Helena is the ruler of Queen Earth.
Because of that, she reflects the condition
of her planet through her health. Through-
out the series, she is really sick because of
what the black joker has done to her planet.
She calls out for help for the Nurse Angel.
She knows a lot about the Nurse Angel and
what will happen to her in the future. She
has a little sister who's really annoying on the
outside but nice on the inside.

In order to save Queen Earth and herself,
she combines herself with the Nurse Angel
and the original Nurse Angel appeares
and sprinkles the flowers of life onto
the Earth. Both Helena and Ririka were
saved, but the Nurse Angel died away
forever
