The short answer

Steam advertises island exploration, joining a band, fishing, seashell diving and Green Sprites forest expeditions outside class. Release coverage also names Forests and Fairies. Exact unlocks, schedules, collectible lists and rewards are not yet verified here.

Activities are invitations, not a completion checklist

The official overview gives a sense of how life can extend beyond lectures and the university garden. It does not establish that all activities are available in the opening demo or that they share the same unlock path.

If an activity appears in a trailer but is not yet available in your session, that alone does not mean the game has failed to trigger it. Check the story and prompts in your own build before applying a guessed prerequisite.

Fishing and seashells need real collection data

Fishing and diving for seashells are explicitly named. That confirms two activities, but not a list of species, rarity tiers, weather rules or sale prices. We do not borrow collectible names or mechanics from another life simulation to fill an empty table.

A future collection tracker will need a verified set of entries before its percentage can mean full completion. At present, a personal note about what you found is useful, while a global “missing items” list would imply information the wiki does not have.

Keep names and evidence levels visible

Green Sprites is a name in the official Steam description. Forests and Fairies appears in Gematsu’s release coverage as part of the developer-supplied overview. The different provenance remains visible rather than being flattened into a final rules database.

For your own plan, enter the activity or meeting your game actually offers. The day planner can keep the reminder, but it cannot know a final club schedule. Joining conditions, event conflicts and rewards will need their own build-specific observations before they become guide steps.
