At any point during this fight, Yujiro's AP, durability, and speed can hop up to 4x higher because of DB, Roll Kick allows Yujiro to dodge an attack and counter at the same time, Udonde stance is literally made to defend from attacks in all directions without even facing a different direction, Yujiro could literally Bite through Wolf's limbs if he tries to grapple, Aiki also hard counters that Class G flex, Benda negs durability GG, 0.5 Seconds Unconciousness lets Yujiro skip his reactionary phase and attack Wolf while he can't do anything to defend, Defensive Xiao-Lee negates all forms of physical damage that Wolf can do and Offensive Xiao-Lee dishes them right back, Yujiro can inflict Madness with his aura and it also applies a constant physical damage, his analysis allows him to see Wolf's weakness at a cellular level and it's just his passive eyesight, Yujiro can literally analyze his entire physical moveset, with Apnea Rush he can throw 100 punches in under 5 seconds for 5 minutes, leaving 0 room to counter, or use Vacuum Palm and instantly knock Wolf out by forcing him to breath 6% oxygen, he can use Adrenaline to amp his energy, he can use the Axe Kick to smash Wolf to pieces, he can use Ball to negate physical damage as well, he can use the Bodhisattva Fist to blow a hole in Wolf, he can use Bukkotsu to destroy Wolf's pharynx, he can use Chokuzuki and kill him in one hit, he can use Chop-Blow and knock Wolf's head off, he can use Cord Cut to rip out the nerves in Wolf's eyes to blind him and his arms and legs to incap Wolf, he can knock out Wolf or kill him with a Crotch Kick, he can use Crushing Fist to use Wolf's speed against him, he can use Dashin to paralyze Wolf, Destructive Force to gore Wolf, Dropkick Wolf and subtract his torso from him, use Endorphins to negate any pain, Enzuigiri to incap Wolf's medulla, he could use Eyeground Crush to blind and kill Wolf back to back, he could use a simple Feint and catch him post teleport, he could use the Five Vital Points Consecutive Attack to incap Wolf's entire body, the Flying Swallow Barrage to blitz Wolf with a combo, the Forehead Blow to kill him while Wolf attempts a grapple, he could go with the Four-Stage Kick and take him apart piece by piece, he might use the Fumasatsu to slip one of Wolf's strikes and dislocate his jaw, following up with a Goutaijutsu to gore him, or Hand Pocket to blitz him, or Headbutt in case of grappling, or maybe the Hitless Blow, a High Hypersonic+ punch that blows Wolf to chunks, or use Invisible Squash to blind Wolf and use Ippon Ken knock him out with pressure points, or use the Jab to blitz, or Knee Drop Wolf's head off, or use Knuckle Arrow to hold Wolf in place by the top of the head and knock it off with a punch, or use Kokoken to stop Wolf from being able to think or react and blast through him with a Forward Leaning Stance dash, or use the Mach Punch, a less effective Hitless Blow, to achieve similar effects, or the Maeba Stance to counter Wolf right before he attempts to hit Yujiro, or get close enough that Wolf can't swing his blade and use Musunkei, which can be used at full force from 0mm, or Myoukou to pressure point knock him out, or use the No-Motion Jump to attack Wolf without Wolf being able to tell where Yujiro is going to try to hit because the move's movements are unnoticeable, or Nukite to thrust through Wolf's sword, or Peek-a-Boo to dodge everything Wolf tries, or the Quadruple Median Line Strike to blitz yet again, or use Right Cross of Confidence to slip Wolf's defense and land a mean right, or use Roppa Gaeshi to undo the suturing of the skull, or mitigate damage again with the Sanshin stance, or use Sangan to get a 2.55x reaction speed amp, now reacting (with DB) 10x faster than Wolf can move, or spam Seiken until one hits, or barrel into him with the Shikiri Stance, or Shodan him into oblivion, or just straight slap him, as one would still kill, or use the Soccer Ball Kick and score a goal with Wolf's head, or Spear Tackle him into paste, or since this isn't a stomp anymore, use Stomp, which is a 4x strength amp, or use Sunkei, which makes Yujiro's punches knockout punches at any range, or use a combo of the Sway Back to dodge an attack last minute only to follow with a Tackle and smash Wolf, or use the Telephone Punch and introduce Wolf's chin to his belly button, or use his Toe Use to strike Wolf's vitals while he's concerned with Yujiro's hands, knocking him out, or he can use the Triceratops Fist and blitz him, or he can use Vice Grip if he tries to grapple and grabs his body parts and then Yujiro holds it so tight that it explodes due to the blood restriction, making that body part useless, or just spam Windmill Punch?
TL;DR, Wolf doesn't win here
