The first time I heard of Hanako san was from an anime :3
A short, silly Gmod animation I put together for Halloween, in case I can't finish my main Halloween animation in time. Just a short skit involving a Toiletta from Yo-kai Watch, a.k.a Hanako from the Japanese urban legend.
There's a small reference to the Hanako horror survival game in here. It will likely go over your head if you haven't seen much of the game.
