@Autistickouji, Continuing our convo from Comment section.
Do not start from y1v1. Are the students reacting from their entrance or y1v3 or y1v11.5? There should be a reason behind character growth. There are a lot year 1 reactions. So you should include a lot of y2.
For Kushida: Start by telling them about a traitor. Leave them guessing. React to y1v5. All the scenes relevant to the traitor. About AK thinking about the traitor in Zodiac exam. AK talk with Kei. Lunch Break. Final Ryueen and Suzune talk. React to y1v6. About the bet. End result. Ryueen and Kushida talk. By then the class should know the traitor is academically capable. React to y2v5. React to the exam. Don't reveal Kushida name until thins. Let it be revealed here. Then start revealing why AK was wary of Kushida. Kushida rant scene from y1v1. Kushida talking about her past in y1v6. Hoow AK planed to expel Kushida in y1v6. Horikita wants to make an ally of her. AK and Kushida talk in y1v9. Horikita and AK talk about Kushida in y1v11.5. Yagami, Kushida and AK talk in y2v2. Reveal of 20 mil bounty. Can be used for next arc. Ichika and Kushida scene in y2v3. You can take her development from there.
For Nagumo, you can start with his monologue. Manabu and AK talk in y1v4.5. Ryueen, AK and Manabu talk in y1v7.5. AK asking Suzune to join the Student council. All relevant scenes in y1v8. Sakayanagi and Nagumo talk in y1v9. Manabu and AK talk about Nagumo in y1v11.5. AK and Suzune bet. Results of that bet. Nagumo and Fuka talk in y2v2. All relevant scenes from y2v3 and y2v4. Nagumo surveilance of AK in y2v4.5. AK and Fuka talk. AK and Nagumo bet about Student Council elections. You can take it from there.
Build suspense. Keep students guessing. Plan their growth. Have students react to how resourceful AK is. Don't reveal Kei as AK's partner until it's her arc.
