Anime characters appear in all shapes and sizes. They also appear under a variety of names.

This list is going to contain a list of anime characters that start with the letter I. They will be sorted alphabetically by the names they are known best, whether it is their first name, last name, or their nicknames.

He first appears after Byakuya Kuchiki confirms Renji and Rukia that the latter has been executed.

Gin, accompanied by Kenpachi Zaraki, asks Byakuya how he manages to remain so calm as his sister’s death approaches. As a fight between Byakuya and Zaraki was about to begin, Gin comically ends it by wrapping Zaraki in his haori and then pulling him like a sled, his sealed Zanpakutō is a wakizashi. Its power lies in the fact that it can stretch a length of one hundred blades in shikai, and 13 km in Bankai.

As one of the Hashira, he is one of the most powerful swordsmen in the entire organization. Obanai ponders every step he takes and tries not to panic in any situation. He starts an attack when he recognizes what his opponent is capable of. Such a lead often allows him to win.

Iguro is able to bend his sword at all possible angles, although his sword is exactly the same as that of other people. His sword can slide into small slits like a snake. Obanai, who was always partially blind in his right eye, developed a fighting technique using his Kaburamaru snake. Kaburamaru is able to read enemy attacks and transmit this information to Obanai.

InuYasha (InuYasha)

InuYasha is the main character of the story. He is a hanyô, a hybrid being half-man, half-demon, with a human appearance of about fifteen years.

But there is a condition, that of not having anything to do with the shinigami anymore, but he broke the contract on the pretext that Ichigo was only a “substitute shinigami”. Ryuken will then say that if Ishida wishes to die or live, this choice was up to him. Apparently, he knows Ichigo’s father very well.

Ishida, Sōken (Bleach)

Sōken Ishida is Uryū’s grandfather and teacher and it seems he was the one who raised him. He died defending himself against five hollows that had attacked him. The shinigami arrived long after his death and that’s one of the reasons why Uryū hates them (In the anime he says that the shinigami’s tacky uniforms are another reason.) Uryū later finds out that the shinigami purposely delayed their intervention because they captured his grandfather’s soul to experiment on until it was destroyed (this is 12th Division Captain Mayuri Kurotsuchi, who performed these experiments).

Ishida, Uryū (Bleach)

Uryū Ishida is a Quincy, descended from a line of hollow hunters. At the beginning of the series, he had a certain rivalry with the other main characters, since he had a deep grudge against all the shinigami, including Ichigo, but as the story progresses they become friends. However, even being Ichigo’s friend, he cannot stop competing against him.

It was she, unknowingly, who caused the liberation of Marik’s dark side, bringing him for once into the outside world and for this, she took on the great burden of saving him. She relied on Odion for her to contain that part of her brother, so she helped Pegasus hide the three Egyptian God cards, although Malik was able to retrieve the Winged Dragon of Ra and Slifer the Sky Dragon.
