Yuki Amane

Yuki Amane (阿万音 由季) is a friend and fellow cosplayer of Mayuri Shiina. She is Itaru Hashida's future wife and the mother of Suzuha Amane.

Appearance
Yuki has long brown hair and blue eyes.

She is rarely seen outside of her cosplay outfits.

Personality
Yuki is a cheerful and optimistic woman who is tolerant of Daru's perverted jokes. That being said, she hates it when Suzuha says "moe" or other such things. She loves Daru even after he died in the future. Determined and understanding, she kept her husband Barrel Titor's real name from being known by Suzuha to ensure her mission's success.

Background
She is a senior at Meiji University and part of the same club as Kaede Kurushima. At one point, she gave up cosplaying and attempted to job hunt, however, she gave up on working after 6 months and returned to cosplaying.

She first met both Mayuri and Daru at Summer ComiMa. In the Linear Bounded Phenogram, she was cosplaying as Chopstick Girl, a Rainet character, when she accidentally bumped into Daru.

In the manga Boukan no Rebellion, she was the one who introduced 'moe' culture and cosplay to Suzuha in the year 2035, thus making Suzuha excited to go to Comima in the past. She was killed by Kayano while working on a maid cosplay outfit, which she intended to show Suzuha before she carried out her time travelling mission.

Beta Worldline
Yuki appears regularly as a side character throughout Steins;Gate 0. On a few occasions, Okabe suspects her to be the woman in black who attacks the lab, but she is later vindicated.

Recursive Mother Goose
Yuki is on a date with Daru that is interrupted by Okabe, Mayuri, & Kagari who wished to ask her the origin of a song. She reveals that she learned it in cooking class from a woman who turns out to be Okabe's mother.

X-Day Protocol
Yuki helps set up for the Christmas party. When everyone tries to surprise Suzuha, she instinctively attacks Yuki, but manages to stop herself before injuring her.

Pandora's Box
After entering the new Worldline where WWIII had already begun, Yuki and Fubuki meet up with Okabe on his way to Okinawa. Shimoyama asks her is she knew the location of Daru and Suzuha, which she denies, though Okabe suspects that she could be lying. Yuki is left confused as Shimoyama asks Fubuki and Okabe questions regarding their memories.

Vega & Altair
In Steins;Gate 0's Vega & Altair route, Kagari Shiina had plastic surgery to look like Yuki and had been taking her place since meeting Mayuri and Daru. It was revealed that the original Yuki is safe and is studying in Europe. This only seems to be the case in the Vega & Altair route though.

Egoistic Poriomania
Okabe briefly sees Yuki when at the convention and, mistaking her for Suzuha, follows her. He eventually catches up to her at a dinner and apologizes for the misunderstanding. The two go on to talk with Yuki revealing that a psychic told her that she would have a child in 7 years, implying the child to be Suzuha. She later catches a cab and leaves, unintentionally leaving Okabe stranded.

Load Region of Déjà vu
She is briefly mentioned to be dating Daru online, though the two haven't in person yet.
