(from ebookjapan):

Hajime Saito is a young man with nothing to show for his wealth. He has been evicted from his apartment for nonpayment of rent, and wanders around town with nothing to show for it.

Saito, who has nowhere to turn, is drawn to trivial insects such as mayflies and minnows, which attract no one's attention. Insects and people, both of whom have only a fleeting and short life, are no different in the sorrow of living...

Leiji Matsumoto depicts the cruelty and toughness of life in this sad one-shot collection.
