An outstanding mage serving as the seventh of the Ten Sages, and the head of the "Kisaragi Family" during the Dark War. An intelligent, glasses-wearing young man.
Seven was the head of the Magister's City of Ishana's Kisaragi family. He was accepted into the Ten Sages at a relatively early age, becoming associates with Eight. At some point, he and Eight began working on the Gigant: Take-Mikazuchi, a weapon that could repel the Black Beast and end the Dark War. Nine built the foundations of the weapon, while both Seven and Eight continued its development.
Seven was one of the Ten Sages who were ordered to help patch the barrier in the Magister's City of Ishana in 2106.He, alongside his fellow Sages fulfilled this duty. Earlier that same month, he bore witness to the acceptance of Nine into the Sage's ranks.
Seven, alongside Eight, stood in the Mage's Guild a year after Nine's acceptance. The two of them scorned Nine for bringing Jubei, Valkenhayn R. Hellsing, Yuuki Terumi, and Hakumen into the hallowed halls. Celica A. Mercury, who was also present, attempted to leave but Seven grabbed her arm, demanding that she stay with Nine for the conversation. The uninvited guests, as well as Trinity Glassfille, eventually left, leaving Seven and Eight with Nine and Celica. They asked the younger sister if she would cooperate with a device that could stop the Beast, but Nine abruptly stopped them, her glare alone making the two Sages wince. They both attempted to persuade Nine and Celica, but the older of the sisters was not willing to listen and dragged Celica away from them. She demanded that they both dismantle Take-Mikazuchi as soon as possible.
Left together in the courtyard, the two Sages began to mull over their options. Seven remained adamant in his decision to want Celica to keep the monster from going berserk. The two were then met by Kazuma Kval who acted under the guise of Terumi.
Together with Eight, Seven found Celica at a junction near Ishana's shopping district. They asked for a moment of her time and Seven bluntly asked that she cooperate with their research before capturing a glimpse of the girl's guardian - the Deus Machina: Nirvana. Celica refused, telling them that she knew she would die if she cooperated. Still, they were refused and the girl bounded cheerfully away. From a nearby alley, Seven ordered several figures from the Orbis Librarius Norma to monitor Celica, remarking that she was the girl in Shuichiro Ayatsuki's research. Eight went to leave, and as she was out of earshot, Seven remarked on her disdainful personality.
Both Seven and Eight were part of the battalion that were sent to Eastern Europe in the hopes of meeting and defeating the Black Beast. Together, they teleported Take-Mikazuchi to the battlefield, using Celica's sorcery to keep the monster from going berserk after teleporting her to their location. They swiftly left after the weapon did enough damage to cause the Beast to flee. It was humanity's first victory, but Celica was sent unconscious by their decision to use her power without her consent.
Both Seven and Eight came back to the Ishana Cathedral after having witnessed the retreat of the Black Beast. Seven reminded Eight to not be so loud in her celebrations but struggled to hide his glee at such a success. Their happiness was short-lived as Kazuma appeared in the shadows - Seven listened to his praises yet both Sages remained on guard whenever the man appeared in front of them. A short time later, both Seven and Eight had received orders from the Committee of Hearing to detain Nine and bring her to them. They apprehended her with binding sorcery from other mages under their command, separating her from the other Six Heroes in the Cathedral.
