Sugurogi's physical ability is at an Olympic level. He can fight 1 vs 10 opponents.
Sorry, I don't mean to be rude, but it seems like you're completely missing the point of this show, it's not about a realistic depiction of police work, journalism or even restaurant ownership, it's just a Xmas story, so a slightly superheroic vibe is fine, as far as I'm concerned (and it seems that long chain of unrealistic coincidences is ok for you, but not for me).
