Yui Mabuchi

is a female school teacher who is searching for Ryuga Banjo in Build NEW WORLD: Kamen Rider Cross-Z, after being transformed into in the original World of Build.
==History==
===Background===
In the original World of Build, Yui Mabuchi was once a kindergarten teacher who was caught in the crossfire of the Japanese Civil War. Nearby, they spotted Kamen Rider Cross-Z and begged for his help, but he disregarded their pleas, which caused the Guardians to capture her and her students. Yui was subjected to Faust's Nebula Gas experiements and forcibly transformed into the Scissors Lost Smash. She was then chained and mercilessly beaten by the Guardians, who then after severing her connection to the Lost Bottle, watched as Yui spontaneously combusted into nothing.
===Build NEW WORLD: Kamen Rider Cross-Z===
Yui Mabuchi was given a second chance of life in the New World but had no memory of her life, except one thing, Kamen Rider Cross-Z. As Killbus emerged from the Pandora Box and revived Evolto, her memory was returned, alongside all those who had been subjected to Faust’s Nebula Gas experiments. Because of that, Yui initially bore a hatred towards Banjo and the Kamen Riders. However, Yui continued to accompany Banjo in his attempts to stop Killbus. She would learn of his past, the burdens he had to bear, and his connection with Evolto. 
As time passed, she grew fond of Banjo and also learned more about him from Misora and Sento. In the last battle against Killbus, Yui was told by Sento to give him Muscle Galaxy Fullbottle. As Banjo failed to use it at first, Evolto pretends to betray them and choked Yui to provoke Banjo into raising his Hazard Level. After the battle had been finished, Yui bluntly kissed Banjo on the cheek in front of Gentoku and Kazumi, much to their jealousy. The next day, she went on helping Banjo sell Sento’s inventions by appealing to the children.
