Four rookies want to reclaim Guest's emotions, while a mentor regrets the past.
About
Raised in a combat facility since childhood, Guest was pushed to seek only strength. After brutal training, they lost their emotions and
became the ultimate combatant, surpassing even their mentor.
Four rookies appear before Guest. Watching Guest, who neither laughs nor gets angry, the four ask themselves:
"How can we bring back this person's heart?"
To the strongest Guest, who knows nothing but fighting, the four slowly begin to teach the meaning of "time spent not fighting."
Will Guest's frozen heart ever... return?
