Heroic OSF Achievement
Completed 30 quests.There will be a total of 68 side-quests available in the game (34 with each character), so you can skip quite a few and still get this achievement. None of them are missable either, so you can wait until you complete your second playthrough and just do the easiest ones for each character if you'd like. You'll obtain side-quests from characters in the four safe zones in the game (Suoh City Ryujin Ward, Seiran City, Musubi’s, OSF Hospital), marked by a white diamond on the map. Quests are mostly just kill or fetch requests, though some will have specific methods of killing the enemy you need to follow, so pay attention to that. You can check the Library in the menu to find where enemies will spawn.
