Robin couldn't save Sunday.
She was the one who always says the strong must protect the weak. She went and away to every corner of the sky to lend her hand to those in need. She was busy spreading the power of Harmony to disarrayed order and disaster.
She was too busy to realize that the one who need her help the most is right beside her.
"Brother... I couldn't save brother..." she said while hugging herself.
Robin curled her body, making her small compare the rest of the universe. She was shattered. Droplets of tears jumbled with messy sobbing.
There was no place for Robin to lean on anymore.
so, Firefly was there. With her silver armor, she embraced the weak and wounded Robin. The scorching fire of the flame knight became gentle warmth, protecting the songstress from cold-prying eyes of evil and disgrace.
"But now, there's two of us." Firefly whispered.
Robin took a sharp gasp. A wave of hope washed her as the embrace around her tightened.
"Let's go save your brother. This time, we will make it."
This time, Robin will save Sunday.
