The original story is in french, I just translated it. If you want to see the original it's name is Recueil Pour un Samourai and was written by Elghim.
The birth of Kenshin
A young child named Shinta
Roaming through the japanese regions
But his entire life went to hell
One evening which was announced rather good
His entire family being attacked
By greedy plunderers
His mother laying at his feets her throat cut
His time will come soon
Then a stranger arrived
His hand at his scabbard
And in a magnificent body move
Sent in hell his torturers
This child is the sole survivor
Kenshin was then his new name
Even if this man was intimidating
His invitation he accepted
He then learn to fight
As he was training
His long hair flowing in the wind, scarlets
To defend everything he loved
Since then a great warrior was born
Protecting the widow and the orphan
And of his blade making pay
Those who were going astray of the right path
