The Zero girl Sacrifice takes Ritsuka out to lunch and Ritsuka finds out that Zeroes aren't artificially made people; they're actually humans whose ability to feel pain has been blocked from the receptors in their brains. That evening, the Zero girls, Soubi, and Ritsuka fight, and Soubi easily defeats the Zero girls. Ritsuka stops Soubi from delivering the final blow, and the Zero girls decide to forfeit the battle. They decide to stop being Fighter and Sacrifice and be reborn.
