Black Calamity Wanders the Universe [Honkai: Star Rail]

I haven't figured out the blurb yet.

The last thing Khaslana remembered was Bai E thrusting a sword through his chest. With rage and hatred toward the Creator, he entered eternal sleep.

That should have been the end, but he opened his eyes again in the universe.

It was the universe as it had been hundreds of years earlier. He searched everywhere, but couldn't find a trace of Amphoreus.

He passed through many planets, including Penacony, which was in the midst of war. He met figures such as Gopher Wood and the Watchmaker, helped them overcome their crisis, and became a sneaky hen. With no clues about his home, he left and headed for the next place.

Next came the Xianzhou. After resolving the Vidyadhara crisis, he became a sneaky hen with Wuyun, too, and asked them to help search for clues about Amphoreus. Unfortunately, they found nothing, so he left and continued his search.

In the end, he found the Astral Express Crew setting out on a new journey. With the power of Trailblaze, he entered Amphoreus and helped Bai E achieve true Re-Creation.

He looked at how much he had changed and saw Bai E sharing an unbreakable bond with his companions. He wondered whether he was just in the way, and left without a word.

But just after he left, the friends he'd met across the universe caught up with him, declaring, "You'll always be our favorite sneaky hen!"

1: This is a story about a black cat-dog wandering through the universe and, before he knows it, finding a crowd of cat-dogs and dragons following him around and snuggling up to him!

2: This Khaslana is basically a copy-paste with an extra data packet, inexplicably appearing in the universe. There's no known reason! I just really wanted to see this trope!

Theme: All your efforts will eventually pay off
