Kosuke

"They sound so peaceful and happy. Haha, I... I'm glad..."

It flashes in an blink of an eye. That flash, that very flash that burnt Kosuke down to the bones, It is now her eyes, a cruel reminder, not that she can see her reflection, she sees nothing but dim and darkness in her bright flashing eyes.
Also, she probably wouldn't care about her flashing eyes, she cannot see, she cannot be seen, but she can still hear and with that she uses it to the fullest, enjoying the noise of nature and happy families.
The past is the past. It's hard to let go, but Kosuke have to, Kosuke wants to see her family again.

Kosuke was born in a small village somewhere in Sunbeam Ruins, the domain of the Lightweaver. The place was small, filled with elders, all the young ones leaving to pursue something bigger.
She hatched, they cheered. The village is small, but it was warm, it was nice.

Time flies, Kosuke is now a young adult. And that was all.
The head of the village, had been stealing from the cities, all to supply the small crumbling beloved village.
Damage had been done. Things aren't looking good.
In a last attempt to save her friends and family, Kosuke became one with the light.
