|Age||0 (physically mid-20's, based on Rosemary)|
An artificial intelligence programmed by Rosemary. Based on Rosemary herself, sharing her intelligence and cruelty. Her sole purpose in existence is to serve Rosemary. Contacted by Rosemary in Midori Arc 2: Haywired Homeshield. Used the alias 'S' in the communiques. Introduced the evil virus to Homeshield to serve as a distraction so she could access valuable Mato files and send them to Rosemary.
Sakura enjoyed causing chaos around the Mato house, especially for Jake. She made it look like Jake infected Midori's laptop with Findows 98, emailed the contents of his web browser to the girls, and, perhaps most evilly, caused a power surge that destroyed all his saved games.
Confronted Jake and company in the cyber world, badly wounding CAP. Afterwards confronted Jake in a completely original battle disc fight, where she was mortally wounded. Shortly thereafter revived and enlarged by BUD, letting her almost kill Jake. Destroyed when antivirus program was delivered to BUD.
Though Sakura failed to send the files Rosemary was after, she did send one file that showed Mato obtaining stock information from the future from an entranced Lucia, along with enough information to reconstruct her should Rosemary choose to.
