What to do next
SourceWin every underground Coliseum tournament (standard + S-rank). Unlocks past Ch.6; later cups impose weapon bans or bare-fist rules — max styles + healing required.
1) After Ch.6, enter the underground Coliseum and start the first tier.
2) Check each tier's rules (no weapons, bare-fist, etc.) and stock healing. Tiers run Standard → Warrior → Champion → God.
3) Winning the God-tier final fires the trophy and unlocks Komaki training nodes.
Watch for
- Chasing it alongside the other Coliseum achievements is efficient.
