Uchiha Sora guessed that once he fulfilled his agreement with Uzumaki Chiho, he might gain the largest amount of credibility points he had ever received.
Two key factors affected the acquisition of credibility points: one was the lender's strength, and the other was the difficulty of fulfilling the agreement.
