Sushi

Source: npc/quests/quests_amatsu.txt

1. In Amatsu, follow the Sushi Quest branch with the local cook NPC.
2. Confirm dialogue options to help with fish preparation/delivery.
3. Script grants Sushi at several points: getitem 551,10, getitem 551,1, and getitem 551,20 in the later stage.
4. If inventory space is insufficient or prior steps are incomplete, the next reward is blocked.
5. Keep extra Sushi, since it is reused as a consumable in related quests.
