Jun is a disorganised, ditzy office lady who secretly works as Blood Falcon, an agent of Shooting Star. Unhappy with her job and struggling with aggressive older men at work, her chance meeting with Shooting Star helps unlock her potential. Inspired by his belief in her, Jun begins opposing the Anima Mundi.

After losing Shooting Star, Jun, Miyama and Hatoko stop supporting Rosenkreuz and form a new group, “Akihabara Dendō Shibire-gumi,” to protect Akihabara and honour his legacy. By the 2011-nen no Natsuyasumi film, Jun has fully abandoned her villainous past and now works hard to support the Anima Mundi.

In battle, Jun summons the Avatar Cerberus. Although Cerberus isn’t a particularly strong nanocreature, she uses it eagerly, often in violent battles against the girls. When Shooting Star grants her the power of an Apostle (false Diva), she uses the machine called Astaroth.

Though not refined, Jun has a stereotypical noblewoman’s laugh (“ohoho”). A recurring gag in the series is her laughing, causing her large breasts to bounce in an exaggerated manner.

Jun is named for Gōtokuji Station in Setagaya, Tokyo.
