Tsuchinaga Hiyori — Blue Archive

Hiyori, Saori, and Misaki survive a childhood of poverty around Arius, scraping by and stealing necessities. Saori becomes their organizer and protector. They later meet Atsuko, the girl they call Hime; Hiyori is struck by her elegance before understanding the danger surrounding her. Saori eventually trains Hiyori, Misaki, Atsuko, and Azusa as the group becomes Arius Squad.

Beatrice teaches the children to regard suffering, hatred, and obedience as inevitable. Hiyori later tells Sensei that Arius students were taught to view Trinity as the source of their hardship and to believe that outsiders would never accept them. Her bleak expectations are thus connected to a specific coercive upbringing, not simply a comic quirk.

The squad’s involvement in the Eden Treaty crisis ends disastrously. When Beatrice turns against them and takes Atsuko for a ritual, Saori is separated from Hiyori and Misaki. During the reunion with Saori and Sensei, Hiyori first assumes she is about to be captured and punished. She then reveals that Beatrice’s side offered to let her return to Arius if she disclosed Saori’s location.

Although she is terrified, Hiyori rejects the offer. She cannot abandon Saori or Atsuko to save herself. This decision is one of her clearest moments of personal courage: her loyalty is not the absence of fear but a choice made in spite of it. She rejoins the attempt to rescue Atsuko alongside Sensei, Saori, and Misaki.

Hiyori continues with the rescue through the conflict at the Arius basilica. After the confrontation with Beatrice, Atsuko is recovered and the squad must face the consequences of its past rather than simply return to its old assignments. Sensei’s insistence that these students deserve a chance to live challenges the lessons they learned under Beatrice.

At the close of the Eden Treaty arc, the group faces an unfamiliar road. Hiyori is frightened by the uncertainty, then panics when she notices that Saori has departed on her own. Misaki and Atsuko remain with her; the squad’s immediate future is unsettled, but they are no longer bound to Beatrice’s orders.

In Volume 6, Arius Squad becomes involved in efforts concerning its school while Hiyori also gets a glimpse of unfamiliar comforts. At a meal Nagisa arranges aboard a docked cruise ship, Hiyori is overwhelmed by new flavors and asks about taking some food away. While drinking tea, she remembers that the old Arius training system sometimes rewarded students with a cup of warm water. The contrast exposes how little comfort had been available in her earlier life.

Her behavior during the return to Arius shows both familiar nerves and growing concern for others. When Misaki speaks figuratively about her skin prickling at a hostile reception, Hiyori instinctively offers lotion, a small but revealing instance of her literal-minded attentiveness. Even after repeated setbacks, she can answer the squad’s grim circumstances with unexpectedly wry humor.

Near the end of Volume 6, Atsuko announces that Arius Squad will act as the school’s student council until a proper election can be held. Atsuko takes the acting presidency; Saori becomes vice president and general manager; Misaki takes the treasury; and Hiyori is assigned the position of secretary and record keeper. Atsuko says Hiyori cried on hearing of her responsibility, then resolved to work hard at it.

Hiyori also participates in the school’s new academic direction. At the subsequent mock-exam results, she is distressed to receive rank four, then discovers Maia received the same rank; they celebrate being “rank four buddies” and decide to try harder next time. This modest scene neatly captures her later trajectory: still easily discouraged, yet increasingly able to turn disappointment into shared determination.
