Kurohyō 1: how to unlock all 20 fighting styles
The style tree is worth keeping beside you while you play. Several styles need other styles at specific levels, and three of the basic styles come from side quests. If you skip those quests, you also cut off the advanced styles that depend on them.
These are fighting-style levels, not Tatsuya's character level or the stats you buy at Tsukahara's dojo. Leveling Tatsuya to 30 won't automatically satisfy a requirement for level 3 Boxing.
English names vary between guides and patches. I've included the Japanese names for the Extreme styles so you can match them without guessing.
THE SIX BASIC STYLES
1. Street Fighting/Brawling: available from the start.
2. Boxing: learned through the Chapter 2 story.
3. Ancient/Traditional Martial Arts: in Chapter 4, respond to Yuki's message by meeting him near Mach Bowl, behind Theater Square. Accept his training and win the rematch.
4. Karate: in Chapter 5, walk through Theater Square to receive Fujimoto's message. Visit West Park and defeat the five karate club students.
5. Pro Wrestling: in Chapter 7, enter Le Marche on Showa Street East. Speak to Hyuga, accept his rematch and win. This also awards the Wind secret tome.
6. Jujutsu/Jiu-Jitsu: learned through the Chapter 8 story.
THE SEVEN COMBINATION STYLES
7. Muay Thai: Street Fighting 3 + Boxing 3.
8. Lucha: Street Fighting 3 + Pro Wrestling 3.
9. Fighting Kenpo: Boxing 3 + Karate 3.
10. Mixed Martial Arts/MMA: Jujutsu 3 + Street Fighting 3.
11. Bajiquan: Jujutsu 3 + Ancient Martial Arts 3.
12. Weapon Mania: Pro Wrestling 3 + Street Fighting 3.
13. Chinese Kenpo/Kung Fu: Ancient Martial Arts 3 + Karate 3.
Yes, Lucha and Weapon Mania share the same prerequisite combination. You haven't read that wrong.
THE SIX EXTREME STYLES
14. Extreme Hard Arm (剛腕の極み): Boxing 5 + Muay Thai 3 + Fighting Kenpo 3.
15. Extreme God Leg (神脚の極み): Karate 5 + Chinese Kenpo 3 + Fighting Kenpo 3.
16. Extreme Softness/Soft and Hard (柔剛の極み): Jujutsu 5 + Bajiquan 3 + MMA 3.
17. Extreme Awakening (覚醒の極み): Street Fighting 5 + MMA 3 + Weapon Mania 3.
18. Extreme Fortitude (不屈の極み): Pro Wrestling 5 + Weapon Mania 3 + Lucha 3.
19. Extreme Wild Dance (乱舞の極み): Ancient Martial Arts 5 + Bajiquan 3 + Chinese Kenpo 3.
THE FINAL STYLE
20. Extreme Man/Extreme Being (極めし者): raise all six Extreme styles to level 2.
That's the final step. Unlocking each Extreme style isn't enough; you need to finish leveling them as well.
HOW TO WORK THROUGH IT
Start by getting Street Fighting and Boxing to 3. That opens Muay Thai early. As the story continues, pick up Ancient Martial Arts, Karate and Pro Wrestling from their substories instead of leaving all three until the end.
When a style reaches the level you need, decide whether you're working toward its Extreme branch or opening another combination. For example, staying with Boxing until 5 helps the Hard Arm route, while switching to Karate lets you start opening Fighting Kenpo and Chinese Kenpo once their other requirements are met.
If your goal is every style, work through the full tree. If you're trying to get past one difficult fight, check what you can unlock now and use something that suits that fight. You don't need the final style just to make progress through the story.
