Rusaburō Enkōgawa

, commonly called, is introduced during the anime's The New Captain Shūsuke Amagai arc.

Appearance
Enryu is a muscular man with a small mohawk in the shape of a lightning bolt. Under his standard Shinigami uniform is a light purple garment. He also wears large sunglasses and can often be seen having strange looks on his face.

Personality
During the course of the arc, Enryu doesn't speak at all. He instead uses sign language that only Kenryu understands. And though it was plausible he was mute, when protecting Rurichiyo from Shusuke, he had a high pitched voice that he was very self-conscious about.

The New Captain Shusuke Amagai Arc
When he first appears in Karakura Town, he, Kenryū, and Rurichiyo are left without gigais. Rurichiyo wanders away from her guards and pesters Ichigo to get her food. He and Kenryu then appear and take Rurichiyo away, as hoards of hollows are approaching. Ichigo releases his Bankai and destroys the creatures, impressing them all. The next day, Ichigo discovers they are living next to him, as well as going to his school. Ichigo proceeds to ask what they are doing here, but all of them refuse to answer.

It isnt until Ichigo defeats one of the assassins that Rurichiyo's past as the head of the Kasumiōji Clan is revealed. Kenryu and Enryu, being her bodyguards, enlists Ichigo's help in protecting her. Later, at dinner, Kenryu angers Rurichiyo and she storms out of the house. She goes to the lake where she and Orihime Inoue are attacked by another assassin. Kenryu and Enryu once again leave the fighting to Ichigo.

After Rurichiyo enters her family compound, she agrees to marry Shū Kannogi in order to keep Kumoi in line. Enryu, Kenryu, Ichigo and Rukia then follow her and are attacked by Soifon's patrol corps. Enryu releases his zanpakuto and destroys the building, giving them time to reach Shu. Rurichiyo then attacks, revealing herself to be an imposter. Enryu and Kenryu are captured, but the others escape with Shu.

The two are returned to the Kasumioji clan, at Yamamoto's order. Ichigo then enlists the help of the 3rd Division captian, Shusuke Amagai, to save Rurichiyo. They succeed, but Shusuke is revealed to be the true villain, and attempts to kill Rurichiyo and Yamamoto together. Both Enryu and Kenryu release their zanpakuto but dont seem to faze the captain. Luckily, the Vizard Ichigo defeats Shusuke, and Rurichiyo is free to go home. Enryu and Kenryu follow her.

Kenryu and Rurichiyo got into a dispute over whether or not to hold a soccer tournament in the Seiretei. In response to Kenryu's disapproval, Rurichiyo runs away to the human world. Kenryu and Enryu follow and Kenryu enlists Uryu's help in persuading the princess. Their plan would have worked, that is, if Kenryu hadn't insulted Rurichiyo. They then hold a Kemari game to settle the argument, and everyone participates.

Enryu chooses to be on Rurihchiyo's team, which leads Kenryu to call him a traitor. With Urahara's barrier constructed, Kenryu kicks off. Uryu, using his Quincy arrows, stops Ichigo from getting the ball, so Enryu releases his Zanpakuto and traps the former. Rukia uses her Second Dance, Hakuren to fend off Ichigo, but he escapes and is cornered by Ikkaku. With them distracted, the match is down to Rurichiyo and Kenryu. A hollow attacks because they released too much Reiatsu and Rurichiyo drops the ball. Luckily, Shu arrives and convinces Kenryu that they should hold the tournament, as the commoners have been asking for it. With that in mind, they return home.

Zanpakutō

The two fists are attached to a large chain which corresponds to each of his hands. The chain follows from one fist up his arm around his neck and down his other arm to the corresponding fist. Enryu possesses a Defense-Type Zanpakutō.
