The last episode starts off with Chii touching Hideki's face. She asks him "Are you the one for me?" Hideki stutters for a bit, and then Chii starts making that super bright light again (his window explodes). Then he says something close to "I'm in love with you Chii", and then they embrace. Chii has finally found the one for her, and only her. Then she gets all wide-eyed and stops talking. She then flys out the window onto the roof. The weird girl in black jumps up there and plugs a cable into Chii's head. She says she is going to destroy her. Hideki freaks out and starts to climb up to her, but the guy in black restrains him. After he explains himself, the guy in black lets go of him, and leaps up and unplugs the cord. He says he wants to see what happens. A ball of light encircles Chii, and then vanishes after a short time. Chii then says that she is no longer Chii, but her sisiter Freya. The apartment manager (sorry forgot her name) rushes out and "greets" her long lost daughter. Freya then explains that when she ways dying, Chii plugged her cord into Freya's head and downloaded her. Freya tells her mother that it is time to delete her and Chii forever. Her mother doesn't say anything at first, but then she states the password and says "Deletion of all data and termination of the system" Hideki of course is yelling at her to stop. The manager says "Initiate" and Freya goes wide-eyed. A few moments later she says "Deletion complete". Hideki starts giving a heart-felt speech to Chii, even though she doesn't exsist anymore. The persacom stops moving, and her mother asks "What's wrong?". Chii starts crying and by some miracle, she is still Chii even though she was supposed to be deleted. She runs forward and embraces Hideki. Chii then says to Hideki "Chii is a persacom. There are things that Chii cannot do that people can" and Hideki says "I know" and she says she wants to be together with Hideki. It then shows them in his apartment with Chii's voice-over playing in the background. Everything she says basically sums up to "And they lived happily ever after." When I started watching this, I thought for sure in the end that they would pull a fast one and kill her, but I guess I was wrong.
