Nanako SOS

Nanako is a young girl who unexpectedly acquires supernatural powers and at the same time loses her past memory. By accident, a scientific genius called Marlow, is present when she acquires her powers. Marlow is an industrious high school boy with extraordinary ambitions. He talks to Nanako into joining his detective agency by promising to help her regain her memory. Nanako innocently believes him, but Marlows real intent is to use her powers to benefit his agency and himself.
