It's
New Year's Eve! As usual, it's time to get your kimonos out, eat festive hot meals, visit the temple for the bell ringing, to meet others, to get mochi from the Hares of Inaba pounding it and try to avoid the flying bits of mistletoe going around and making people kiss.
And if you meet Lucifer, he's decided to distribute otoshidama envelopes this year. As you're all children in his eyes, don't be surprised to get money from the King of Hell, even as he looks like an old man in a wheelchair.
