Mio, the Kunoichi (female ninja), is on a secret mission to penetrate
the Tower of Early Summer Rain.
The Tower is on the far end of the Lake.
Mio attempts her intrusion through the Aquaduct,
but no kunoichi has ever made it through alive.
Long watery corridors without even a chance to take a breath of air.
Craftily hidden underwater killer traps.
She has no safeguards,
save her remarkable breathholding ability
and her marvelously trained physique.
...See Mio in her adventure
through this fearsome underwater labyrinth!
