Once again a failure

[AU: Regressor Og!Cale and Siren KRS!Cale]

What if KRS!Cale failed to kill white star and died along with his family? While on the other hand Og!Cale from another parallel earth regressed only without the transmigrating?
They're both now in the same world
One one side KRS!Cale is a Siren the forgotten beautiful monster of the ocean. He is going around and saving his close companions and children while staying low and not letting anyone outside his 'family' circle know about his existence.
While on the other side OG!Cale who regressed with his memories has chosen a different path this time, to save his family and world by cooperating with the heroes of the Roan kingdom and using his memories of the past.

Two Cale's with the mindset to destroy White Star for killing their family what could go wrong?

I wonder what OG!Cale will do when he sees new faces, Faces that were not present in his past world.

And on the other hand what will KRS!Cale do when he sees that OG!Cale and much worse he has regressed is in this world as well....

Evem more worse ...they look exactly the same!! Someone might call them twins if they didn't know them!!
