Tachikawa, Satoka

太刀川里香

Tachikawa makes her debut in the third episode, rescuing Miu and her friends during an Invader attack on a Karaoke Bar. Her combat style typically involves frontal assaults, using her gate to materialize various swords and knives.
Reiji Kageyama summons her to the region as reinforcements for Ayane Isuzu, the Top-Ranked hunter. In contrast to Ayane, Tachikawa performs her duties with zeal and appears to enjoy earning money from her missions. Their personality clash fuels the one-sided rivalry she holds against Ayane. Ayane generally ignores her, walking away even mid-conversation. This dismissive behavior only serves to frustrate Satoka further.
