35 substories are part of the main narrative threads (marked with a gold exclamation mark)
17 are purely optional, but 4 of those are **missable**—they vanish after you start Chapter 10
**The 4 Missable Substories** (complete before Chapter 10):
"The Lost Cat of Kamurocho" – starts at the park bench near Theater Square
"A Drunkard's Confession" – bar in Champion District, only available at night
"Ramen Rivalry" – Ijincho ramen shop, requires you to have eaten 5 bowls from different stalls first
"Ghost of the Pier" – Seaside pier, triggered after finishing substory #18
**Substory Rewards**
Each substory gives 3,000–15,000 XP, ¥10,000–¥500,000, and often unique gear. The best reward comes from the final substory chain ("The Dragon's Legacy"): a permanent 10% damage boost to all attacks.
Pro tip: Use the in-game smartphone app "Substory Tracker" (unlocked in Chapter 2) to see completion percentages per district. No more running around blind.

**Best gift for early game**: Silver necklace (¥15,000) – raises Charm by 1.5 bars
**Fastest money**: Run the club on Friday nights (peak customer traffic, +40% revenue)
### Dragon Kart
12 tracks, 4 vehicle classes (Speed, Balance, Armor, Drift). For the story mission, pick the Balance class—it's forgiving on turns. The hardest track is "Seaside Loop" with 15 sharp corners; use Drift class here with maxed handling upgrades.
### Arcade & Classic Games
**Virtua Fighter 5 R**: Beat Dural with Akira (spam the "palm strike" combo: forward + punch, then kick)
**Sega Bass Fishing**: Use the red lure for all lakes; cast at 75% power for max distance
**New: "Dragon Hunter"** (light gun shooter): 10 stages, boss at stage 7. Focus on headshots for bonus time

Business Management: From ¥100K to ¥50M/Week
The Business Management minigame is back, now with 15 rival CEOs and a new **stock market mechanic**. Here's how to dominate.
### Phase 1: The Grind (Chapters 4–7)
Start with ¥100,000 loaned from the bank. Buy the "Sushi Shop" first (cost: ¥80,000, profit/day: ¥12,000). Reinvest everything into upgrades until you hit ¥500,000/week.
### Phase 2: The Expansion (Chapters 8–12)
At ¥500K/week, buy the "Electronics Store" (¥450,000, profit/day: ¥35,000). Then acquire the "Restaurant Chain" (¥1.2M, profit/day: ¥90,000). This triggers the stock market subgame.
### Phase 3: Stock Market (Chapter 13+)
Here's where the real money flows. Your company goes public at ¥100/share. Buy when the price drops below ¥70 (happens randomly after news events). Sell when it hits ¥150+. Use the "Media Manipulation" investment (costs ¥2M) to cause a temporary price spike.
**Comparison Table: Best Businesses by ROI**
| Business | Cost | Daily Profit | ROI (days to recoup) |
|----------|------|--------------|----------------------|
| Sushi Shop | ¥80,000 | ¥12,000 | 6.7 |
| Electronics Store | ¥450,000 | ¥35,000 | 12.9 |
| Restaurant Chain | ¥1,200,000 | ¥90,000 | 13.3 |
| Hotel | ¥5,000,000 | ¥300,000 | 16.7 |
| Casino | ¥15,000,000 | ¥800,000 | 18.8 |
The Casino has the worst ROI but is required for the "King of Yokohama" achievement. Buy it last.
**Profit cap**: ¥50 million per week. After that, the game forces you into a final boss fight against the "Mystery Investor" (actually the secret final substory).

Use the practice mode (unlocked after first play) to learn note patterns
For "Dragon's Roar": memorize the rapid section at 1:45—it's 32 notes in 4 seconds
Best song to earn money: "Corporate Climber" (¥50,000 per perfect play)
Worst: "Heart of a Hero" (only ¥15,000, takes 4 minutes)
