Fan Made Heroic Spirits Reboot

Yuno Gasai - Berserker - Future Diary

Class: Berserker 

True Name: Yuno Gasai 

Alignment: Chaotic Mad 

Original Series: The Future Diary (Mirai Nikki)

Lore: Yuno Gasai is a figure defined by obsession, tragedy, and madness, her life a twisted narrative of love turned into compulsion. In her original timeline, Yuno was an ordinary girl pushed to the brink by abusive parents, ultimately becoming a participant in a deadly survival game orchestrated by the God of Time and Space. Her defining trait is her overwhelming, unyielding obsession with Yukiteru Amano, the boy she loves. This obsession drives her to commit unspeakable acts, eliminating anyone who stands between her and her desire for eternal happiness with him. She is cunning, resourceful, and unpredictable, acting with an almost superhuman intensity fueled by her singular purpose. As a Berserker-Class Servant, Yuno's madness remains intact, enhancing her already extreme behavior and clouding her judgment further. Her actions blur the line between love and insanity, as her loyalty to her Master mimics the dangerous fixation she held for Yukiteru, making her both a powerful ally and a volatile danger. Her summoning draws on the twisted threads of fate that intertwine life, love, and destruction, casting her into battle with the same desperation she exhibited in her deadly game. 

Summoning Relic: A shattered pink cell phone, representing Yuno's Future Diary, which once predicted Yukiteru's every action and allowed her to safeguard his life.

Class Skills:
-Mad Enhancement (EX): Yuno's already unstable mental state is heightened to a terrifying degree as a Berserker, granting her immense physical strength, heightened speed, and unmatched endurance. Her love-fueled madness drives her to ignore injuries that would cripple other Servants, making her relentless in combat. At this rank, her reasoning deteriorates almost entirely, replaced by an instinctive need to protect what she deems precious—whether her Master or an imagined version of Yukiteru. The intensity of her obsession manifests in unpredictable behavior, shifting her combat style between ruthless efficiency and erratic violence without warning. Mad Enhancement's drawback lies in her erratic nature; moments of lucidity might flicker through the haze, but they only serve to fuel deeper despair and more reckless aggression. Even powerful Command Seals struggle to control her once she is fully lost in her rage, making her a double-edged sword on the battlefield. The line between love and bloodlust blurs completely under Mad Enhancement, reducing the battlefield to a twisted stage for her obsessive desires. 

Personal Skills:
-Love Obsession (A+): Yuno's existence is defined by her overwhelming obsession with the object of her affection. In life, this fixation was directed at Yukiteru, but in her summoned state, it transfers entirely to her Master, making her disturbingly loyal to them. This obsession grants her a powerful focus, allowing her to perform feats of strength and agility beyond what her parameters suggest, as long as her actions align with her protective instincts. However, this devotion is a double-edged sword—any perceived betrayal or neglect from her Master triggers violent emotional outbursts, turning her from a guardian into a berserk force of destruction. Her obsession clouds her judgment, making it difficult for her to discern friend from foe, and her world narrows to the point where her Master becomes the sole reason for her existence. This unwavering loyalty is a boon in battle but a curse outside of it, as her fixation can become a liability in situations that require diplomacy or subtlety. 

-Future Sight (B): A remnant of her Future Diary ability, Yuno retains a limited form of precognition that allows her to foresee events a few seconds ahead. This skill grants her a decisive edge in combat, enabling her to anticipate enemy actions with uncanny precision and react accordingly. However, the foresight is imperfect, clouded by her madness and emotional instability. Visions of possible futures bleed into each other, and her obsession causes her to misinterpret certain events, leading to rash decisions. In combat, however, this brief foresight makes her almost impossible to surprise, allowing her to evade fatal blows and exploit openings in her enemies' defenses. The skill also amplifies her paranoia, making her suspect betrayal at every turn, which only fuels her erratic behavior. 

-Yandere Instinct (C): Yuno's inherent ability to detect and eliminate threats to her obsession manifests as a near-supernatural awareness of danger. She instinctively senses when someone harbors ill intentions toward her Master or interferes with her goals, allowing her to act preemptively. This instinct sharpens her reflexes, making her deadly in close combat as she strikes with ruthless precision against perceived threats. However, the same instinct causes her to misinterpret harmless actions as hostile, leading to unnecessary violence. This skill renders her incredibly protective but also dangerously unstable, as even innocent bystanders may become targets if she believes they pose a threat to her desired outcome. Her combat prowess is heightened by this instinct, but her unpredictability makes it difficult for allies to rely on her without fear of unintended consequences. 

Noble Phantasm(s): 
-Name: Bloody Vow – Till Death Do Us Part
-Rank: B 
-Type: Anti-Unit 
-Ability: This Noble Phantasm symbolizes Yuno's promise to love and protect at any cost, even if it means bringing destruction. Upon activation, Yuno binds herself to a single target, typically her Master, forming an unbreakable connection fueled by her obsession. As long as the bond is active, Yuno's physical capabilities receive a significant boost, and she gains an unrelenting drive to protect her chosen person. However, if the target of her affection is harmed or expresses doubt in her abilities, the bond triggers a violent backlash. Yuno enters a state of uncontrollable rage, unleashing devastating attacks against anyone within her vicinity, including allies. In this berserk state, her strength increases further, but her mind becomes completely lost to the madness. The only way to break the Noble Phantasm is through Yuno's death or the death of the bonded target. This ability reflects the dual nature of her love—a powerful force that grants life and strength but also carries the potential for catastrophic destruction.
