Blue Archive Story: Reading Order and Kivotos Guide

Prologue: Arriving in Kivotos as Sensei

Kivotos is a city where students run the government and carry firearms as casually as phones. The Blue Archive story begins with the disappearance of the General Student Council President and your arrival as Sensei, the adult asked to help restore order. Follow the chapter requirements carefully: later installments return to earlier volumes, so reading every numbered volume straight through can lead you into a locked chapter.

Your home base is Schale, an independent investigation club established by the missing president. Its authority extends across academy boundaries, allowing Sensei to help students from different schools rather than serve a single campus.

That distinction drives the story. You lead students in combat, but your responsibility also includes listening to their problems and helping them make decisions.

Keep these features of Kivotos in mind:

• Academies govern their own districts. Student councils handle local leadership, while different organizations enforce order.
• School cultures shape conflicts. Trinity emphasizes order and etiquette, Gehenna embraces freedom and chaos, and Millennium values science and technical achievement.
• Weapons are ordinary; students are unusually resilient. Halos accompany their extraordinary durability, but students still experience pain and serious danger.
• Personal relationships matter. MomoTalk and relationship episodes explore individual students beyond their roles in larger conflicts.

Start with the prologue, then move into Abydos. Its smaller cast gives you a manageable introduction to a city with thousands of academies.

Volumes 1–2: Abydos and Millennium

Volume 1: Foreclosure Task Force

Abydos High School is struggling with desertification, crushing debt, and the threat of closure. Only five students remain, making the opening conflict immediately personal: saving the school means protecting the place they refuse to abandon.

1. Begin Chapter 1: Strange Days for the Task Force.
2. Continue through Chapter 2: Things Lost and Others Held On To.
3. Leave Chapter 3: Traces of a Dream for after Volume F.

That last step matters. Volume 1’s third chapter requires completing “Afterword 2” in Volume F, Chapter 4, Episode 12. Its position under Volume 1 does not make it part of an uninterrupted opening read.

Volume 2: Clockwork Flower Pavane

Millennium shifts the focus to the Game Development Department and a discovery in the school’s ruins. Its technology-centered setting gives this arc a different flavor from Abydos’s struggle to survive.

1. Finish “The Masked Swimsuit Gang! Part 2”, Volume 1, Chapter 1, Episode 14, to unlock Volume 2’s opening.
2. Read Chapter 1: Retromania.
3. Complete Chapter 2: The Romance of Friendship, Courage, and Light before entering Volume F.

Volume 3 becomes accessible after “I, Aris...”, Volume 2, Chapter 1, Episode 5. That creates an early branch; it does not remove Volume 2, Chapter 2 from Volume F’s requirements.

Volumes 3–4: The Eden Treaty and RABBIT Squad

Volume 3: Eden Treaty

Trinity and Gehenna are preparing a treaty despite their longstanding hostility. The Make-Up Work Club and Arius Squad sit at the center of an arc where school politics and individual loyalties become inseparable.

Read its four chapters in sequence:

1. Make-up Work Club, Here We Go!
2. Paradise Paradox
3. Our Stories
4. Kyrie of the Forgotten Gods

Complete the fourth chapter’s “Epilogue” before Volume F. This also satisfies the stated entry requirement for Volume 6, which returns to Arius.

Volume 4: Rabbit of Caerbannog

After SRT Special Academy is disbanded, its former students face life without their school. RABBIT Squad and FOX Squad bring questions of duty, institutional authority, and belonging into focus.

1. Finish “Eden Treaty Signing Ceremony Part 1”, Volume 3, Chapter 3, Episode 5, to unlock Volume 4.
2. Read Chapter 1: RABBIT Squad, Begin Operation! through “Fox in the Hole.”
3. Return for Chapter 2: We Were RABBITs! after Volume F.

Volume 4’s second chapter requires “Afterword 2” from Volume F. Finish the opening RABBIT chapter before the crossover, then save its continuation.

Volume F: Where All Miracles Begin

Volume F brings students from across Kivotos together against a destructive threat. The earlier school arcs establish the relationships that give this larger conflict its weight.

Before opening it, complete all four requirements:

Earlier arc	Required completion
Foreclosure Task Force	Volume 1, Chapter 2, Episode 20: “Epilogue”
Clockwork Flower Pavane	Volume 2, Chapter 2, Episode 25: “Millennium Science School”
Eden Treaty	Volume 3, Chapter 4, Episode 27: “Epilogue”
Rabbit of Caerbannog	Volume 4, Chapter 1, Episode 20: “Fox in the Hole”

Then follow Volume F’s chapter sequence:

1. Operation Recapture Schale
2. Operational Plan: Nisir's Summit
3. The Ark of Atrahasis Conquest
4. Phrenapates Showdown

Continue through Chapter 4, Episode 12: “Afterword 2.” Several later chapters use that specific episode as their prerequisite, including the Abydos continuation, RABBIT Squad’s second chapter, and Volume 5’s opening.

After Volume F: Return to Abydos, RABBIT, and Hyakkaryouran

The story branches again after the crossover. Track chapter requirements individually rather than treating the volume numbers as a single timeline.

1. Return to Volume 1, Chapter 3: Traces of a Dream. Its opening becomes available after Volume F’s “Afterword 2.”
2. Continue Volume 4 with Chapter 2: We Were RABBITs! Its opening, “The Fox’s Dream,” has the same Volume F requirement.
3. Begin Volume 5: Hyakkaryouran. Its first chapter also requires “Afterword 2.”
4. Finish the Abydos continuation before Volume 5, Chapter 2. That chapter additionally requires “Epilogue 2,” Volume 1, Chapter 3, Episode 43.

Volume 5 centers on the Hyakkaryouran Resolution Council, a group struggling with its lack of purpose. Its chapter titles reflect that focus: Like the Flower That Wishes to Bloom and To You, Who's Trying to Bloom Alone.

The dependency to remember is Abydos Chapter 3 before Hyakkaryouran Chapter 2. Completing Volume F alone satisfies the opening requirement for Volume 5, but not the requirement for its continuation.

Volume 6 and Volume EX: Arius and Decagrammaton

These arcs follow different threads, so their entry requirements deserve separate attention.

Volume 6: Oratorio of Days Gone By

Volume 6 brings Sensei, Saori, and the rest of Arius Squad back toward their former school and the students still living there in isolation.

Its opening requires Volume 3, Chapter 4, Episode 27: “Epilogue.” Read the chapters in this order:

1. Sights Beyond the Boundary
2. Saying Goodbye to Yesterday
3. Ecclesia for the Future Left Behind

Finish Eden Treaty before starting this arc so that the squad’s history and relationships carry their intended context.

Volume EX: Decagrammaton

Decagrammaton follows Sensei and the Super Phenomenon Task Force as they investigate an unusual presence across Kivotos. It began outside the main-story structure before becoming Volume EX.

Its chapters are:

1. Snake of Wisdom
2. Flaming Sword
3. The Sky of Unity

The opening episode of Chapter 2, “Glacial Sea, Again,” requires completing Volume F’s “Afterword 2.” Plan around that gate when fitting this investigation between the school-focused arcs.

Act 2: General Student Council, Lore Pursuit, and Gehenna

Act 2 introduces a new prologue and restarts volume numbering. Its Volume 1: Fire and Shadow is a separate arc from Act 1’s Volume 1: Foreclosure Task Force.

Follow the opening requirements this way:

1. Read the Act 2 Prologue through Episode 4.
2. Begin Volume 0: General Student Council.
3. Finish Volume 0 through Chapter 1, Episode 10 before starting Fire and Shadow.
4. Read Volume 0 through that same point before Lore Pursuit to follow its opening warning.

Volume 0 focuses on Rin, her workload, and the strain left by the General Student Council President’s absence. Lore Pursuit follows FOX Squad as unexplained abnormalities called Lore appear around Kivotos and students disappear.

Japanese and Global chapter releases follow different schedules:

Act 2 installment	Japanese release	Global release
