Big Hitter

Clear 10+ baseball-cage sub-missions during Shinada's part — several are one-shot with no retry, so take every offered mission immediately.

1. 1

   1) Open Shinada's part by stopping at the Nagasugai batting center — once the Oniaeda coach line activates, side missions begin spawning.

2. 2

   2) Talk to the rotating NPC at the cage entrance (not a board) to accept jobs — some expire after one in-game day, so run them right away.

3. 3

   3) Apart from straight batting drills, the rival-team recruitment line counts too — pick up both kinds.

4. 4

   4) Ten cleared missions fires the trophy. Shinada's part is short — prioritize side missions over unrelated minigames.
