I would first pause time momentarily to assess the situation and locate my friends within the burning building. By slowing down the progression of the fire, I give myself the opportunity to devise a safe rescue plan. Then, I would carefully navigate through the building, avoiding any collapsing structures or dangerous areas heightened by the fire's intensity. As I reach each friend, I would temporarily speed up time, just enough for them to safely exit the building. Once they are secure, I would revert to my normal time manipulation to strategically save the others. Lastly, when all my friends are safe, I would use my time-warping abilities to alert the emergency services earlier than their actual arrival, ultimately preventing the fire from causing even more damage.
Your friends are trapped in a burning building, and the fire is spreading rapidly.
Imagine you are an anime character who has gained the ability to manipulate time. Explain how you would use your power to save your friends in a challenging situation.
