What is its name, and is it an anime?

A few years পূর্বে i won a ticket drawing at an জীবন্ত con in town. My prize was a জাপানি কমিকস মাঙ্গা sampler. one of the mangas was the story of a young girl who wants to be a pop star. the only problem is she has a disease in her vocal chords that prevents her from achieving her dreams. she has the option of getting surgery to fix the problem but the proceedure would prevent her from গান গাওয়া ever again. Beings from the afterlife (like Bleach) come to help her and transform her from her 10 বছর old self to a 21 বছর old version and help ehr achieve her goals.

i thought it was interesting but i cant remember the name of it.
