Satoka Tachikawa is a bounty hunter type Gatekeeper.

Introduction[edit | edit source]

Satoka first appeared before Miu Manazuru after rescuing and her friends Chinami Watanabe and Naoko Ito when an Invader attacked at the Karaoke Bar they were in. Her combat tactics generally revolve around frontal assaults using her Gate to materialize a variety of swords and knives.

Background[edit | edit source]

Satoka was Summoned to the region of Tokyo by Reiji Kageyama, she arrived as reinforcements for the Top-Ranked Invader Hunter, Ayane Isuzu.

Unlike Ayane, Satoka does her job with zeal and seemed to relish making money from her ventures. The differences in their personalities also fueled the one sided rivalry that Satoka started with Ayane when she arrived. Ayane generally tried to ignore Satoka and would often walk away even during the middle of conversations. This dismissive attitude only served to frustrate Satoka even more. However Satoka does have a softer side, when she had to kill Miu's friends Chinami and Naoko she did not take the gems left behind.

Satoka fought alongside Reiji to help Ayane and Miu face the Ghost Girl. During the battle she tried to protect Reiji when he became to weak to fight. After the battle was over due to Ghost Girl using her Minus-Gate of Rebirth, Satoka openly wondered whether or not she actually knew what she was doing.
