Vivio has a sparring match against one of the other tournament combatants, Chantez Apinion, using Chris' Contact Mode to block each of her attacks but becoming caught off guard by Chantez's special technique. Meanwhile, Hayate and her team finish completion on Einhart's new device, which she decides to call Asteon or Teo for short. Afterwards, each of the girls begin their individual training for the tournament, with Vivio studying under Nove, while Chris approaches Nanoha on how better to protect Vivio. As the day of the tournament qualifiers soon arrive, Vivio is introduced to Vita and Zafira's understudy, Miura Rinaldi, with both of them clearing their qualification rounds.
