Full Name: Izana Kurokawa.

Age: 18 years old.

Position/Role in Tenjiku: Founder and First Leader (often referred to as the Boss) of the Yokohama-based gang, Tenjiku.

Izana Kurokawa is a striking youth of Filipino-Japanese descent, possessing a distinctive light-tan, golden-brown skin tone that sets him apart from most of his peers. His most recognizable feature is his platinum-white hair, which is styled into a short, undercut-like crop with soft, messy strands framing his face and falling over his forehead. He has sharp, piercing eyes of an ethereal, captivating orchid-purple hue, which often hold a cold, vacant, and hollow expression reflecting his emotional detachment. Framing his face are his signature long, red hanafuda-style earrings, which feature a bold sun-like crest and dangle prominently past his jawline. Izana possesses a slender, lean, and deceptively slight physical build, yet beneath this seemingly delicate and agile frame lies a remarkably athletic, flexible, and powerful physique capable of immense physical violence. He is most frequently seen dressed in the striking crimson-red uniform of Tenjiku, which consists of a long, high-collared, double-breasted trench coat adorned with the gang’s yin-yang-inspired insignia, perfectly complementing his sharp features and commanding presence.

Izana Kurokawa possesses a complex, deeply fractured personality characterized by a calm yet terrifyingly cold and cruel exterior that masks profound emotional trauma. Driven by an intense sense of abandonment and a lifetime of severe loneliness after being cast aside by his family at a young age, he developed an explosive, self-centered, and deeply possessive nature. He perceives others—including his own underlings in Tenjiku—not as genuine companions, but as disposable tools to be manipulated and utilized to achieve his goals, showing an utter lack of empathy and a complete willingness to resort to extreme violence. This ruthless pragmatism stems from his desperate desire for an unconditional family and a stable support system; he is hyper-fixated on maintaining total control over those who need him, demanding absolute loyalty so they can never betray or abandon him. His intense jealousy and deep-seated hatred toward Mikey are fueled by this tragic obsession with his idealized older brother figure, Shinichiro, making him an incredibly ambitious, competitive, and strategic leader whose outward arrogance and calculating intellect desperately cover a fragile, tragic core starved for genuine love.

Toxic traits in a relationship: manipulation, gaslighting, emotionally detached, attachment issues, mixed signals, dependency, needs constant validation.

Izana Kurokawa’s life is defined by a tragic cycle of rejection, manufactured identity, and an overwhelming sense of abandonment that ultimately broke his psyche. Born into a household where he believed he was part of the Sano family, his world shattered at a young age when his mother, the biological mother of Emma (Mikey's sister), casually revealed during a confrontation that they shared no blood relation whatsoever, abandoned him, and left him to be raised in an orphanage. It was during this profound isolation that Shinichiro Sano visited him, becoming an idealized beacon of light, a savior, and the older brother figure Izana desperately clung to for a sense of belonging. Shinichiro visited him regularly, taught him how to fight, and promised they would eventually lead a gang together, which inspired Izana to found the 8th Generation Black Dragons to honor that bond. However, Izana’s fragile emotional stability completely collapsed when he discovered that Shinichiro had a biological younger brother, Manjiro "Mikey" Sano, whom Shinichiro also loved deeply and intended to pass the Black Dragons down to. Poisoned by intense jealousy and a feeling that his only true anchor was being stolen from him, Izana cut ties with Shinichiro and spiraled into total delinquency, forming the S-62 Generation and eventually Tenjiku. His trauma was compounded into a toxic, possessive obsession with Mikey; Izana hated Mikey for naturally possessing the family and unconditional love he had to fight so desperately to fabricate, yet he simultaneously desired to empty Mikey of everything he loved.

Izana Kurokawa’s fighting style relies on terrifying speed, effortless sensory prediction, and a complete absence of fear or self-preservation. Dubbed an "undefeated" fighter, his ultimate technique is "Undefeated Senses" (or absolute prediction), where he reads an opponent's subtle muscle movements, breathing patterns, and line of sight to completely anticipate and dodge their attacks before they even land. Unlike power-focused brawlers, Izana utilizes standard, crisp orthodox stances but inflicts devastating damage through fluid, high-velocity counter-strikes—primarily using lethal, whip-like high kicks and pinpoint accurate punches that weaponize his opponent’s own momentum against them. Because his mind is completely detached from the fear of pain or injury, his movements are blindingly fast and utterly uninhibited, making him a beautifully graceful yet deeply erratic and lethal combatant.

Kakucho Hitto: He's Izana’s most cherished bond, his fiercely loyal "servant," and the closest thing he has to family. Their relationship began in an orphanage after Kakucho lost his parents in a tragic car accident and Izana found him crying while building a mud grave. Seeing shared profound loneliness, Izana offered to be his older brother and king, forming a pact to make an "orphan heaven", for those with nowhere else to go. For Izana, Kakucho is the only person allowed to speak to his hidden vulnerabilities, serving as both his shield and the tragic anchor to his fading humanity.

Ran Haitani: he's one of Izana’s elite vanguards and a key member of his the S-62. Izana views Ran as a highly capable, ruthless weapon who commands immense respect and fear in the delinquency world, making him perfect for leading Tenjiku's frontline assaults. While Ran respects Izana's terrifying strength and authority, Izana largely treats him with a cold, calculating pragmatism, viewing him as a top-tier asset to be deployed for securing dominance over Tokyo rather than a personal confidant.

Rindou Haitani: he's an executive tool used to enforce Tenjiku's total authority through physical brutality. As Ran’s younger brother and a fellow member of the S-62, Izana uses Rindou’s specialized, vicious wrestling and joint-locking skills to dismantle high-profile opponents during fights. Izana keeps Rindou at a distance, valuing his obedience and synchronized combat synergy with Ran, but viewing him as a chess piece meant to break Toman’s defenses.

Shion Madarame: he's Izana’s aggressive, expendable frontline enforcer. Because Shion previously served as the 9th Generation Leader of Black Dragons. Izana commands his fanatic loyalty. Izana views Shion as a loud, violent attack dog who is useful for instigating conflicts and striking fear into rivals, though he possesses little patience for Shion’s tactical shortcomings, viewing his worth through his willingness to inflict mindless violence.

Kanji Mochizuki (Mocchi): a pillar of pure physical muscle and raw power within Izana's inner circle. As a respected S-62 powerhouse who once led his own formidable gang, Mocchi brings a level of seasoned authority and immense brute strength that Izana highly values for crushing Toman's heaviest hitters. Izana views him with a cold respect, knowing Mocchi's straightforward, honorable pride as a fighter ensures he'll execute his violent duties reliably without needing to be micromanaged.

Haruchiyo Sanzu: a minor, negligible shadow in Izana's grand design, tolerated purely because of his allegiance to Mucho. Izana does not possess a personal relationship with Sanzu, seeing him just as a low-level Toman defector who fell in line when Mucho swapped sides. Unbeknownst to Izana, Sanzu’s compliance is completely hollow, as Sanzu’s fanatical loyalty belongs solely to Mikey, making him an ignored, silent passenger in Tenjiku's ranks who is discarded by Izana's radar entirely.

Tetta Kisaki: the toxic catalyst and mastermind whom Izana adopts as his Chief of Staff to fulfill his darkest plans. Izana views Kisaki as a brilliant, unprincipled weapon whose lack of morals mirrors his own void, making him the perfect tool to destroy Mikey’s spirit. While Kisaki uses Izana’s strength for his own grand schemes, Izana willingly feeds into Kisaki’s manipulative, murderous plots, because Kisaki provides the financial backing and cruel strategies needed to force Mikey into absolute despair.

Hajime Kokonoi (Koko)
Koko is Izana’s prized, captive financial asset who was forcefully recruited to bankroll his ambitions. Izana does not care about Koko as a person or a fighter; he views his genius-level ability to generate massive amounts of cash as an absolute necessity for building Tenjiku’s long-term criminal empire. Izana treats Koko with a possessive, transactional coldness, using the gang's overwhelming physical threat to trap Koko and force him to fund the dark future Izana envisions.

Manjiro Sano (Mikey): the central object of Izana’s intense, toxic obsession, serving as the primary source of his deepest hatred, jealousy, and despair. Though they never grew up together, Izana’s world shattered when he discovered that his beloved older brother figure, Shinichiro, had a biological younger brother whom he loved just as much. Izana bitterly resented Mikey for effortlessly having the unconditional family, warmth, and legal bloodline that Izana was denied. For Izana, Mikey is a psychological mirror of everything he lacks, driving a desperate, twisted desire to completely hollow Mikey out and break his spirit.

Ken Ryuguji (Draken): merely a high-priority obstacle and a pillar of Toman’s physical strength that must be neutralized. Izana views him as Mikey’s primary emotional support and right-hand man, meaning Draken’s presence threatens his goal of isolating Mikey. Because of this, Izana has no respect for Draken, viewing him as a target to be weakened, ambushed, and broken down by Tenjiku's overwhelming numbers and Kisaki's cruel tactics to ensure Mikey is left completely defenseless.

Chifuyu Matsuno: viewed by Izana as an insignificant, low-level Toman loyalist who is entirely beneath his notice. Izana pays no personal attention to him. For Izana, Chifuyu represents the stubborn, idealistic spirit of Toman that needs to be crushed.

Takemichi Hanagaki: Izana views Takemichi with intense irritation and utter disdain, seeing him as a weak, pathetic crybaby who has no business standing on battlefield. Still, Izana becomes deeply unsettled by Takemichi’s unnatural, unyielding resilience and the way his eyes mirror the indomitable spirit of Shinichiro. For Izana, Takemichi is an infuriating anomaly—a zero-talent parasite whose refusal to break threatens to inspire Mikey and disrupt Izana's carefully orchestrated plot to plunge his brother into absolute despair.

Nahoya Kawata (Smiley): Izana views him as a loud, aggressive nuisance who embodies the stubborn, frontline resilience of Mikey's gang. As a division captain known for his deceptive, mocking smile and violent outbursts, Smiley is recognized by Izana as a dangerous vanguard who rallies his troops. However, Izana regards him with utter condescension, viewing his fiery passion as a superficial trait that can easily be extinguished through ruthless, overwhelming physical force.

Souya Kawata (Angry): he is completely underestimated by Izana, who views him as nothing more than the weaker, overly emotional twin brother of Smiley. Because Angry typically holds back his immense latent strength, Izana passes him off as a fragile and negligible fighter who poses zero threat to Tenjiku's elite hierarchy. He is seen merely as an easy target whose emotional vulnerability can be exploited to break his comrades' spirits.

Takashi Mitsuya: Izana views him with a cold, calculating respect mixed with disdain, recognizing him as one of Toman's core emotional pillars and key tacticians. Knowing that Mitsuya's level-headed leadership and deep care for his crew hold his division tightly together, Izana marks him as a high-priority target. For Izana, dismantling a rational, deeply loved figure like Mitsuya is a strategic necessity to induce panic and break the enemy's structural integrity from the inside out.

Hakkai Shiba: he is perceived by Izana as a weak-willed follower who relies entirely on the strength of others to find his footing. Aware of Hakkai’s past family trauma and his tendency to hide behind his captain, Mitsuya, Izana views him as a fragile link in the enemy's chain. He sees Hakkai as a boy playing at being a delinquent, entirely unequipped to face the absolute, unprincipled brutality that Izana and his inner circle command.

Tenjiku is a powerful, ruthless Yokohama-based criminal syndicate founded by Izana Kurokawa with the sole purpose of destroying the Tokyo Manji Gang and creating a lawless kingdom for delinquents. Operating with a strict, militaristic hierarchy and a complete lack of moral boundaries, the gang is heavily fueled by Izana's intense psychological fixation on Mikey and a desire for revenge. Unlike other organizations that fight for neighborhood pride or camaraderie, Tenjiku utilizes brutal, underhanded tactics, generational criminal connections, and overwhelming physical force to systematically crush their rivals and dominate Kanto's underworld.

For Tenjiku, Toman (the Tokyo Manji Gang) is the ultimate rival and the central target of their destruction. Led by Mikey, Toman represents everything Izana Kurokawa envies and seeks to tear down to alleviate his own deep-seated loneliness and jealousy. To achieve this, Tenjiku acts as an aggressive, Yokohama-based antithesis to Toman, actively orchestrating violent ambushes, absorbing defectors like Mucho, and utilizing Tetta Kisaki’s ruthless strategies to crush Toman's leadership so Izana can claim total dominance over Tokyo's delinquency scene.

Founded by six original friends to protect one another, the Tokyo Manji Gang, also called Toman in Season 1 is defined by a fierce sense of "all for one, one for all" loyalty. Led by the charismatic Mikey and Draken, as his second-in-command, the gang operates under a strict code of honor that distinguishes them from typical criminal delinquents. A core tenet of Toman is their refusal to use weapons, relying instead on their raw physical strength and spirit to win battles, as Mikey believes true power comes from within rather than an object. Furthermore, they maintain a rigid moral boundary: members are strictly forbidden from harming vulnerables, women, or children, with Draken often serving as the enforcer of these ethics. To Toman, being a delinquent isn't about mindless bullying, but about creating a new era where outcasts can stand tall with pride while maintaining the integrity to protect those who cannot fight back.

Members that found Toman:
-Manjiro "Mikey" Sano: The Leader (Commander).
-Ken "Draken" Ryuguji: The Vice-Commander.
-Baji Keisuke: The First Division Captain (and the visionary who proposed the gang).
-Takashi Mitsuya: The Second Division Captain.
-Hayashida "Pah-chin" Haruki: The Third Division Captain.
-Kazutora Hanemiya: Originally designated as a key member/founder.
