Kagari Shiina

Shiina Kagari is the adopted daughter of Shiina Mayuri in 2036 in the Beta 1.129848% World Line. In the year 2028, Mayuri is working at a children's orphanage and given custody of a young girl. Because of the war the girl's family register was lost and her true full name unknown. Over time the child grew to view and love Mayuri as her own mother. Mayuri gave her the name "Kagari" -a reference to "kagaribi（篝火?)", meaning bonfire-, with the wish that Kagari would be a shining light to everyone no matter how dark the world line is.

She was adopted by Mayuri in 2034, and in 2036, she time traveled with Amane Suzuha to the past. However, Suzuha and Kagari became separated in the year 1998, causing Kagari to have grown into a 22 year-old woman by the year 2010.

Kagari figures in Steins;Gate 0  and the light novels and manga adaptations of Epigraph of the Closed Curve, Pandora of Eternal Return and Altair at the Apoapsis of Infinity.

In Steins;Gate 0's Altair & Vega route, Kagari Shiina had plastic surgery to look like Yuki Amane. It was revealed that the original Yuki Amane is safe and is studying in Europe.

She has lost her memory, due to amnesia, which may have been caused by time traveling with Amane Suzuha.
