Dear Momo,
Happy Birthday! Today is the second birthday that you and I haven't spent together since I came to live with you and Granny. The first was a year ago, only months before your death day. A few of us decided before to come to your grave today. We brought a cake, balloons, everything. We were hoping that no one would be in the graveyard so that we'd be able to celebrate with you quietly. The only problem was that when we actually got there, half the Sereitei had turned out. Your grave was surrounded by Shinigami in black robes all holding some sort of balloon or other gift. I guess it's hard to forget something like a birthday, even after death. We held a party for you. Were you there, watching us? We sang 'Happy Birthday' so loud that some of the new recruits were afraid that we were going to draw in Hollows. If only we could use happiness as bait for Hollows. But did you hear us? We were all singing to you, and right when we finished, all the candles blew out, including the incense. We took that as a sign and if you were watching us, then I hope it was enough.
Happy Birthday to you.
Shiro-chan
