Similar to Kotonoha, Rena also has a Multiple Persona that changes her personality that only to be awaken by Simon Belier. As Juri, she is sadistic, ruthless and even possessing murderous intent similar to Mortio's Yasen persona.


Rena was born as a daughter of Mieko Matsui, a woman who possessed a supernatural power named Super Tuning that allowed her to syncing with one person and read that person's heart and even "residential thoughts". When Mieko's powers was awaken and escaped, Rena and Mieko became terrorist targets and often on the run. When they sought shelter at the Japanese Embassy, Rena met Morito as the Matsui Family's guardian and despite she initially views him as a "child", she eventually impressed by his prowess as he has protected the Matsuis.

Unfortunately, that happiness was short-lived as Mieko died one year later in an unknown circumstances. When Rena demanded answers from Morito, he did not reply but blamed himself for lacking his strength to protect her. Despite this brew Juri's hatred against Morito and blamed him for Mieko's death, Rena still loved him as her father and vowed to protect him from harm.

Several hours later in Morito's room where all four were still stunned by the revelation, Rena explained her goal in the Mikado Academy not only support Morito but also challenging anyone to be Morito's next "wife". However, the competition itself was no easy task as Rena explained that candidate had to be faithful, intelligent and powerful enough to join Hayama Family because of its involvement in dangerous mission, especially the hostage situation; moreover, she adds that that the candidate have to be ast stronger than herself to be qualified and claims that whoever win the competition would be Morito's future wife (and her future "mother"). Rena's words has fired nearly all four protege's souls including Futaba who as eavesdropping outside the room, further Morito's dismay. During her bathe with her father, Rena reminded Morito to realize others and his own feelings, before she slept with him in his futon as parent and child.
