The newly appointed teacher, 'Nishida,' arrived at a school in a sparsely populated district that had only one class. The school also had a principal who schemed to send students to university through backdoor admissions. Nishida, with an unusually strong sense of justice, decided to show the principal that he could help students advance on their own merits, leading to a conflict between them. First, Nishida aimed to teach his students the importance of learning by using his own anus as the subject of his lessons. He carefully explained the mechanics of the anus and rewarded those whose grades improved. After reconciling with the principal and successfully expanding his anus, he conveyed his message of never giving up through public 2-hole sex at the highest difficulty level.
