Story 3: Vermilion Sooteer (Kurisu)Edit

Story 4:  Ghosting Rendezvous (Suzuha)Edit

Ghosting Rendezvous01

Suzuha wake up, and see two other version of herself.

Takes place in α0.337337%. Depicts how Suzuha in the alpha world line gets support from two other Suzuhas from a different attractor field world line. The background of the story is very similar to the α0.337187% world line of the original story which takes place after Okabe stops Suzuha from leaving. After discovering the time machine had broken, Suzuha hesitates over her priorities between her mission and friendship resulting in seeing two ghosting figments of herself from the Beta attractor field world line and an unknown peaceful world line. Later they refer to each other as Alpha, Beta and Omega. Despite their presence, only Alpha Suzuha can prove Beta's and Omega's existence. To other people, they are unable to be seen nor heard, but can see their interaction with the environment. They are treated as ghosts by people around Alpha.

The Beta Suzuha from the Beta attractor field wears a military outfit and feels crisp and serious from Alpha Suzuha's perspective. The Omega version of Suzuha, who wears a maid outfit, is a spoiled kid living a peaceful life with no knowledge of time travel. The world line where Omega Suzuha comes from isn't mentioned in the story.

Suzuha learns early on from Omega that Daru is her father. Since Beta has more experience in fixing the time machine, she was in charge of fixing it. When she finds out that Alpha Suzuha's Time Machine can only travel back to the past, Beta tells Alpha that she should go spend more time with dad instead of fixing the time machine. She sends Alpha to shop for replacement parts with Daru. Later, Daru helps Beta with the repairing, although they are unable to speak to communicate directly, so Beta and Daru exchange Mails.

While Daru is helping Beta fix the time machine Alpha Suzuha goes back to her part-time job. When Alpha Suzuha talks to Yuugo, she is accidentally told about the fate of her future and that Suzu Hashida (Alpha Suzuha) had already passed away. She decides not to ask about how she dies. After she finishes her part-time job she meets Kurisu. During their conversation, she finds out that Kurisu isn't the evil person she imagined before traveling to 2010. They also discover their similarity in the sense that both of their fathers had devoted most of their life to time machines/travel.
Ghosting Rendezvous02

Suzuha hang out with Daru.

The next morning, Alpha Suzuha comes to check the time machine repairing progress. Beta apologizes to Alpha Suzuha for Daru accidentally finding out that that time machine can only travel back to the past. Alpha Suzuha then asks Daru to show her around the city. While Daru is resting in the laboratory, Omega tells Alpha that it is like a date in some way, and suggests she should change her outfit to something cuter for this special occasion. Alpha Suzuha and Daru have a great time while they spend their afternoon together. At the end of their "date" Daru reminds himself of the time machine, and the fact that Suzuha will never be able to come back if she travels back to 1975. This leads to an emotional conversation. Alpha Suzuha finally understands her father isn't the emotionless and rational person she had always imagined him to be, but someone with human emotions just like herself. The reason why her dad locked himself up and didn't meet with Suzuha in the future, is not only because it's the only way he can finish the time machine without being discovered by SERN and fail to give humanity its last hope, but also because he already knows that his daughter will meet with him again in the year 2010. Alpha Suzuha then lies to Daru, and tells him that the grown up version of her might be still alive, and this is merely a small departure, but Daru doesn't look convinced.

On their way back, Kurisu shows up. Alpha Suzuha thanks Kurisu for her effort to make sure nothing inappropriate happens between her and Daru. Kurisu then figures out that Suzuha leaves that night and that she won't be able to come back afterward. Suzuha is surprised that Kurisu truly cares about her. She regrets both, not having noticed that earlier and her original impression of Kurisu. She than repeated the same lie to Kurisu that this is just a small departure.

When the night falls, Alpha Suzuha comes to the time machine with the other two versions of herself. After finishing the final checkup of the time machine, Beta Suzuha suddenly suggests maybe she can go to the past instead, so Alpha Suzuha can stay here with dad. Alpha Suzuha feels happy for Beta Suzuha to make such a gesture, but she declines, saying that she is going to the past for herself. When the two ghosting figments become increasingly unstable she finds out that both Beta and Omega are worrying about her. She realized even though these three version of herself look and act different from the outside, deep inside their hearts they are all still Amane Suzuha. When the two ghosting figures begin fading, Alpha Suzuha thanks Omega for her suggestion for the outfit, so she could hear dad say she was cute. She also says to Omega that both she and Beta are trying hard so we can reach you. (which strongly implied that Omega is from "The Steins Gate" world line where the True End of the main plot occurs.) She realized the existence of Omega mean there is a peaceful world line out there thus their goal actually exists, and she is their hope. For her final request, Alpha Suzuha asks Omega, "Don't trouble Mom and Dad too much OK?", and tells her she is counting on her. After both of the figures fade and Suzuha thanks the Beta for fixing the time machine, She goes inside the time machine and activates it.
Ghosting Rendezvous03
Suzuha finds herself in bed, and hears her mother telling her to wake up. Usually she would try to stay in bed for as long as possible, but this time she doesn't feel like it. The words "Don't trouble Mom and Dad too much OK?" were still in her mind. Thus she decides to get out of bed. Her mother is surprised and happy that Suzuha woke up by herself. Suzuha decides for the first time to offer washing the dishes after she finished breakfast to the delight of her mother.
