Myna Yatomika, designated March Hare, held the role of Processor within the Third Platoon of the Spearhead Squadron, operating under Captain Theoto Rikka’s command. Transferred to the squadron on April 1st RY 367, her duties encompassed administrative tasks like updating personnel records and attending ceremonial events such as the squadron’s cherry blossom formation party. Combat engagements against the Legion marked her service, including critical operations on May 22nd and June 15th that resulted in the deaths of squadmates Kujo and Kaie.

Known for her sharp wit, she playfully teased Kurena Kukumila over her infatuation with Shinei Nouzen while forging strong camaraderie with Lecca Lin and Mikuri Cairo. The trio frequently gathered for recreational activities like darts, their bond deepening after losses such as Lecca and Daiya. Myna openly doubted Vladilena Milizé’s capacity to withstand frontline realities as their Handler, challenging her sheltered upbringing.

Her survival instincts mirrored the squadron’s fatalistic reliance on Shinei’s leadership amid inevitable mortality. Active in combat until August 15th, she perished alongside Mikuri and Shuri during a mission, marking the ninth to eleventh fatalities in Spearhead. The Aristea flower and her *Alice in Wonderland*-inspired callsign—evoking erratic energy—mirrored her narrative function as an unpredictable yet integral squadron element.
