I guess it's a niche one,
Hint: A rerun of the show was pulled from television because what happened in the anime happend irl at the time so it was a sensitive topic
If I am guessing correctly it should be Tokyo Magnitude 8.0? Subway Surfers might be referring to Tokyo's almost endless subway network and Kaiju might be referring to the size of the earthquake? and the anime was also re-run after the 2011 earthquake in Japan.
