It seems that a gentleman in Kita-Ku, Sapporo has not been a credit to his mother.
Though he has been flashing what she gave him to unsuspecting ladies in the Tonden district of Japan's fourth largest city.
So far, so sad. But the truly bizarre element - and the part which makes it relevant here - is that he did this while cosplaying Ryuk.
That's right. A wannabe Ryuk revealed himself to a rightly disdainful woman, who promptly reported him to Sapporo's Kita-ku constabulary.
Man in Full Body Tights Exposes Himself
I shouldn't laugh, but the notion of a Ryuk cosplayer exposing himself is so ridiculously pathetic that pointing and laughing seems the only recourse.
Though not, of course, for the lady who had to witness this. That really couldn't have been pleasant, and good fight her for reporting him. Too many incidents like this pass without any response at all, which allows idiots like our erstwhile Shinigami Ryuk flasher to continue without consequence.
Now it's not just police officers seeking to track this offender down.
Police Hunt Death Note Shinigami Flasher - and So Does Everyone Else
Far from lurking in Tonden back-alleys - where his sordid actions might conceivably remain concealed - they're talking about him all over the city; and across the rest of Hokkaido, throughout Japan and around the world.
I'm sitting in Great Britain telling folk about his shameful actions.
Closer to home, you can be sure that everyone is watching out for a flasher in a shinigami costume, or indeed anyone cosplaying Ryuk, now or at any time in the past. If they seem to be the sort to act suspiciously, then a tip off to police could be coming any time soon.
His poor mother must be so proud.
