-He closes his eyes, and remembers his friend's faces. When he gets to You, he remembers You begging him to save her and his promise to her. Hokuto screams again, curses, cries, and kicks the walls. He falls to the floor in pain. He realizes the pain is proof he exists. He stands up, and sees Coco in front of him.
Coco: "... I can see... I can see you... Everyone can see you too... so they just haven't been found yet. Open your eyes properly and find them... because... they can see you... Right... open your eyes... so find them... because... I'm waiting... they're waiting... So for now... goodbye..."
-Coco disappears into HIMMEL. Hokuto can now see the door. Regaining his resolve, he swears he has to find them. He closes his eyes, and believes he'll find them. He then thinks, "If you wish and believe, that wish will become reality..."
-He opens his eyes, and is engulfed by light. He then says he can "see" a seven colored light. He reaches for it, and the light becomes You. We have a new (fairly lazy) CG of You at the end of this strange blue light tunnel, hugging her knees, with Hokuto reaching for her (we only see his arm).
(Yeah... I have no clue either... Evangelion made more sense than this...)
-He shouts You's name, and she goes "Kid? Why are you here?" He says he's fulfilling his promise. She reaches out for him, and Hokuto uses all his strength to stretch. But he can't reach You.
(I got a Quick Save here, so I assume this is where it splits between the Good End and Bad End)
-You says she can't reach him. Hokuto tells her not to give up. Their hands grow closer, but they can't reach each other. He keeps missing, and remembers it's like the time he tried to cap the pen. He compares the light to a dragon blocking his way to You.
-You says "Guess it's not good after all..." Hokuto keeps shouting not to give up. You still has no hope, and Hokuto tells her to look at his eyes. He stares at hers, and tells her to try laughing. She's confused, and he reminds her of what she told everyone at the Cosmic Whale.
-She smiles and laughs. Hokuto keeps stretching, thinking his feelings are limitless, so he'll definitely reach You. At that instant, we get a new CG of their hands, mere fingertips away from each other. Hokuto grabs her hand, and pulls her towards him. They embrace and kiss each other.
-The light shines white and You says "I am You. You are me. We're not alone." New CG of a smiling, crying You, with her head besides Hokuto's, her arm wrapped around his neck. They're in the Lemurian Ruins. Hokuto thinks about how the whole group is linked together by invisible bonds.
(Funny... we see Hokuto's hair, but it's dark colored to the point it looks brown... then again, keep in mind his hair looked pretty dark as well during the "15 Year Reunion" CG, which was in a dark room, as is the Lemurian Ruins.)
-He goes to check on the others, and returns to the Control Room. At first, there's only 2 life reactions, but the number climbs back up to 8. Sora reappears, and asks if they're okay. You says yes, and asks about the others. Sora says they're all waiting in HIMMEL.
-You says they're going there to ask her Mom some questions. Sora guides them to HIMMEL. They open the door, and we're greeted by a new CG- a sillouted You"haru".
-End credits. Life reactions still alternate between 0, 1, 2.
(So... anyone wanna guess what the hell just happened?)
