Following a failed startup trial, tension arises between Ichigo and Hiro, leading Hiro to contemplate partnering with the enigmatic Zero Two once more.

The remaining teams proceed, only to find themselves ambushed by a swarm of Klaxosaurs, forcing them into a precarious retreat. Observing the dire situation, Zero Two expresses a desire to assist in Strelizia but faces restrictions due to Hiro's unofficial status as her partner.

However, upon their return, Mitsuru is found severely injured—a stark consequence of piloting with Zero Two—reinforcing her assertion that Hiro is uniquely compatible with her.
