The Unfought: He is one of the few major characters that Baki has never actually fought.

Taught by Experience: His strength and expertise comes from his 70+ years of experience.Retired Monster: Gouki was an assassin in the past.Pyrrhic Victory: He considers his victory over Kosho this, given that he damaged his glass eye, which is expensive.Pintsized Powerhouse: He's very short, yet capable of dealing massive amounts of damage, and even dragging Oliva around using his Aiki.No Celebrities Were Harmed: Based off of real-life aikido master and the founder of Yoshinkan style of aikido Gozo Shioda.Mundane Made Awesome: His Aiki, a real principle in martial arts denoting the ability to feel and control the opponent's center of gravity as well as one's own, is treated as a borderline superpower, as he is able to toss around and even drag people much bigger than he is using it.Manchild: He even acknowledges it, discussing the absurdity of a frail retirement age man like himself going out and picking street fights for laughs.If Shibukawa is the one attacking recklessly, then he's entirely vulnerable to his opponent's punches. As his match with Doppo shows, Shibukawa's aiki is formidable but almost entirely defensive, since it requires the enemy to throw attacks that can be redirected.Jack also defeats him by biting his arms as there is no real way to redirect the teeth sinking in. His aikido is good against people he can redirect their attack against themselves like Oliva but against a poison user or a swordsman it doesn't help much as even the smallest contact will either poison or cut him.Imminent Danger Clue: He mentally envisions some kind of absurd obstacle, like a pit of fire or an impossibly huge door, if he is about to walk in to a fight against a superior opponent.Handicapped Badass: He has a glass eye but is still a precise and strong fighter.Glass Cannon: He isn't as strong and durable as the The Ogre, Hanayama or even the karate master Doppo himself, but Shibukawa can make still someone like Oliva keel over on his knee making him feel his own weight.For the Lulz: He became a martial artist and assassin for the giggles and ecstasy of it all.He challenged a sumo wrestler six times his size to belt-wrestle one another and is actually shocked he was thrown by sheer power. He knows exactly when a fight may end in his death, yet still go through and he won't use his more offensive techniques because he wants to prove his aiki is perfect. Fatal Flaw: Like most masters, he has a bad case of pride and likes to test his limits."Eureka!" Moment: Shibukawa settled out to found his own dojo after a spar where he resisted his retirement age Aikido master's Killing Intent and made him draw and swing a sword at him.He also breaks the muscleman's arm after being flipped by him. Did You Just Punch Out Cthulhu?: He manages to drag around Biscuit Oliva, one of the strongest characters in the series, by his finger, although he doesn't defeat him.Defeat Means Respect: Grew to respect Doppo for being the first opponent in a while to make him feel real fear in a fight.Defeat Means Friendship: After beating Doppo in the Maximum Tournament, they become good friends.Cool Old Guy: A nice old man that teaches the police force judo in his off time and can overpower the likes of Oliva.Combat Pragmatist: Shibukawa has shown she's not above dirty tactics, like spitting water into his opponents eye socket to try and drown them.He's still scrawny compared to the rest of the cast though. Clark Kent Outfit: He is actually pretty well built under his kimono, but for decency he prefers keeping it on.Bunny-Ears Lawyer: He looks and acts like a wacky old man but his aikido and jujitsu are master level.Blood Knight: In his youth, he joined the military and became an assassin to fulfill his desire for fighting.Only Yujiro has ever successfully do the same. The Ace: Shibukawa is regarded as an expert in aiki, with many noting that anyone else trying to use aiki like he can is basically impossible.A World War 2 veteran with a penchant for mischief and a consumate traditionalist, Gouki prefers to confound his opponents into attacking first, so he can take advantage of their lack of respect. An elderly Jujutsu master who Baki encounters in the Maximum Tournament.
