-On Day 1, Hokuto wonders where he is. He thinks he remembers where he is, but he can't say the name. Fast forward. When You says they have to escape, Hokuto is confused, but You shouts at him to go and grabs his hand.
-Fast forward. Hokuto asks if they can get out of LeMU on foot, but You confirms no, since the elevators are out of service. Fast forward. Hokuto decides not to ask You if she heard Coco. Fast forward. When Sara looks at Hokuto, he looks back at her.
-He asks if something's wrong, but she's silent. He asks again, and she says, "Huh!? Wh-What?" Hokuto asks if she's okay, and she says she's fine (though her tone is artificial) and asks why he asked her. He says it's because she looks down, but she says that's not the case, just that she was remembering something about the past. He enquires, but she says
Sara: "But now's not the time for that. There's something I've got to do..."
-Sara then leaves the room. Fast forward. I learned that like the original, Kaburaki's dialogue when he's asleep is different each time. This time, I got:
Kaburaki: "... Got a long name... wants to see her parent's face... Zzz." (This was also in the original)
-Fast forward. Hokuto doesn't understand the Archimedes Principle, so You explains it for him. Fast forward to when You and Sara are splitting up. Naturally, I chose to go with Sara this time. When he does, he sees Sara's shoulders sink. He tries to take her hand, but she dodges it, saying "Whoa there! It would be best not to touch my hand, no?" otherwise, it'll ruin her ninjitsu.
-They walk through the halls. Hokuto's heart stirs when he looks at Sara's face, and wonders why he's so concerned with Sara and why he knows her, then thinks he doesn't know about her, and wonders what kind of girl she is. He decides to ask her, but thinks he can't just ask bluntly.
-He asks her how she knows You, and she gives the same answer You did. She says the time she spent with You was the most fun she'd ever had, and that her meeting You, "really saved my heart." She says You was the first and most precious friend she'd ever had.
-He asks why she didn't have friends before that, and she explains she had to keep transferring schools due to her family. When she says that, a sad look rises to her face. Suddenly, Hokuto's head pounds, his vision growing red. Pain runs through his heart, telling him that this is a topic he musn't touch upon.
-He decides to ask her about her ninja hobby, as he doesn't remember what ninjas are. She gives a lecture about the history of ninjas. After she finishes, Hokuto remarks the word of ninjas sounds harsh, and she agrees, another sad look in her face.
-He looks away for a second, and when he looks back, Sara has disappeared. Hokuto starts freaking out, telling her to stop hiding and come out. He runs around looking for her. As he calls her, he hears the rapping of the ceiling from the pipes. He then remembers the rapping phenomenon, and wonders how he knew that.
-Hokuto runs away in fear, and runs into Sara. She asks what's wrong, and he shouts it's the rapping phenomenon. Sara explains it's just caused by the pipes. After Hokuto calms down, he asks why she suddenly disappeared, and she says, "Well? Were you suprised?" She says she used ninpo to hide.
-While they're walking again, Hokuto asks for Sara's age. She says she's 16, was born on January 21st, and is an Aquarius. She asks for Hokuto, but he doesn't know. She says it sounds lonely, but it might be good, since he may have had a past he wants to forget. She then says she's just kidding, and the rest is the same from the original.
(How ironic... the answer was right in front of him... Speaking of which, how does Sara know her birthday? Did Tsugumi leave their birthdate with the orphanage?)
