The verified update
Yes. Natsume says helping villagers and contributing to Teradea’s development earns Happilia.
This briefing isolates one part of the public record so that a player can act on the confirmed detail without mistaking a broad trailer, preorder listing, or product page for a complete specification.
What the source establishes
- Happilia is gained through helping villagers.
- Development of Teradea is part of the same system.
- No exchange rate, level table, or complete reward list is published.
Why it matters now
Feature guides should describe Happilia as a development-linked resource without inventing an economy.
For editorial tracking, this topic should be reviewed again when Natsume publishes another game-specific release, when a verified platform store exposes new metadata, or when launch-day testing can answer the remaining operational question.
What this update does not establish
The progression connection is factual, while exact thresholds and unlocks remain launch-day data.
No unannounced feature, value, route, schedule, performance target, item table, or story outcome has been inferred. The distinction is important because the game is still unreleased.
