Akira Otoishi

"Oh! The name's Akira Otoishi, 19 years old! Don't mind this guitar I have right here. My dreams is to be like Jimi Hendrix or Jeff Beck. To be an ultra super guitarist and live life hard and fast...that's why I'm keeping this baby with me at all times. In the near future, with this baby right here, I'm gonna BLOW THE WHOLE WORLD AWAY!"

- -Akira Otoishi

Akira Otoishi (音石 明) is an antagonist in Diamond Is Unbreakable; featuring centrally in the arc Red Hot Chili Pepper.

Akira steals the Arrow from Keicho; continuing a selfish terror on Morioh and the allies until they battle at the town's docks.

Appearance
Akira is a 19-year-old man with long, wavy hair. A lightning-bolt-shaped scar crosses the left of his face vertically, from his forehead over his left eye to his jaw.

He wears a dark jacket, whichs right sleeve has words "AC" and left "DC" on them, with a vest, tight pants, and boots. He also frequently wears an electric guitar resembling the Fender Telecaster.

Personality
Akira is highly self-centered. He is dedicated to his craft as a musician; wishing also for recognition or fame as a Rock star. After he is released from prison, he continues to pursue this goal.

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 of the many lucky ones to develop a Stand, after which he became interested in Stands and their creation.

The Nijimura Brothers (10)
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.

Koichi Hirose (Echoes) (1)
Akira phones Jotaro at his hotel, warning him to leave Morioh, adding that he killed Keicho, he has the Bow and Arrow, and that he won't bother them if they don't bother him, just before he destroys the phone.

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 allows him to interact with others from a distance via electricity.

Red Hot Chili Pepper
Akira sends his Stand through Josuke's TV, fighting him in order to test his strength in preparation for the event of a confrontation with Jotaro.

To help discover Akira's wherabouts, Jotaro calls on Joseph Joestar in order to again make use of his Stand, Hermit Purple. Immediately, Akira discovered their plans, which led to a short skirmish with Okuyasu Nijimura, in which he discovered that Red Hot Chili Pepper 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 led 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 Bug-Eaten, but hides the fact that he actually shot two rats (Bug-Eaten and an unnamed rat).

Mutsu-kabe Hill
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 Minoru Kagamari, who tells them that Rohan is busy at the moment, but Rohan, in turn, scolds his editor for treating him like a "slow mangaka who can't sign autographs" before signing autographs for the two of them with coffee using a special dripping technique.

All-Star Battle (PS3)
Akira is featured as a playable character in All-Star Battle. In the Morioh City stage, when the stage hazard activates and puddles around the area are shocked, his exclusive electricity gauge is replenished to max if he is hit.

Eyes of Heaven (PS3/PS4)
Akira was confirmed for the game along with Yoshikage Kira.

In this game, he instead is an ally character, similar to his current status in canon spin-off of Rohan Kishibe series, as seen on the brainwashed black aura by Heaven Ascension DIO on him.

He is partnered with a revived Shigekiyo Yangu, until they are defeated and recovered by Jotaro with a Saint Corpse Parts during the second encounter. Once recovered from the brainwash state, Okuyasu ask a surprised Otoishi on how he feels to be one of good guys now, while Otoishi also frighten of Okuyasu's presence, thinking he want to have revenge again for murdering his brother Keicho. However, the relieved conversation of seeing Shigechi well, but with Otoishi is interrupted by the second presence of the brainwashed Weather Report (who also died and revived like Shigechi and most of the dead allies), whom later being defeated by Jolyne and Anasui, and recovered by Jotaro through using the corpse part.

As DIO (in his Heaven Ascension form) sends the Joestars (except for Jolyne and Jotaro who still DIO in Cairo) into his traps, such as creating an illusion of their brainwashed allies many times until being succumbed by the dark aura into leaving the corpse, the Joestars and their allies' souls to be absorbed into DIO to extend his power to kill Jotaro and Jolyne left, Otoishi and his newfound allies are amongs the souls DIO absorbed.

Otoishi's current status in a new timeline remained unknown if he is still a criminal as always or fully reform himself.

Tournament
He is paired with Enrico Pucci in the Eyes of Heaven tournament, but was eliminated in the preliminaries by Weather Report and "Kosaku Kawajiri".

Trivia

 * In Thus Spoke Rohan Kishibe Episode 2, he claims to be a fan of Rohan's work.
 * In All-Star Battle, if Akira is K.O.ed in the last round via any attack that doesn't down him, he will remain standing but in a hunched over position, mirroring the style of his defeat to Josuke in the story.
