Obtained: Chapter 4 – Approach the empty park in the Bar District (day)
After the brief cutscene, wait a little while until the objective appears again on the map then return to the park and speak with the Tired Man. You’ll agree to check in on the persimmon so wait awhile again then return when the objective appears. Defeat the Sumo Wrestler. Afterwards, you’ll need to wait yet again for the objective to reappear. When it does, return to the tree to find a sniper shooting at the fruit. To stop him, you’ll engage in combat. Defeat him then wait again for the objective to appear. This time when you return to the tree, you’ll find a guy hammering a straw doll to it. Defeat Kugitani in battle then wait one last time for the objective to appear. When it does, approach the tree for the last cutscene.
