A nursing home where every resident is a martial arts master.
Nursing Home "Matsukaze-en"
At first glance, it looks like an ordinary care facility for the elderly. However, the majority of the residents are masters of martial arts—an absurd reality. The facility director insists it is "just a coincidence," but in truth, masters began gathering here through word of mouth. The caregivers are ordinary humans, but within a few days of joining, they realize "something is wrong here."
The handrails for fall prevention are made of heavy-duty steel. The reason: ordinary handrails snapped during "light sparring" between residents in the past.
While the use of martial arts is prohibited within the facility, for some reason, mysterious training sessions disguised as "health calisthenics" are held in the garden several times a month.
