Akira Otoishi

"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 featured in the fourth part of JoJo's Bizarre Adventure, Diamond is Unbreakable, specifically in the "Red Hot Chili Pepper" story arc.

Made a Stand user by Keicho Nijimura, Otoishi steals the Arrow from him and begins to battle the Joestar Group in order to drive them away or kill them then be able to commit his crimes in Morioh undisturbed. His Stand is the electricity based Red Hot Chili Pepper.

Appearance
Otoishi is a 19-year-old man with long, wavy, purple hair. A lightning-bolt-shaped scar (or tattoo considering its color) crosses the left of his face vertically, from his forehead over his left eye to his jaw.

He wears a dark jacket; the right sleeve having the words "AC" and left sleeve "DC" on them, along with a vest, tight pants, and boots. He also frequently wears an electric guitar with the designs varying between the  and the.

Personality
Otoishi is highly self-centered, using his newfound power to steal from various people and wreak havoc among the town, and even killing whoever gets in his way without hesitation. 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. Otoishi expresses himself through his guitar, such as channeling his anger at Josuke for breaking his pinky.

Josuke describes him as an intelligent coward that goes into hiding until he knows that he can beat or kill someone. While he is cautious, there are times when he slips up or becomes overconfident. For example, when he called Jotaro to try and get him to leave, he inadvertently mentioned he was a student. When confronting Josuke for the first time, Otoishi underestimated Josuke's power, later making the exact same mistake when he confronts Josuke a second time at the pier in person. Despite this, he has the capacity to learn from his mistakes, as proclaimed by himself.

Due to the nature of his Stand, he is confident but also intelligent enough to utilize its abilities to the maximum and is somewhat proficient at manipulation, evident through his battle with Okuyasu. However, while intelligent, he often fails to notice smaller details that could lead to his downfall as shown in his fight with Josuke. After being sent to prison, he seems to have reformed and is no longer causing trouble as shown in Thus Spoke Kishibe Rohan.

In Thus Spoke Kishibe Rohan Episode 2 and Eyes of Heaven, he claims to be a fan of Rohan's work.

Stand
Red Hot Chili Pepper is a small humanoid Stand which can travel through electrical currents and absorb electricity to empower itself. When powered up, it is a physically powerful Stand able to trade blows with the likes of Crazy Diamond but exhausts its energy quickly.

Music
 Guitar : Otoishi is a competent guitar player, and is notably able to compose a solo on the spot and use right-hand tapping. His ability to perform a solo is such that he can forcibly reset a broken pinky in the middle of playing.

Background
Otoishi 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, being fortunate enough to develop a Stand, naming it Red Hot Chili Pepper. Keicho then left him alone, but Akira developed his Stand to its full potential. At the same time, he used Red Hot Chili Pepper's ability to infiltrate any place connected to Morioh's power grid and steal objects as he pleased.

The Nijimura Brothers (10)
To further his rather self-centered goal, Otoishi uses his Stand to murder Keicho and forcefully wrest the Bow and Arrow from him.

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)
Otoishi phones Jotaro at his hotel, warning him to leave Morioh, adding that he killed Keicho, has the Bow and Arrow, and that he won't bother them if they don't bother him. Lashing out at Jotaro for deducing that he's a student, Otoishi has his Stand destroy 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. At one point, Akira shoots two rats in the fields.

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

In order to help discover Otoishi's whereabouts, Jotaro calls on Joseph Joestar in order to again make use of his Stand, Hermit Purple. However, Akira has hidden Red Hot Chili Pepper in Okuyasu Nijimura's motorcycle, allowing him to eavesdrop on Jotaro's revelation even if they meet in the middle of an empty field. Red Hot Chili Pepper appears and drives away, but Okuyasu teleports himself on the motorcycle. Red Hot Chili Pepper can easily evade The Hand's swipes, but Okuyasu was aiming at the motorcycle and destroys it, isolating Red Hot Chili Pepper in the middle of a field. A fight ensues between Red Hot Chili Pepper and Okuyasu as the rest of the heroes run to him. Eventually, Red Hot Chili Pepper runs out of juice and is depowered. However, Akira manages to goad Okuyasu into swiping at his Stand, opening the ground and uncovering a power line. This allows Chili Pepper to reabsorb enough energy to defeat Okuyasu and nearly kill him if not for Josuke's intervention.Akira then heads to the port with a toy plane so that Red Hot Chili Pepper can fly to the boat. He hides when Jotaro is present but as soon as the man leaves to join Joseph, Akira makes himself know to Josuke and Koichi who are standing guard at the port. Expressing his utter confidence by declaring he only needs his pinky to defeat Josuke, Akira is interrupted when Josuke breaks said pinky. Furious, Akira performs a guitar solo. Josuke attacks but Red Hot Chili Pepper exploits the drains under the pavement to attack Josuke from all angles. However, Josuke turns the concrete back into tar, and Red Hot Chili Pepper's presence causes bubble that allow the student to strike Red Hot Chili Pepper once. Otoishi decides to empower Chili Pepper with the entire city of Morioh's electrical supply, resulting in it receiving a massive boost in strength and speed and allowing it to overtake Crazy Diamond with little trouble. Josuke manages to trap the Stand in a rubber tire, but Chili Pepper punctures a hole. Otoishi's overconfidence is the reason for his defeat, as the tire's air pushed it into the ocean along with Chili Pepper, dismantling the Stand and bringing him to near-death.Even seemingly losing consciousness while standing up, Otoishi used a last-ditch effort to get himself onto the boat that Joseph is on, disguising himself as a Speedwagon Foundation crew member. He manages to enter Joseph's room, guarded by Okuyasu, but his plan is complicated when another Speedwagon Foundation staffer comes to warn Okuyasu and Joseph. Okuyasu doesn't understand the situation immediately, and Akira tries to accuse the other member of being the enemy. However, Okuyasu attacks and luckily hits Akira, taking him out.Otoishi 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 and put an end to him. Akira was intimidated and didn't cause any more trouble afterwards.

Otoishi later reveals to Jotaro that he had shot the rat Bug-Eaten, but hides the fact that he actually shot two rats (Bug-Eaten and Not Bug-Eaten).

Mutsu-kabe Hill
Otoishi 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.
