Aniimo First Companion achievement: pick a starter

Aniimo First Companion achievement: choose Helion or Lunara in the opening starter sequence and continue until that companion joins you. The requirement accepts either choice; it does not ask you to collect both.

Single source method draft

1. Continue the opening sequence to the starter cavern.
2. Choose the companion you prefer. Aniimo best starter: Lunara or Helion? compares their play styles.
3. Finish the joining dialogue or sequence, then check your platform's achievement record.

Do not restart just because another guide recommends the opposite starter. The official requirement explicitly names both as alternatives. A current route to the unchosen starter remains a separate question, not a prerequisite for this award.

Evidence and gaps

Single source: the authored roadmap supplies the cavern and joining trigger. Steam supplies the requirement. Their roles are different, so this does not qualify as two independent methods. October 30 notes do not name an unlock fix for it.

Missable status, a failed-unlock recovery route, cross-platform synchronization and exact timing remain UNSURE. No numerical difficulty or time estimate is invented. The documented story action uses one player, without establishing offline play. No Hizzle in-game testing.
