Diamond is Unbreakable - Chapter 72 
Shigechi's Harvest, Part 3 (｢重ちー｣の
After that Josuke, Okuyasu, and Shigechi collected store coupons in order to get prizes, Okuyasu, and Shigechi wait nervously outside of the Kameyu department store, wondering if their plan is working. Josuke comes back with 65,000 yen in his hands, which greatly exceeded everyone's expectation, and the trio is overjoyed to have succeeded. However, Shigechi is getting too attached to the 65,000 yen and only gives them 10,000 yen whereas he agreed to give them half of the money. Shigechi gives himself excuses, explaining that Harvest did all the work and that he's entitled to a greater share, underestimating Josuke's involvement in the plan.
His hypocrisy infuriates Okuyasu, who begins to antagonize him, but Josuke stops him from going too far, reasoning that they should act mature and leave it at that. Okuyasu accepts but a wedge definitely appeared in their friendship. Josuke proceeds to throw out the seemingly useless tickets Harvest collected, but Okuyasu hopes that a stray winning lottery ticket might be among these. After agreeing with Shigechi to take half of what he will collect, Okuyasu luckily finds a winning national lottery ticket worth 5,000,000 yen. While Okuyasu and Josuke are overjoyed by this finding and are already celebrating, Shigechi's greed is getting at him.
