Ep. 16: Ayumu and Nagi escape killers while Hayate and Ginka pursue them to Atami

Ayumu and Nagi evade assassins, but Nagi departs, confident Hayate will arrive. She reacts negatively when Ayumu mentions her mother. At an onsen, Hatsuho notes Hayate resembles Nagi’s mother. Hayate locates Ayumu’s phone and is attacked by Ginka, who intends to bring him to the Shimoda onsen. Ayumu returns to Nagi with a drink, but the masked killers reappear, forcing them to flee again. Hayate and Ginka arrive after a confrontation, and Ginka defeats the assassins so the group can reunite at the Atami train station. Nagi instructs Hayate to bike Ayumu further, while Hinagiku watches Nagi and Maria on the train. In Shimoda, Nagi meets Sakuya and visits a secret hot spring that makes her appear intoxicated. This state does not affect Sakuya or Hayate, who retrieves Nagi, causing her embarrassment. Later, an alien crashes into Nagi’s room at night.
