1. Leading the top class

   Strong evidence

   Season 2 onward

   Sakayanagi holds her class together and keeps it in first place by managing rivals and allies. Leadership of a large group in a competitive environment takes organisation and judgement. The show demonstrates her influence by how others react to her, so we count it as strong evidence for strategy. The class follows her willingly, which is itself evidence of the respect her judgement commands.

2. Chess-like planning

   Strong evidence

   Season 2 onward

   She likes to think of the school contest as a game of chess and sets up positions in advance. The metaphor is often stated, and the plans fit it. It shows a systematic and long-range approach, but it also shows how much she depends on a model that a clever opponent can exploit. She sets traps several moves deep, and she often accepts a short-term loss for a long-term gain, which is a sign of genuine strategic thinking and not mere cleverness.

3. Studying her rivals

   Moderate evidence

   Season 2 onward

   Sakayanagi collects information about opponents, and uses it to predict their moves. This is a key part of strategy and shows patience. The extent of her research is told as much as shown. She profiles weaker and stronger students alike, noting habits and pressure points, and she uses what she learns at the moment it counts. The method is patient and consistent, and it fits a mind that prefers preparation to improvisation.

4. Knowing Ayanokoji's past

   Moderate evidence

   Season 2 onward

   She recognises that Ayanokoji is not an ordinary student and tests him. Seeing through his disguise is a sign of perceptiveness. It also drives her main weakness, since she becomes obsessed with him. She sees through his act when almost everyone else is fooled, and she tests it with a challenge. That insight is genuine, although it sets up the obsession that later limits her.

5. Playing despite physical limits

   Minor evidence

   Series-wide

   Her health prevents her from taking part in many activities, so she leans on planning and delegation. Adapting to those limits shows resourcefulness. It is a small point in the overall picture. Her cane and her health problems mean that she cannot rely on action, so she uses influence and information, and she makes a virtue of it. The adaptation is credible and consistent across the story.

1. Fixation on one opponent

   Season 2 onward

   Her single-minded focus on Ayanokoji skews her decisions, and a more flexible strategist would give the rest of the school more attention. Her desire to beat one person overrides a wider view of the contest, and the school's other threats receive less attention than they should.

2. Dependence on others for action

   Series-wide

   Because of her health, she needs people to carry out her plans. When they fail, the plans collapse, which is a structural weakness. Her plans need loyal helpers, and when one wavers or is outplayed, the design can fail without her being able to step in herself.

3. Limited novel invention

   Series-wide

   Her successes come from careful application of known ideas. We see fewer signs of the kind of original thinking that would justify a higher number. She sticks to proven forms of pressure, such as information, positioning and psychology, and rarely produces a surprising new method.
