Veronica is the princess of a country that perished in ancient times. Harusumi Minami, a boy living in the present day, has had memories of Veronica's death since childhood. Harusumi cannot believe the events in his own memory, and when he reveals that the princess is from his previous life, he is shunned by those around him and as a result spends his childhood in solitude. However, in middle school, he realized that the magic Veronica learned in their previous life can be used by him too. Several years later, Harusumi becomes a high school student, and as he adjusts to new relationships, he makes it his daily routine to write down things in his memory in a notebook. When a classmate sees his notebook, Harusumi's fate regarding his past life begins to change.

• Harusumi Minami • Jun Fukuyama (drama CD) • He is the reincarnation of Princess Veronica of Zerestria. He retained his memory as Veronica since he was very young and was ostracized in elementary and middle school for asserting his past life. The only one to believe him was his close friend, Kamioka. His notebook is part of what triggered the others to remember their past selves, along with the use of magic. He and Yuu are the only two known characters to be born of the opposite gender after being reincarnated. • Haruko Takao • Aya Endō (drama CD) • She is Harusumi's girlfriend, one of the first few who came to the realization that Minami is Princess Veronica. She is the reincarnation of Rida Razarasare, Veronica's bodyguard. She often acts as his protector, even in the present time. • Yu Hiroki • A close friend of Takao and middle school friends with Ryuuji and Momoka. At first, she pretended to be Princess Veronica until Minami confessed to his true identity. Later on, she revealed to be reincarnation of Bart Belbania of Zerestria, but was actually using Bart's identify to hide her real identity as Glen. She hid her identity because she fears that those who wished to harm her in the past will come after her again. She has retained her memory of Glen since her first year of middle school. Harusumi and her are the only two known characters to be born of the opposite gender after being reincarnated. • Tatsuya Otomo • He is the reincarnation of Carlo Velbard, the bishop's right-hand man, a priest second-in-command of the church who knew Veronica as a child while she lived in the monastery. In the present, he is currently in charge of the priests because of the bishop's absence. • Saya Kamioka • She is Harusumi's friend from middle school. She was the only person who believed him, the only one that was his friend. In high school, she was placed in a different class from Harusumi. She was attacked by someone with the ability to use magic one day after school, which caused Harusumi to strongly wish and prevent dragging in ordinary people who are not related to the past events. • Ryo Zeze • He is a classmate of Harusumi and a carefree student who gets along with everyone. He is a part-timer at a karaoke owned by his parents, the place which is used by the characters to host their secret meetings. He does not remember who was his past self, not wanting to remember it. It was later revealed through flashbacks and quotes that he is the reincarnation of Prince Eugene.
