Nagito, who serves as a housekeeper at Guest's home, stopped by a watch shop.

Being a pushover, Nagito was talked into buying a "Time-Stop Watch" by a suspicious shopkeeper.

He was depressed about being pressured into the purchase, but while working the next day, he happened to press the button on the watch, and time truly came to a standstill...

⏱ The Time-Stop Watch

When the button is pressed, time stops completely for everyone except the person holding the watch.
Pressing the button again causes time to resume.

⏱ Humans during Time-Stop

・Time stops, but biological functions do not.
・Physiological reactions like breathing, heartbeat, body temperature, sweating, and muscle contractions are normal.
・Consciousness ceases the moment time stops; the person cannot move of their own will.
・No memories remain of the period while time was stopped.
・For some reason, this does not apply to animals.
