remaining in the grey on others.
-Takeshi realizes the incident with Sora yesterday must have resulted from IBF's networks, which are connected to the LEMMIH series on the surface, but Sora insists the IBF computers can only send and receive data (I think- again, too much techno talk that I don't understand).
-You realizes there must be a cure for TB down there, since you don't make a bioweapon without making a cure for it first.
-When Takeshi tries to go alone, the others insist. He tries to say no, since it's a biohazard. You says the reason the rescue team didn't come is because it's a biohazard, and they'll need to go anyway.
-Sora tries to tell them not to go, but Takeshi says they must save Coco. Sora says she wasn't trying to stop them, but tell them to be careful, since she can't join them. They take Coco and go.
