Story related. Unmissable. Mamiya’s Legend Mode is unlocked by completing Chapter 2 or 3 of Kenshiro’s story. There are 5 chapters in her story. She is a crossbow user and her charge attack will instant kill most enemies. Against big-sized enemies and bosses, charge and shoot, run away to a safe distance when they approach you and repeat. The fight with Raoh though, is more difficult than the rest. This trophy unlocks after the (skip-able) credits.

Be sure to enter the fight with full spirit bars (I had 2 bars). For the 1st phase shoot your crossbow with (non-charged) at him all the time. You’ll take some damage for sure but there’s a health item at the back. Do this until you enter the second phase. When he’s done raging, get close and activate Spirit Aura, melee him like crazy and use your Hyper Signature Move just before the Aura ends. Grab the full spirit refill item in the crate near the entrance and repeat this again so he goes down.

This trophy should come with time along with the other kill trophies below.  You may try the grinding method suggested below provided by TheProphetUK:

Another quick way to farm kills is on Shin's Deam mode, 2nd level. You need to kill 2 bosses to finish the level - Zeed and some other guy. The first is in the bottom left of the screen. Once he's dead the gate in the bottom right opens. Make your way there but once the gate is in sight STOP and let the hordes of enemies attack you. Remain here killing everyone and they will constantly respawn and run out and attack you. The enemies are weak and are mostly one hit kills. Using your spirit gauge with L2 and spamming it also works. I was racking up 100 kills every 1-2 minutes

Kenshiro and Raoh are the main users of the Hokuto Shinken fighting style, though any other character can use it once they've learnt the Extrinsic Skill "Hokuto Shinken Wisdom" and equipped it. Normally, as any of the 2 characters mentioned above, for a kill to count, you must kill an enemy with a combo that ends with . The enemy will deform and/or explode if done right.

Despite Kenshiro and Raoh being the main practitioners, the easiest way to farm this is to actually use Jagi's charge attack which inflicts Hokuto Shinken status. Playing Chapter 1 of his Dream mode over and over will net you the kills very easily.

For any character (including Kenshiro & Raoh) that equips the Hokuto Shinken Wisdom skill, any attack they use to defeat an enemy will count towards this trophy, including regular attacks. For now, Dream Modes are the best place to farm this.

Rei, Shin, and Thouzer are the main users of the Nanto Seiken fighting style, though any other character can use it once they've learnt the Extrinsic Skill "Nanto Seiken Wisdom" and equipped it. Normally, as any of the 3 characters mentioned above, for a kill to count, you must kill an enemy with a combo that ends with . The enemy will die with a slashing effect if done right.

Using Rei, the best way is to spam after a successful Timely Strike. GenocideHeart adds that Thouzer is also a good character to use for this. For any character (including the 3) that equips the Nanto Seiken Wisdom skill, any attack they use to defeat an enemy will count towards this trophy, including regular attacks. For now, Dream Modes are the best place to farm this.

Toki is the main user of the Hokuto Ujoken fighting style, though any character can use it once they've learnt the Extrinsic Skill "Hokuto Ujoken Wisdom" and equipped it. For a kill to count, you must kill an enemy with a combo that ends with . The enemy will glow and/or float, then explode if done right.

Using Toki, the best way is to spam () and press when the animation is about the end to cancel the move and skip the part where he coughs, so you can repeat the attack again. Another good combo to use when you're surrounded by a huge crowd is (). Good places to farm this are in Chapters 2 and 3 of Toki's Dream Mode, where he is "cured" and no longer coughs. Completing his Dream mode also unlocks his "cured" version for all other missions.

For any character that equips the Hokuto Ujoken Wisdom skill, any attack they use to defeat an enemy will count towards this trophy, including regular attacks. For now, Dream Modes are the best place to farm this.

As explained in the Game Basics section (see Roadmap), SMs are activated by pressing when you have at least one Spirit Reserve bar available. The best SM by far is Jagi's Iron Blast that has a 2/4 damage rating, has a 180 degree range and costs 1 Spirit Reserve.

An alternative is Kenshiro's Heavenly Destruction, 3/4 damage rating with 360 degree range but costs a whopping 3 Spirit Reserves. In Dream Modes you can run up to enemy bases, get in the midst of the group of enemies that spawn then unleash your fury on them.

His lifebar starts with 3 segments. The first segment can be depleted by normal attacks. Thereafter, he starts will power up and charge at you. When you see him preparing to charge, run behind a pillar so that he will get stuck in the pillar instead, and there’s your opportunity to counterattack. For the last segment you will have to activate your Spirit Aura () in order to counter his Spirit Aura or you won’t be able to damage him. Proceed to pound on him with normal attacks until he kneels down, then finish him off with a finisher.

Like most big-sized opponents, the armor icon displayed when you attack Fang indicates that they are resistant to single attacks. You will need to break their armor gauge by consistently attacking him with alot of hits. When his armor breaks he will be in a Meridian Shock stage, so use your signature moves on him. Halfway he will summon his goons which are just fodder for you to refill your spirit gauge and get more Sig.moves stocked up. When he appears just repeat more of the same and he’ll go down.

Like Shin, the fight with Jagi has 3 parts. The first part can be easily done with normal attacks. The second part gets annoying as he first destroy some oil tanks and flood the middle part of the arena with oil. He will jump out of reach, summon cages to trap you, and throw explosives that travel some distance. You can destroy the cages, and the fire won’t do much harm. When he reappears in the middle of the arena, I suggest quickly to break his defense and quickly followed up by a Signature Move. In the third phase, he will start to use Spirit Aura, and you need to counter it with your own to damage him. Pummel away and use the finisher when he drops.

This guy is moves fast but is pretty easy. He counters your attacks once in awhile but he doesn’t hit hard at all. If he locks onto you with a combo just use your Signature Move to counter it. Just keep at it with normal combos. He uses Spirit Aura in the third phase so remember to use yours.

By now you should know how to deal with big sized enemies. Uighur is slow and none of his attacks are any different from previous enemies of the same type. Pound away until the his health drops to 50%, where he will summon some goons. Despatch them and continue with more combos and he’ll go down easily.

This is your first real test. This guy is annoying, hits hard and is tough like an elephant. The fight start with him atop his horse and he will attempt to run you down. I’m not sure if this is a time limited fight and you just need to run down the clock, but what I do is roll out of the way and use to do some damage.

After a cutscene he’s now on the ground and he’s seriously gay. The best way to fight him is to use the jump kick + which will knock him back. Use it a couple of times and his defense will break as well and the good thing about this attack is you’ll probably land behind him, which allows you to put in a good x3 combo. Keep repeating this and use the Seven Stars of Death signature move when you have the opportunity.

This guys has some killer moves, but rarely uses it. I was able to keep him in a semi-permanent juggle by using and and defeat him easily.

Story related. Unmissable. Not particularly difficult at this point if you have decent upgrades, he’s just more of the same.

Story related. Unmissable.

He’s slightly tougher than previous bosses but still fights the same. If you use the signature move “Awakening of the Senses” you can inflict Meridian/Spirit Shock which makes him take more damage.

By now you really should be familiar with all the boss fights and what to do because it’s the almost the same with each one of them. The arena is small so take advantage of this with moves that send him flying into the wall. In the 2nd phase he summons 3 weak clones of himself which you need to defeat and in the 3rd phase he uses Spirit Aura which you need counter with your own.

Story related. Unmissable.

The first phase is more of the usual hit-him-till-he-gets-mad routine. The second phase is extremely annoying. The white panels on the floor are pressure traps that shoot spikes if you’re standing on them. Ryuga will also summon a bunch of minions for you to deal and once you’ve dealt with them he reappears with his Spirit Aura thing. Do as you must.

This is an insanely easy fight if all you do is spam in all three phases. In the last phase activate Spirit Aura and use your Hyper Signature Move to quickly end this easy fight.

Story related. Unmissable.

Like the last fight, all you have to do is spam . If you find yourself too far from him, use + to jump kick and quickly close the distance.

Despite Toki’s constant coughing interrupting the flow of the battle, this fight isn’t hard at all. I personally use all the time and in the 2nd phase I activate Spirit Aura to damage him and pull off a Hyper Signature Move that actually does some real damage compared to the normal one.

Story related. Unmissable. This is in the 3rd and final chapter.

This time Raoh is stronger in every aspect. I stuck with the same combo strategy as before and making full use of my Spirit Aura and Meridian Shock effect from Toki’s Hyper Signature Move.

Story related. Unmissable. Rei is an incredibly easy and overpowered character to use. He’s quick and his Nanten Seiken fighting style will prompt you to use Timely Strikes by pressing in the middle of your combos or when an enemy is about to attack you . If the Timely Strike successfully lands on an enemy, Rei enters a powered up state (and counterattacks if prompted before an enemy attack) where he literally slashes everything into pieces, and can even counter bosses with Spirit Aura, tearing all of them apart with ease.

Story related. It’s a very short chapter and Juda is a pushover as usual. I used Spirit Aura to end the fight faster.
