Chapter 216 of Sakamoto Days, titled “Tunnel,” picks up amidst ongoing events and reveals how Shin Asakura, the deuteragonist, survived despite Kei Azuki channeling Takamura’s persona and slitting his throat with a sword. The explanation comes from Atari, the enigmatic character with the ability to manipulate luck. She claims Shin survived due to the “Tunnel Effect,” a quantum physics phenomenon where a particle can pass through a barrier it seemingly doesn’t have the energy to overcome. In layman’s terms, she explains that Kei’s sword never actually made contact with Shin’s throat and went through it. Thanks to her luck-based powers, she amplified the chances of this near-impossible event becoming reality. Naturally, this twist has sparked widespread reaction, with fans now humorously applying the tunnel effect to rewrite pivotal death scenes across other Shonen Jump series.
