Summary
Highlights
The video introduces the two Kiras, Light Yagami and Yoshikage Kira, highlighting the vastly different scales of their crimes. Light operated globally as a self-proclaimed god, while Yoshikage committed a series of unsolved murders in a small town. The central question is which case would be truly harder to solve, particularly for a regular police force.
This section analyzes how easily a murder would be detected, considering cause of death, traceability, crime scene clues, and body discovery rate. Yoshikage Kira's crimes were almost undetectable; for 15 years, women vanished without a trace due to Killer Queen erasing all evidence. Light's killings, however, involved clear and consistent causes of death (heart attacks, broadcast publicly), making them highly identifiable but untraceable to a physical killer. Yoshikage Kira's case wins in this category due to its inherent undetectability.
This part examines how well each killer concealed their identity through personality and daily habits. Light Yagami used his reputation as a top student and son of a police officer as camouflage, remaining composed even under surveillance. However, his ego often led to impulsive actions. Yoshikage Kira avoided attention, lived a routine life, and was socially distant, making him blend into the background almost perfectly, despite a few risky moments like carrying a severed hand in a bakery. Yoshikage Kira's stillness and routine make him harder to read and thus win this category.
This category focuses on how actively each killer manipulates and outsmarts the investigation. Yoshikage Kira primarily used defensive tactics, narrowly escaping by changing faces or using Bites the Dust to loop time. Light Yagami, conversely, actively planned multiple steps ahead, using his father's police access, staging events like the busjacking, and orchestrating complex schemes like the memory loss plan and the fake 13-day rule. Light Yagami clearly wins this category due to his proactive and manipulative tactics.
This section assesses external factors that shaped the difficulty of each case. Light's case operated on a massive global scale with hundreds of deaths, ensuring public and international attention. The supernatural nature of the Death Note made it untraceable, but its patterns allowed for logical deduction. Yoshikage Kira's crimes took place in a small town with no investigative resources and no visible trail. His case relied heavily on chance encounters, supernatural intervention (ghosts), and uncontrollable coincidences for its resolution. Yoshikage Kira's case is deemed more difficult circumstantially because it existed in an evidence vacuum, requiring immense luck and supernatural intervention to be solved.
Ultimately, the video concludes that Yoshikage Kira's case would be harder to solve. Light Yagami's downfall came from deduction, while Yoshikage Kira's relied on fate and impossible coincidences. In a realistic scenario, Yoshikage Kira's crimes would likely never have been solved at all, requiring significant luck and supernatural elements for resolution. Therefore, the Yoshikage Kira case takes the title of the harder case to solve.
