Wakaba Isshiki is a character in Persona 5.
- Persona 5: Supporting Character, Boss
Wakaba Isshiki was Futaba Sakura's mother and a prominent cognitive scientist. Futaba thought she was a benevolent mother even when the former had a fit during Wakaba's busiest time in her research, until Wakaba died in what appeared to be a traffic accident, but in reality was killed by Masayoshi Shido. Out of spite, he forged Wakaba's will, in which he claimed she regretted giving birth to Futaba. This revelation devastated Futaba and caused her to develop paranoid delusions of Wakaba's face overlaid on other people, constantly telling her how disappointed she was, which eventually drove her to become a shut-in with suicidal impulses. Later when Futaba enters her own Palace, her shadow convinces her that the testament is a fake, resulting in Futaba's awakening to her Persona ability. Futaba helps the Phantom Thieves of Hearts defeat the false perception of her mother which takes the form of a gigantic and spiteful Sphinx. After the battle, the image of a benevolent Wakaba appears before Futaba and confesses her love for her daughter then disappears.
Wakaba's death, false testament and the stealing of her research are revealed to be Masayoshi Shido's doing for eliminating his enemies in an unconventional way.
"Cognitive Wakaba Isshiki" (認知存在『イッシキワカバ』?) is formed from Futaba's false belief that her mother resented her for being an obstacle to her career. It takes the form of a Sphinx in keeping with the Egyptian theme of the Futaba Palace. The battle is fought in two rounds.
