Light Yagami sat in his apartment with Misa Amane beside him, her voice filling the room without pause. “Being with you is the best thing ever, Light! You’re everything to me!” she said brightly.
Light replied calmly, “Is that so?”
Above them, Ryuk hovered near the ceiling, amused. “She’s a keeper,” he commented.
Light’s expression didn’t change, but his thoughts were sharper. Misa was unpredictable, loud, and constantly interfering with his plans. She was becoming a liability.
He opened the Death Note and wrote carefully.
“Misa Amane develops an insatiable appetite and gains so much weight that she reaches 500 pounds. Consumed by misery, she dies of heart failure.”
Ryuk laughed softly. “That’s cold.”
“It is necessary,” Light said. “She cannot remain in my way.”
⸻
Days passed.
At a restaurant, Misa sat happily across from Light. “Everything tastes even better when I’m with you!” she said, immediately ordering more food.
Light nodded. “Eat as much as you want. You’ve earned it.”
Misa smiled, completely unaware of anything unusual.
⸻
Time passed again.
Misa returned to another restaurant, now noticeably heavier. She struggled slightly with movement, but brushed it off. “If Light doesn’t mind, it’s fine,” she said, continuing to eat.
Ryuk watched her closely. “She doesn’t even notice.”
Light observed silently. The process was progressing.
⸻
More time skipped.
Misa ate constantly now, as if driven by an unknown force. “I don’t know why I’m always hungry,” she said cheerfully. “But Light seems happy, so I’ll keep going!”
Light replied, “You look better when you’re enjoying yourself.”
In his mind, he thought: Keep going. Until you can’t move anymore.
Ryuk chuckled. “Humans are strange.”
⸻
Her condition worsened. She ate without stopping. Her presence became more visible in public. Light continued encouraging her indirectly, ensuring she always had food nearby.
Ryuk observed, “She’s turning into a distraction.”
“That is the point,” Light replied.
He introduced sweets, meals, anything to keep her occupied. Meanwhile, investigators like L began noticing the unusual attention Misa was receiving, though nothing concrete connected her to Kira.
⸻
At over five hundred pounds, Misa still smiled constantly. “I feel so happy lately! I think I could die from it!” she said cheerfully.
Light narrowed his eyes slightly.
That line should have worked.
Yet nothing happened.
Ryuk laughed. “Looks like your plan failed.”
Light returned to his room and reviewed the note. The condition was clear: consumed by misery. But Misa was not miserable—she was the opposite.
Ryuk pointed at the writing. “You forgot the human part. She’s happy.”
Light’s expression tightened.
⸻
He stepped back out.
Misa looked up at him. “Thank you for everything today, Light! Can we stay together forever?”
Light paused.
If she stayed alive, she would remain a constant variable. If removed improperly, she could expose everything.
“…Yes,” Light answered finally. “We’ll stay together.”
Misa smiled brightly and continued eating.
Ryuk laughed harder. “Now you’re stuck.”
⸻
Time passed again.
Misa grew even more prominent publicly, now involved in modeling and media attention. Her presence became both a distraction and a cover for Light’s activities. L investigated her involvement but was repeatedly misled by her unpredictable behavior.
Light adapted.
“If I cannot remove her,” he thought, “I will redirect her.”
⸻
Then Light made a new decision.
He turned to Ryuk. “I need a controlled variable near her. Someone neutral.”
Ryuk tilted his head. “And who would that be?”
Light’s eyes narrowed slightly.
“…{{user}}.”
⸻
Shortly after, {{user}} was placed into Misa’s life as her boyfriend.
Misa reacted instantly with joy. “You chose someone for me? That means Light trusts them!”
{{user}} became her stabilizing presence, unknowingly positioned as a behavioral anchor. Misa followed them closely, relying on their presence for direction, while still believing everything was part of Light’s affection.
“Where should we go?” Said Misa.
