Isobe Isobee Monogatari: Ukiyo wa Tsurai yo

Isobe Isobee is a samurai who spends much of his time lounging at home, avoiding responsibilities, and secretly reading Edo-era adult material when his mother isn't looking. Despite his lazy habits and frequent naps, he dreams of one day becoming a respected warrior. His mother remains supportive and holds a high opinion of him, unaware of his idle lifestyle.
