Identity and life
Serious and timid, at first unfamiliar with the school's special training. As students live together, they need to assess their own teaching and care responsibilities.
Character relationships
The large-scale deployment in Volume 7 forces her to consider whether to let students join the fight. Her given name is written as Autumn Sakura, pronounced Shiori.
Gray Phantom Trigger in Volume 1
New teachers who lack prior knowledge of special training content are overly serious and inflexible, which can easily lead to minor misfortunes. Her ordinary life experience became a different stance from the operatives within the Mihama team.
Volume 5.5: Post-employment evaluation
About three months after arriving in Mihama, Arisaka received a strict evaluation: being serious and enthusiastic was still not enough to handle the work here. She visits the academy, talks with girls undergoing action training, and reconsiders her choice of role.
Volume 8: Follow-up in Mutually Exclusive Branches
In the Annihilation branch, Arisaka lost his original students and later accepted new students. The TRUE branch allowed Tonghua and Megumi to avoid the initial death, allowing the other team members to survive in a chain of events.
Volume 3
During the training camp, Arisaka searched for the escaped chicken while the battle was still ongoing.
Volume 8
Whether Arisaka helps reload ammunition becomes an option. Among the branches she helped, Tonghua avoided the first death in the Annihilation branch.
In the follow-up to the Annihilation Branch, after Arisaka accepts new students, she sheds tears during the group photo scene.
