Tetsuzaemon Iba

is the captain of the 7th Division of the Gotei 13. His lieutenant is Rindō Atau. He was formerly the 7th Division's lieutenant under Captain Sajin Komamura.

Appearance
Iba has a distinctive hair cut and wears black sunglasses with his standard Shinigami uniform. He collects sunglasses, his main source being, the same shop where fellow Lieutenant Renji Abarai purchases his goggles. He also smokes and carries his Zanpakutō as a small blade inside his uniform. He has a large tattoo on his back consisting of a cat on fire and the kanji shōfuku (inviting luck). These features, plus his informal style of speech, are all strongly reminiscent of a typical yakuza. Seventeen months after Aizen's defeat, Iba has a fuller moustache and a new scar above his left eye. His hair is also more shaven, with three hairless lines running through it.

Ten years after Yhwach's defeat, Iba sports a crescent-shaped scar around the outside of his right eye and has a pompadour-like hairstyle.

Personality
Iba enjoys fighting, like members of the 11th Division, but unlike many of them, puts his loyalty to his Division above his desire to fight and is not above retreating from battle. Iba tells Ikkaku Madarame that frontal assaults that lead to defeat are meaningless and that he must win however he fights. Iba is very loyal to his captain, though in the week after Kaname Tōsen’s betrayal, he spent a lot of time at the 11th Division headquarters in order to give his captain some space. Preceding their fight, Ikkaku mentions that Iba has become cockier since he left the 11th Division to become a lieutenant. Iba also seems to have recurring stomach problems, which he notes with shame on a few occasions. He and Ikkaku seem to have something of a working relationship, though it consists mainly of them dueling, drinking sake, then dueling again to see who has to get more.

He is also both extremely loyal and decisive, as seen during his encounter with Choe Neng Poww. With Captain Komamura having been knocked out of the battlefield, Iba grabs the injured Ikkaku (his former squad mate) and drags him away from Poww, refusing to abandon Ikkaku despite Ikkaku's protests and reasoning that Iba has a better chance of surviving if Iba would just let him be. When Komamura steps up to counter the Arrancar's attack, he tells Iba not to stray from his side and Iba immediately complied.

The macho-ist lieutenant is president of the Shinigami Men's Association and forces all members to dress like him at meetings, including wearing their uniforms and sunglasses in similar manners to his own. His meetings consistently have him as the butt of the jokes of the Shinigami Women's Association, consistently at odds with their vice-president Nanao Ise on their actions and manners. Iba is frequently in the company of the other male lieutenants and officers. He seems to share their penchant for perverted things related to the female Shinigami.

Iba speaks in a Hiroshima dialect and wants to spread its knowledge more, therefore at some point in the past he started a course on his own expense, but had to close it down due to lack of attendance. He currently pens an article in Seireitei Communication "Guys Corner" titled "The Hiroshima Dialect Seminar Brimming with Macho-ism." His favorite food is okonomiyaki, but only if it is done in Hiroshima style, while he detests the one prepared in Osaka style.

History
Iba was originally the fourth seat of the 11th Division and Ikkaku Madarame's superior, but transferred to the 7th Division because getting promoted to lieutenant in the 11th Division was more difficult, if not impossible. It is rumored that he wished to become a lieutenant not out of personal ambition, but to please his mother, Chikane Iba. As a result, his former compatriots in the 11th Division look down upon him, as they deem the other divisions weaker than they are. In spite of this, he has a habit of hanging around their division's headquarters. Despite having left the 11th Division, it is clear he still enjoys a good fight, and during his duels with Ikkaku reveals a maniacal grin much like his sparring partner.

Soul Society Arc
Iba attends the Lieutenants meeting with Renji and the other when the Ryoka invade the Seireitei. Along with his captain, he visits Fourth Division compound with Kaname Tōsen to pay their respects to the deceased Sōsuke Aizen. The morning of Rukia Kuchiki's execution, he uses to enter the room and apologize to his captain for his tardiness. He invents a story to justify the delay, though the actual reason is because he knows that Komamura is unsure of the decision, and wants to give him time to decide. Komamura sees right through this, but lets it go, understanding it as an act of compassion.

Soon after that, Komamura and Tōsen take their lieutenants, Iba and Shūhei Hisagi, to challenge Kenpachi Zaraki because he freed Uryū, Chad, and Ganju from their cell with Orihime's direction and is leading them to Sōkyoku to stop the execution. Yachiru takes control and starts to lead the group ahead to Sōkyoku when the four Shinigami confront them. After Kenpachi claims he can take on all four, Yumichika Ayasegawa and Ikkaku Madarame complain that they want some action, and so Kenpachi lets them have Shūhei and Iba.

Their fight ends up with the two sharing a bottle of sake. While they are resting from their fight, Ikkaku unwittingly reveals that Iba mastered all elements of Shinigami combat in order to become lieutenant. When Ikkaku mentions that he sounds unhappy, Iba denies it. When Ikkaku goes on to say that Iba has become lieutenant for his mother, Iba denies it again. Iba abruptly changes the subject by pointing out that they've run out of sake. After that they play rock-paper-scissors to see who gets the higher ground. Iba wins the rock-paper-scissors match, and before they begin both of them wonder who Byakuya Kuchiki is fighting on Sōkyoku Hill. Ikkaku states that it is Ichigo. Iba admits that he’d like to fight Ichigo, and Ikkaku tells him he has the spirit of the Eleventh Division. They decide that the loser of the match gets more sake while the winner rests, but remind each other that if either lets up, the other will die. However, the match is interrupted by Isane’s report on Aizen, Tōsen, and Ichimaru’s betrayal.

He later appears along with a majority of the other Shinigami at Sōkyoku Hill to capture Aizen, Gin, and Tōsen. When a beam of light crashes down on Aizen and starts taking him away, Iba attempts to attack and stop him. However, he is stopped by Genryūsai Shigekuni Yamamoto, who tells Iba that the beam of light is called Negacion and that the Menos use it to rescue their comrades. He continues to explain that the area inside the light is a completely separate dimension impenetrable from the outside and that as soon as the light came down Aizen became beyond their reach.

Later, when Iba is at the Eleventh Division headquarters, he is hanging out with Yumichika, who notes, with some irritation, that it is awfully loud because of Ikkaku, Ichigo, and Kenpachi. Iba says it has been like that since Ichigo started hanging out with the Eleventh, but it is better than quiet. Yumichika asks why he is hanging out there, and Iba says that Komamura wants to be alone.

Fake Karakura Town Arc
When Aizen, along with his top three Espada and their Fracción arrive to attack the Fake Karakura Town, he along with his captain are among the Shinigami who defend it. He asks his captain if they should take down Aizen or the Espada first. Sajin replied that they should take out the Espada first.

When Poww defeats Ikkaku Madarame, Iba's Captain Sajin Komamura saves Ikkaku. Komamura calls Iba, and Iba throws some rod items to stop the Fake Karakura from returning to normal. Iba realizes that Poww is almost twice the size of his captain, but when Poww releases his Zanpakutō, Iba is shocked. Komamura tells him to stay behind him as he releases his Bankai and defeats the Fracción. After the fight, Iba reveals that he knows about Ikkaku's Bankai, and admonishes him for allowing the pillar to be destroyed because of his selfish desire not to reveal his true strength, and believing that because he is replaceable, it does not matter if he dies. Iba then tells Ikkaku that if he wants to do things his way, he must become stronger and win, even at the cost of his life.

After the fight begins between Hisagi and Ayon, Iba momentarily steps in to attempt a surprise attack from Ayon's rear. He initially assumes that his movements have been successful in surprising the creature as it does not react, however, he is mistaken and he is suddenly blasted away by Ayon's Cero, after it reveals it's eye's true location.

Along with the other injured Shinigami, Iba is treated by Izuru Kira, while Komamura stands by the barrier, after Yamamoto easily defeated Ayon.

After the captains are able to outsmart Aizen and Hitsugaya stabs him from behind, Kira yells out that the captains have finally won. Iba tells him that he should look happier at this fact. All of a sudden, Momo gets up and starts to walk away and Iba and Kira ask her where she's going, but she doesn't answer. Momo then swings her Zanpakutō at them. The two of them are cut down as Momo reveals herself as Aizen and that they were under his complete hypnosis the entire time.

The Thousand-Year Blood War arc
While the captains are in a meeting, the lieutenants gather and discuss the situation with the Wandenreich and recent disappearances of Hollows and Rukongai residents. Iba listens as Izuru deduces that Shinigami were likely involved in the disappearance of the Rukongai denizens. When the Sternritter invade Seireitei, he along with his Captain head out to deal with the invaders. After heading out, Captain Komamura soon confronts Bambietta Basterbine, with Tetsuzaemon standing close by. He listens as Komamura explains that observing how the Wandenreich seal a Bankai and devising a way to counter this will be the key to the battle. Because of this, he is instructed to help him find a way to counter the Wandenreich's technique of sealing away Bankai. However, to Tetsuzaemon's surprise, Komamura's Bankai is stolen rather than sealed.

Some point later, he and the rest of the 7th Division are found to be lying on the ground from having difficulty fighting against Bambietta Basterbine. When Captain-Commander Yamamoto is detected to be heading to the front lines, Komamura orders Iba and the rest of the division to stand up. Rallied by Komamura's words on how shameful it is for the members for the Gotei 13 to be lying down while the Captain-Commander is at the front lines, Iba and the other Shinigami quickly rise up.

Some time after the Wandenreich assault ends, Iba accompanies Komamura to a cave outside of Seireitei. While his captain ventures inside, Iba exercises while he awaits his captain's return. Later Tetsuzaemon bears witness to the swift and complete invasion of Soul Society by the Wandenreich.

After Komamura's battle with Bambietta Basterbine ends, Iba goes to his captain's location. He picks up his captain, who is now fully animal after his Humanization Technique expired. Iba then tells Komamura that they are going to defeat Yhwach and avenge Genryūsai Shigekuni Yamamoto.

Some time after Yhwach's defeat at the hands of Ichigo Kurosaki, Iba was promoted to the position of captain of the 7th Division. Ten years after the war, when the cleanup of Seireitei was nearing its end, Iba was training with some of his subordinates atop a cliff-side training ground. He jumped from the cliff in order to greet Captain Hitsugaya and Lieutenant Matsumoto, landing on his feet and placing a noticeable dent in the ground. After Hitsugaya makes an off-handed compliment about his work ethic, Iba replies that he still has plenty of training to undergo before his body is to be that of a captain's. Shortly after, Iba is present at the First Division's barracks for the promotion ceremony of Rukia Kuchiki to the position of captain of the Thirteenth Division.

 * (To Ikkaku Madarame) "I wasn't a do-it-all guy in the beginning, but instead of focusing on one thing, being more well-rounded means a better chance of promotion to lieutenant. Since my goal was to become a lieutenant, I decided to be a do-it-all guy."

Now, if you want to get yourself killed concealing that power, that is your choice. However, you should never ignore orders for such a reason!

Even if it means crushing your own wishes and your pride, you must enforce those orders with every fiber in your body!"
