Team Effort

All 6 of these must be met. Each one counts once it is met and your save keeps it, so the order does not matter:

• Extract from a run as Milk after defeating at least 1 boss in it.
• Extract from a run as Matcha after defeating at least 1 boss in it.
• Extract from a run as Coffee after defeating at least 1 boss in it.
• Extract from a run as Rum after defeating at least 1 boss in it.
• Extract from a run as Chicha after defeating at least 1 boss in it.
• Extract from a run as Anchan after defeating at least 1 boss in it.

The game re-checks it every time you extract from a run.

You read your achievements at the board in the hub.

It shows on that board only after Anchan joins you as a playable character.

• Gambling Chip: you can keep 1 more wager active at once. The reward shows 2, but claiming it raises the limit by 1 only.

You claim it from the achievement list at the board once the achievement is unlocked.
