Description by LuffyNoTomo

Kuuki no Soko is a collection of short stories drawn by the genius mangaka, Tezuka Osamu, between 1968 and 1970, and is known in Japan as a true masterpiece.

Belonging to Tezuka's most mature period, it touches many genres: from pure science fiction to historical fiction to contemporary drama. We find stories of industrial espionage, animal testing, and racial animosity, as well as stories about the more complex dynamics of the human mind.

And the human mind is the leitmotif of the entire volume, namely the duality present in every one of us - mercy, love, and understanding, existing together with cruelty and violence until something upsets the balance and we discover a side hidden even from ourselves... a side we are not always prepared to confront...
