What to do next
SourceStockpile ¥9,999,999 in Kiryu's wallet at once. The fastest route uses the one-time "Zero Jewel" cheat item from Chapter 6's Rikiya line — feed it into roulette/casino for explosive growth. The trophy checks current balance, so verify before any big purchase.
1) During Chapter 6 with Rikiya in tow, complete his Kamurocho line to receive the one-shot Zero Jewel. Keep it separate so it doesn't get sold by mistake.
2) At the Kamurocho casino, start a roulette session — using the Zero Jewel rigs the next spin to land on 0 (green). Max-bet every chip on 0 in that single spin.
3) Hitting 0 pays out 35× — convert the chip pile into high-value prizes like Platinum Plates (¥500,000 each) at the prize counter, then cash them at the pawn shop.
4) If still short, top up with minigames (massage, golf, fishing) and cabaret jobs. The trophy pops the instant your balance ticks ¥9,999,999.
Watch for
- The Zero Jewel is a one-shot Chapter 6 item and consumes on use — only roulette accepts it, so don't waste it elsewhere.
- The trophy reads current balance — buying gear or investing in property drops it instantly. Knock out other money-dependent trophies at the same balance peak.
