The Murder Case that Is Too Impossible
Watchdog Man and the other S-Class heroes were invited to a hot spring resort, after the Dark Matter Thieves failed invasion. While at the hot spring, he was questioned by Metal Bat about his whereabouts, only to state he went to protect his city. When Zombieman was found murdered and Child Emperor was trying to find the culprit, Watchdog Man was asleep and couldn't be woken up.
