In the summer of 2020, Jun defends her friend Misaki Yasojima from accusations that she is one of the Rats responsible for killing certain executives on the island. She later interrogates Ginga Kanashima (who is acting under the alias 'Daichi Tsuchimi') and offers to protect him if he wins a rock-paper-scissors contest. Soon after, she intervenes when Ginga is bearing down upon Nejiro Kanata.
A few months later, Jun is caught up in the events surrounding the explosions on the Artificial Island. She investigates Charlotte and Sherlock Liverpool's involvement in the incidents as well as Yakumo Amagiri, only to voluntarily surrender herself to Lihuang Ei in order to protect the siblings from him.
During the showdown by the massive engine at the heart of the island, Jun is supported by the rest of the Guard Team in her fight against the Chinese Mafia. In the aftermath, she greets her colleague Nazuna Yukimura with tears of joy when she learns that Nazuna is safe and whole.
