Today, Mira was unusually in the club room from the start. Sitting by the window, gazing outside.
"Mira, you're early," Yuki called out.
Mira turned and wrote something in her notebook to show them. "Entropy always increases"
"Entropy always increases."
Aoi approached with interest. "Are you talking about the second law of thermodynamics?"
Mira nodded. Unusually, her expression showed a hint of melancholy.
"What's wrong, Mira?" Yuki asked worriedly.
Mira continued writing. "My room. Messy. Cannot decrease entropy."
"Your room is messy, and you can't decrease entropy," Yuki laughed. "Everyone has that problem."
But Mira was serious. She wrote on the next page. "Order → Disorder. Natural law."
"Order to disorder. Natural law."
Aoi said quietly. "Indeed, increasing entropy is inevitable. In a closed system, disorder increases with time."
"But can't you just clean it up?" Yuki suggested.
Mira shook her head and wrote. "Requires energy. System not closed."
"Requires energy. System not closed."
"I see," Aoi understood. "Mira is troubled by the essence of entropy."
Mira nodded and wrote a longer sentence. "Life fights entropy. But ultimately loses. Melancholy."
"Life fights entropy. But ultimately loses. Melancholy."
Yuki thought deeply. "True, everything eventually falls apart."
"But," Aoi said gently, "locally, we can decrease entropy."
Mira looked up.
"Life takes in energy from outside and maintains its own order. Like cleaning a room."
"But for the universe as a whole?"
"The entropy of the entire universe increases. But within it, we can create local order. That's the beauty of life."
Mira smiled faintly.
Aoi continued. "Information entropy is the same. Data degrades over time, and noise increases. But we can counter it with error correction codes."
"We keep fighting," Yuki said.
Mira wrote. "Temporary order. Is it meaningful?"
"Temporary order. Is it meaningful?"
Aoi answered. "Meaning isn't in the length of time. It's in the beauty of the moment."
Mira quietly shed tears. Yuki approached in surprise.
"Mira, what's wrong?"
With trembling hands, Mira wrote. "I am also entropy. Forgetting. Losing information."
"I am also entropy. Forgetting. Losing information."
Aoi gently placed a hand on her shoulder. "But forgetting is also necessary. If we remembered everything, our brains would overflow."
"Selective deletion of information," Yuki supplemented.
Mira looked up. "Then... entropy is not enemy?"
"Then entropy is not the enemy?"
"Not the enemy," Aoi declared. "Entropy enables change. Perfect order means stagnation."
"Because there's disorder, new order is born," Yuki understood.
Mira took a deep breath. Then wrote. "Life = fighting entropy + accepting entropy"
"Life equals fighting entropy plus accepting entropy."
"A beautiful definition," Aoi acknowledged.
"Mira is a philosopher," Yuki smiled.
Mira regained some energy. She wrote on the last page. "Thank you. Reduced my mental entropy."
"Thank you. Reduced my mental entropy."
"That's good," Aoi laughed. "But if it increases again, let us know."
Mira nodded. And for the first time in a while, she smiled slightly.
Outside the window, cherry blossom petals were scattering. Orderly flowers falling in disorder. But that disorder creates the beauty of spring.
"The melancholy of the entropy girl, solved?" Yuki asked.
Mira wrote. "Ongoing. Like life."
"Ongoing. Like life."
The three laughed quietly. Entropy continues to increase. But within it, they can enjoy each moment of order.
