Eyes of Heaven/Akira Otoishi

Otoishi was confirmed for the game along with Yoshikage Kira. Otoishi is of the Stand User Style, but more specifically is he a Mode User. The player can switch control between Otoishi and Red Hot Chili Pepper to alter the character's abilities, with Stand Mode being the more powerful. The Power Gauge, redubbed the Electric Gauge, makes a return as well.

Moveset

 * Style Action - Red Hot Chili Pepper: Control is switched between Otoishi (Host Mode) and Red Hot Chili Pepper (Stand Mode). While in Stand Mode, Chili Pepper has access to all of its skills. Damage dealt to the Stand is reflected in Otoishi, and any attack that delivers a knockdown will automatically and forcibly disable Stand Mode. Chili Pepper can interact with certain stage objects to transfer itself to specific points represented by anchor icons. This allows for quick escapes and inversely can be used to get closer to the opponent just as quickly. The stage objects themselves don't need to be electrical by nature, as Chili Pepper can travel between objects such as suits of armor and even flame lanterns. Unlike other Stand Mode Users, Otoishi's stamina gauge does not deplete while in Stand Mode; this is due to the fact that use of Chili Pepper is already tied to the Electric Gauge. However, this also means that Otoishi can theoretically remain in Stand Mode indefinitely so long as Chili Pepper has an external source of power always available.
 * Rule - Electric Gauge: On the right side of Otoishi's health gauge shows a two-meter gauge as well as a Level indicator (LV), its power constantly draining while in Stand Mode and being consumed in amounts whenever he uses skills. The Electric Gauge has five levels, ranging from Level 0 to Level MAX; each third of the first gauge raises Chili Pepper to the next level, enhancing the Stand's overall performance. Depending on the amount in the Electric Gauge, Chili Pepper's movement speed, attack speed, and attack strength will be enhanced, among other effects. If it is completely empty (Level 0), Otoishi is unable to use any skills or moves involving Chili Pepper, leaving him with choice few skills and his aerial Powerful Attack (a diving knee); If the Electric Gauge is filled past its first meter, Otoishi enters "Level MAX", further increasing the damage and speed of his skills, with Chili Pepper visually becoming brighter as more sparks and electric crackles come off of it.
 * Charge: Only available in Host Mode. Otoishi pulls out a small amp, allowing Chili Pepper to siphon off it and replenish the Electric Gauge.
 * I feel great, thanks to you.: When either Otoishi or Chili Pepper stand near an electricity-based stage object (e.g. lampposts and other light fixtures, Yukako Yamagishi's electric chair at Boing-Boing Cape, etc), the Stand can instantly fill the Electric Gauge by a whole meter by interacting with it. In the case of the electric chair, simply coming into contact with it while it's live will do so.
 * Right Hand Rockout: Only available in Host Mode. Otoishi plays a guitar solo as multi-colored spotlights appear above him out of nowhere. This consumes Otoishi's stamina to slowly fill the Dual Heat Gauge up to roughly 2/5ths of a stock if it completes without him stopping or an opponent interrupting, with full stamina allowing a complete solo. It is also a skill that Otoishi can still perform at Level 0, since it does not involve Chili Pepper.
 * Spitfire: Only available in Stand Mode. While airborne, Chili Pepper can take out and rides a small RC airplane, quickly carrying it through the air with a slow descent at the cost of draining the Electric Gauge faster. The higher the Electric Gauge level, the faster the Stand will fly and the sharper it can turn. The skill can be canceled with a Normal Attack.
 * You're the one who moved!: Chili Pepper delivers a fast punch that forcibly faces opponents away from it, forcibly disabling their lock-on and easily allowing for a Backstab to follow. The higher the Electric Gauge level, the faster the skill executes and the faster Chili Pepper can take action afterward, the skill will also receive damage boosts and Guard Break power accordingly; At Level 2 or higher, Otoishi himself is invincible on activation, and the duration of said invincibility is determined by the Electric Gauge level. At Level 3 or higher, Chili Pepper can seamlessly combo from the skill.
 * This Stand Power... It's as explosive as a jet engine...: Chili Pepper rushes forward in a flurry of 13 flashy punches, with the final hit sending opponents flying. The higher the Electric Gauge level, the faster the skill executes, the more hits and therefore damage is dealt, and the faster Chili Pepper can take action afterward; At Level MAX, Chili Pepper adds 15 extra punches, is capable of teleporting a moderate distance forward before performing the attack which increases the skill's effective range, and Otoishi himself is invincible on activation.
 * Time to get electric, baby!: Only available in Stand Mode. Chili Pepper covers itself in electricity and charges forward. If it connects, it turns the opponent into electricity and drags them into the ground, coming out of any specific locations around the stage to send them high into the air, randomly-selected. The higher the Electric Gauge level, the faster the skill executes and the faster Chili Pepper can take action afterward, the skill will also receive damage boosts and Guard Break power accordingly; At Level 3 or higher, Chili Pepper's charging attack gains some homing capabilities, and Otoishi himself is invincible on activation.
 * EX - This Stand Power... It's as explosive as a jet engine...: The skill does not consume Electric Gauge power, performs the Level MAX version by default, and can even be used at Level 0. The final hit knocks opponents to the ground hard enough for them to bounce.
 * EX - Time to get electric, baby!: The skill does not consume Electric Gauge power and performs the Level MAX version by default.
 * Dual Heat Attack - You wanna get nuts?! Let's get nuts!: Identical to its performance in All-Star Battle, though executes faster for the sake of brevity.

In Story Mode, Otoishi instead is an ally character, similar to his current status in canon spin-off of Rohan Kishibe series, first seen brainwashed by black aura created from Heaven Ascension DIO.

He is partnered with a revived Shigekiyo Yangu, until they are defeated and saved from DIO's control by Jotaro with a Saint Corpse Part during the second encounter. Once recovered from the brainwashed state, Okuyasu asks a surprised Otoishi how it feels to be one of the good guys now, while Otoishi is still frightened of Okuyasu's presence, thinking he wanted to get revenge for murdering his brother Keicho. However, he was relieved to have conversation changed to seeing Shigechi well again, but Otoishi is interrupted by the presence of the brainwashed Weather Report (who also died and was revived like Shigechi and most of the other deceased allies), whom was later defeated by Jolyne and Anasui, and saved using the corpse part.

As DIO (in his Heaven Ascension form) sends the Joestars (except for Jolyne and Jotaro who fight DIO in Cairo) into his traps, creating illusionary doubles of their brainwashed allies several times until succumbing to the control of the dark aura and giving the corpse to DIO. The Joestars and their allies' souls are absorbed into DIO to increase his power tenfold. Among the souls absorbed is Otoishi.

Otoishi's current status in a new timeline remains unknown, as he may be a reformed criminal, or may have reverted to his past ways. It is also unknown if it altered his murder of Keicho Nijimura or his giving of a Stand to Bug-Eaten and the unnamed rat.

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".
