GioGio's Bizarre Adventure (PS2)

Alongside Bruno's gang

Koichi was planned to be in the GioGio PS2 game, likely as a playable character as there are beta pictures of him appearing in the game (such as one of him appearing with the main characters of Vento Aureo and in another one looking for Giorno and his stolen luggage). However, for unknown reasons Koichi was removed from the game, with no trace of him even in the game's Gallery Mode (unlike other characters, such as Risotto Nero or Leaky-Eye Luca, who do not appear in Story Mode but have viewable characters models regardless).

In canon Vento Aureo, Koichi has a confrontation with Giorno over his stolen items and later helps him fight against Black Sabbath. As he was absent from the game, the Story Mode begins with the narrative skipping to Giorno on the tram being confronted by Bucciarati in Chapter 1, and in Chapter 3, Giorno fights Black Sabbath by himself.

[edit]

All-Star Battle (PS3)

Koichi makes his playable debut in the PS3 game and was confirmed along with Akira Otoshi. Koichi is voiced by Romi Park, who previously voiced Giorno Giovanna and Gold Experience Requiem in the aforementioned PS2 GioGio game.

As one of the majority of playable characters with the "Stand" Style, Koichi can turn Echoes ACT3 on/off, changing movesets, as well as having access to the Stand Rush ability returning from the Capcom game, being able to attack in conjunction with his Stand. Along with Enrico Pucci, Kosaku-Kira, Johnny Joestar, Hol Horse, and Giorno Giovanna, Koichi is a character who can utilize more than one Stand during a match as part of his moveset. In gameplay, Koichi uses all three forms of Echoes as part of his moveset, unlike Johnny or Pucci, who need to evolve their Stands during combat. Koichi has 900 HP.

Command List

During a fight, Koichi can use several different abilities that were featured in Diamond is Unbreakable.

Style/Specials/Etc

Stand On/Off

ON GROUND

Koichi can summon or dismiss Echoes ACT3, shifting his available abilities.

Enough!

+ ON GROUND

Koichi lunges forward and swings a fist with all his might. If the punch connects, the opponent is knocked off their feet. This skill is a middle attack that cannot be blocked crouching. A command normal that can chain into Koichi's skills. (Comboable)

3 Freeze

Passive

Koichi's HHA, GHA, or his "S-H-I-T" special skill will inflict 3 Freeze upon connecting with the opponent.
Under its effects, the opponent is made heavier due to ACT3's unique ability, and forced into a constant crouch. This results in them being unable to dash, jump, or utilize special skills, HHA, or GHA.
While the effect cannot be broken manually (hitting Koichi or gaining distance does nothing), it has a relatively short duration, slightly altered based on the attack that generated it. Although the opponent is forced into a crouching state, they are still able to freely guard against all Middle attacks and will automatically stand to do so when defending.

Special Moves (Stand Off)

I'll never forgive you!

+ // ON GROUND

Koichi summons ACT1 to fly forward a moderate distance and assault the opponent with loud and disruptive SFX. This move has a follow-up. (Flash Cancel comboable)

Cicada's cry etched in stone

(During "I'll never forgive you!") + // ON GROUND

ACT1 increases the number and volume of its SFX, causing the opponent to take damage multiple times until they collapse from the noise. (Comboable)

Sizzle!

+ // ON GROUND

ACT2 throws its tail end as a projectile SFX that arcs. The attack button inputted determines the projectile's arc and distance thrown. If it hits the opponent, they will catch fire and gradually lose health over time for a few seconds. This move functions as an anti-air. (Flash Cancel comboable)

Kaboom!

+ // ON GROUND

A counter. Koichi boldly crosses his arms and side-glares at the opponent. If they strike him during that moment, SFX by ACT2 will reveal itself on Koichi and produce a forceful explosion, blowing them back.

Boing!

+ // ON GROUND TRAP

ACT2 slaps an SFX on the ground in front of Koichi. The SFX acts as a Low-hitting trap that cannot be 'blocked' standing, and only one may be active at a time.
If the opponent comes in contact with it, they'll be blown upward into the air and land in a soft knockdown (Comboable). If Koichi himself steps on it, he will be sprung high into the air akin to a Super Jump ability, allowing him to evade many of the opponent's attacks or set up his own attacks from the air.

Special Moves (Stand On)

Hit them, ACT3!

+ // ON GROUND

ACT3 flies forward a moderate distance while rapidly punching, pushing the opponent away. (Flash Cancel comboable)

S-H-I-T

+ // ON GROUND WHEN DOWNED

ACT3 rises upward and comes down punching with the power of 3 Freeze active, knocking the opponent down. This skill is a Middle attack that cannot be blocked crouching, functions as an anti-air, can strike a downed opponent, and inflicts the 3 Freeze effect for a short duration. A Stand Rush skill that Koichi can disconnect from to freely act while it is executing.
Of note is that this skill will not lose its Middle-hitting property when Stand-Rushed, allowing Koichi himself to assail a defending opponent with crouching normals while ACT3 simultaneously attacks from above, resulting a high-low offense that is difficult to defend against. (Flash Cancel comboable)

This air pressure?!

+ /// ON GROUND

ACT3 swiftly moves in front of Koichi and unleashes a potent burst of air that will knock both him and the opponent (if they're in range) back a long distance. This skill is a combo-breaking ability capable of interrupting an opponent attacking Koichi, and unlike other skills of its kind, does not cost any Heart Heat to perform. Instead, however, Koichi is self-harmed in the process for a substantial amount of extra damage, half of which is silver damage. Koichi may recover the silver health over time, but only if he does not receive any more damage again during the process.

Throw

Whooooosh!

2 ATK buttons at close range or ON GROUND

Koichi shoves the opponent off-balance while ACT2 whips them with a "Whooosh!" SFX from its tail, sending them flying.

Heart Heat Attack / Great Heat Attack

Echoes ACT3: THREE FREEZE!!

+ 2 ATK Buttons ON GROUND

Koichi sends ACT3 flying forward a considerable distance, rapidly punching with the power of 3 Freeze active for an extended period of time. The opponent is pushed away, and the final hit will knock them down. Successfully landing the attack inflicts the 3 Freeze effect for a medium-length period of time.
This HHA does not require an initial hit to connect in order to work, and will not stop until it finishes or Koichi is interrupted.

I'm really getting stronger?!

+ 3 ATK Buttons, or ON GROUND

Koichi first summons Echoes ACT1 to throw a "BAM!" SFX projectile forward. If it connects, the opponent is assaulted by booming SFX loudly repeating itself, forcing them to cover their ears. ACT2 opportunistically flies in and slaps a "KaBOOM!" SFX on the floor under them, blasting them skyward. Finally, ACT3 suddenly appears above the airborne opponent and charges up 3 Freeze, then assaults them with an intense barrage of punches. The final strike causes ACT3 to pass through the opponent, before they fall with increased gravity and smash harshly into the ground.
This GHA inflicts the 3 Freeze effect for a long period of time.

Gameplay Overview

Koichi is an unorthodox fighter who can wield Echoes' unusual array of powers for a variety of scenarios. Due to his notably small stature (bested only by Iggy as the smallest character), he can play highly evasively and avoid his opponent's attacks with ease. Juxtaposing this is his long-reaching normal attacks and skills that can extend far away from him, allowing Koichi to apply offensive pressure at mid-range. His skills when utilizing ACT1 and ACT2 focus on crude utility, offering more diverse specials to play defensively or in skirmishes. Meanwhile, ACT3's abilities are more simplistic and emphasize a close-ranged offensive playstyle, with the threat of 3 Freeze being a valuable tool as well as an readily available, if not punishing combo breaker.

Koichi's weaknesses come in his small size and the fluidity of his arsenal. His size makes him easier to juggle and thus combo, coupled with lower-than-average health can render him vulnerable to heavy damage. A rare negative quality of his is that his set of skills, while fine individually, lack cohesion. Koichi's moves seldom flow well into each other on offense, possessing poor 'hitstun' or launching effects unsuited for use in combos. This results in him being a rather awkward character who is more limited in combo potential and damage output than most.

In all, Koichi aims to play around his opponent's attacks, using his small size yet large attacks to outmaneuver and punish mistakes accordingly. While in effective range to use ACT3's strength, he can apply 3 Freeze to force the opponent on the defensive, opening up opportunities to freely assault them with little chance of them retaliating.

Miscellaneous

Aside from being a playable character, Koichi also appears on the stage "Kira Estate" as a background character, if he himself is not one of the two fighters, along with Okuyasu. Koichi also appears as the auto-save icon, with his face under the effects of Heaven's Door as the pages flip.

Koichi uses unique dialogue before a fight with Jotaro or Giorno, telling the latter that he wants his suitcase luggage back, recreating their antagonistic dynamic during early Part 5 before they leave on good terms.

Koichi also won the first place in his League Group in the All-Star Battle League, beating fan favorites such as Giorno, Jolyne, and Gyro. He even managed to reach to the semi-finals matches, but ultimately lost to Jotaro.

[edit]

Eyes of Heaven (PS3/PS4)

Koichi was confirmed for the game alongside Yukako.

Once again Koichi is voiced by Romi Park and his main color scheme is the same from the previous game.

Since most of the game's animation, effects, and attacks were reused from All-Star Battle, Koichi's style of play remains mostly the same; focusing on using a variety of abilities across Echoes' different ACTs.

As a Stand User, Koichi is one of many characters with wildly varied abilities that grant him uniqueness in battle.

• Style Action - ACT1/ACT2/ACT3: Koichi cycles Echoes through its different ACTs, completely changing the skills and attacks available to him. Each ACT specializes in a certain area: ACT1 grants useful buffs and debuffs despite its low attack and skill count; ACT2 focuses on ranged attacks and traps, being able to throw its tail as a projectile in exchange for melee; ACT3 grants access to normal melee combos and conventional moves involving its punches and 3 Freeze.

While ACT1 is active:

• Trust me!: ACT1 throws an SFX with some homing capabilities at his partner, and if it connects, they are granted a boost in stamina and the Dual Heat Gauge is filled by a small amount. This skill is unavailable if Koichi's partner is out of range. If partnered with Yukako, the skill's effectiveness is increased.

• I hate you!: ACT1 throws an unblockable SFX with some homing capabilities at an opponent, and if it connects, the target's defense and stamina gauge is lowered, and the enemy team loses an amount of their own Dual Heat Gauge. If fighting against Yukako, she is immune to this effect while her "I can't hear you!" passive skill is active.

While ACT2 is active:

• Boing!/Whooooosh!: The attack unleashed is dependent on whether or not the movement stick is tilted in a direction while the skill is inputted. If inputted from neutral, ACT2 slaps an SFX on the ground in front of Koichi. If an opponent comes in contact with it, they'll be blown upward into the air taking no damage. If Koichi himself touches it, he will leap high into the air, allowing him to evade many of the opponent's attacks or set up his own attacks from the air. If inputted while moving, ACT2 instead swings its tail horizontally, placing a different SFX on a wall (of note is that the in-game description erroneously claims the surface to be the ground) if available or dealing small damage to an opponent in-range otherwise. If an opponent comes in contact with the SFX, they'll be blown backward a great distance, still taking no damage.

• Sizzle!: ACT2 utilizes an offensive SFX from its tail to catch opponents on fire and cause them to gradually lose health. The execution of the skill is dependent on whether or not the movement stick is tilted in a direction when it is inputted. If inputted from neutral, ACT2 throws the SFX in a straight line with an indefinite range as a projectile. If inputted while moving, ACT2 slaps the SFX on the ground where it becomes a trap. If the skill is executed in the air, the projectile version is performed by default.

• Bahyoo!: ACT2 whips its tail outward with it semi-transformed into an SFX. If it connects with an opponent, they take moderate damage and are sent flying a large distance away.

• EX - Sizzle!: The SFX gains a damage boost, and the projectile version of the skill flies faster.

While ACT3 is active:

• 5-METER RANGE ACHIEVED. S-H-I-T!: ACT3 generates a short gravity field around itself, dealing a small amount of damage to opponents and immediately downing them. This inflicts 3 Freeze's effect, dubbed Heavy. Once in effect, targets will be unable to jump, and their movement speed is much slower for a period of time. Similar to All-Star Battle, if Heavy is inflicted on Kira's Sheer Heart Attack, it will be immobilized for a period of time.

• Echoes 3 Freeze!: ACT3 flies forward, unleashing a barrage of 8 punches and pushing opponents away while inflicting Heavy.

• Wh-What is this wind?!: ACT3 swiftly moves in front of Koichi and unleashes an intense burst of air capable of knocking both him and the opponent back. This skill is unblockable and creates a large amount of distance if successful. However, Koichi is knocked down and takes a small amount of damage in the process.

• EX - 5-METER RANGE ACHIEVED. S-H-I-T!: The duration of the Heavy effect inflicted is increased.

JoJolities

• Trust me!: Koichi must connect "Trust me!" twice. (200 Points)

• You're no match for Echoes ACT2!: Koichi must connect "Sizzle!" twice.(200 Points)

• My ACT3 is awesome!: Koichi must inflict Heavy 3 times. (300 Points)

• ACT3 Freeze!: Koichi must perform a Dual Combo Finish. (500 Points)

• I have protected you as ordered.: Koichi must Retire an opponent with a Dual Heat Attack. (800 Points)

Dual Heat Attacks

• Solo - I'm really getting stronger?!: Identical to its performance in All-Star Battle, though executes faster for the sake of brevity. It also still inflicts Heavy afterward.

• With Josuke - Dorara Rush ×2: Koichi has Echoes ACT2 place SFX of Crazy Diamond's Stand Cry ("DORARARA!!") directly under the opponent's feet. He then prompts Josuke to attack, watching as he jumps high into the air until he is directly above the opponent. The SFX then activates, creating artificially-made fists to attack from below as Crazy Diamond punches the opponent from above, hitting them from both sides. This is the only DHA available to Koichi that does not involve 3 Freeze and therefore does not inflict Heavy.

• With Yukako - Invincible Heroine: Koichi uses 3 Freeze to make the opponent heavier, then Yukako wraps them in her hair before attempting to fling them around. Despite struggling with the increased weight of the opponent, she successfully slams them into the ground four times before raising them extremely high up into the air and launching them into the ground one more time hard enough to generate a shockwave.

• With Rohan - We're best friends!: Koichi uses 3 Freeze to make the opponent heavier, before Rohan uses Heaven's Door to write in the opponent "My weight will increase 10-fold.", combining the effects and multiplying their weight to such a degree that it causes them to slam face-first and sink into the ground with enough force to generate a crater.

In the new timeline in the story mode's post-credits scene, Koichi bumps into Jotaro. He claims to experience deja vu, feeling that he met Jotaro somewhere before.

Tournament

He is paired with Will A. Zeppeli in the Eyes of Heaven Tournament but was eliminated in the preliminaries by Jonathan Joestar and DIO.
