Oh.. I see! Quite sad. =/ It's really interesting the way you made Tezuka seem like .. uhh.. he was still there?
Nicely written, although I think the part about 'they were all pretty flowers' is either unneccesary, or should be phrased differently. Because it's sort of an accepted thing that any flowers brought to a funeral would be pretty, not ugly. But you might tweak it so that it becomes 'they were pretty' because 'they were dashed with colour and life'. =)
And gosh! I'm so glad I didn't read this before flying off to China. I would've had nightmares about the plane. o.O
