Akira Otoishi

Akira Otoishi is an antagonist from Part IV: Diamond is Unbreakable.

Diamond is Unbreakable
Akira was one of the many people Keicho Nijimura shot with the Bow and Arrow while trying to find a stand user capable of killing his mutated father. Akira was one the many lucky ones to develop a stand, after which he became interested in stands and their creation. To further this goal, he forcefully took the Bow and Arrow from Keicho, leading to Keicho's death. From there on, he watched and tormented several people, among them Josuke Higashikata while trying to improve in the use of his guitar skills. He also shot Mushikui and Mushikuidenai with the Arrow.

The theft of the Bow and Arrow causes Jotaro Kujo to mark him as a threat and search for a way to find the location of his person, as his stand allowed him to interact with others from a distance via electricity. To accomplish this end, Jotaro called on Joseph Joestar. Immediately Akira discovered their plans, which lead to a short skirmish between Okuyasu Nijimura, in which he discovered that Red Hot Chili Peppers had a time limit, as when not reserving enough electricity it grows weaker. Using this to his advantage, Okuyasu savagely beat the stand before he accidentally opened a hole within the floor which lead to a power line, which Akira used to reabsorb enough energy to defeat Okuyasu. During their next confrontation, Akira personally showed up to kill Joseph. He believed Josuke to be an easy match, underestimating the youth which lead him to his defeat. Even after this Akira used his last power to teleport himself to the boat that Joseph was on, disguising himself as a Speedwagon Foundation operator. Okuyasu, acting as the bodyguard for Joseph saw this and prepared to attack him but Akira confused him by saying the other SPW Foundation operator was the real Akira. Okuyasu, not used to brainwork, decided to hit both and luckily struck Akira first.

He was later put on trial with a sentence of three years behind bars with no bail or parole for the things he had stolen. It was there that Jotaro confronted him saying that if he tried to escape, he and Josuke would hunt him down to the ends of the earth. He reveals to them that he shot the rat Mushikui, but hides the fact that he actually shot two rats.

Akira, newly released from prison, asks for Rohan's autograph along with Tamami Kobayashi, claiming to be a big fan of his. Both are harshly rebuked by Rohan's editor Kagamari Minoru, who tells them that Rohan is busy at the moment, but Rohan, in turn, scolds his editor for treating him like a "slow manga-ka who can't sign autographs" before signing autographs for the two of them with coffee using a special dripping technique.
