Omnipresent No Kami (KazuScara kinda)

There once was a puppet, scorned since creation.
Left by his mother to wander the lighting nation.

Friends did he make, a swordsmith; his family.
But there was, one day, a great catastrophe.

The swordsmith was fated to die that day,
Cut straight through the heart by a harbinger, they say.

That heart to be given to the puppet as a trick
A betrayal, a lie, his innocence snatched away fairly quick.

But what if fate's wheels were on that day turned
To cause the puppet instead to be cast into the future not yet learned?

In Mondstadt, Liyue, Inazuma, Sumeru, not quite,
No one knows the identity of the boy dressed in white.

However, his double, his future self in this world still exists
Read this here possible redemption arc, I insist.
