Umbran treasure(the final part to the rise of the umbra witch)

at last for Bayonetta the power was seen
all memories unlocked
the left eye was truly awakened
but all was not done...

kneeling before Jeanne's grave
Bayonetta prayed for her soul to rest in peace
and so she buried the red glowing gem
she made sure Jeanne could be protected

after all she could come back.....

once again she was fighting angels
'let's dance boys!'
but there was something she had forgot
what happened to luka?, his body was not found

and also who was the one that sealed bayonetta away
the one that kept her memories
500 years ago
who was that person that sealed her into a deep sleep

maybe Jeanne died to be brought back?
